I need an auth-as-a-service provider that's dev-friendly and has better pricing than Auth0 for a B2C app.

Yes. For a B2C app, I’d look beyond Auth0—especially now that Auth0’s B2C Essentials starts at $35/month for just 500 MAU, while Professional starts at $240/month for 1,000 MAU.

My shortlist

Clerk Supabase Stytch Stytch### 1. WorkOS AuthKit — my first pick

This is the one I'd investigate first if pricing + developer experience are your priorities.

WorkOS currently gives AuthKit the first 1 million active users free, including email/password, social login, magic auth, MFA, and passkeys. After that, the published price is $2,500 per additional 1M MAU.

That's an almost absurd difference from Auth0 at scale.

It's also not just a cheap auth API: WorkOS has SDKs for common stacks, including Next.js, and the product is designed around developer-friendly primitives.

I'd choose it if: you're building a serious product and expect potentially tens/hundreds of thousands of consumers.

2. Clerk — best DX

If your priority is "I want auth working today and don't want to build UI around it", I'd seriously consider Clerk.

Clerk gives you prebuilt, customizable sign-in/sign-up/profile components and a strong SDK experience. Its current Pro plan is $20/month billed annually with 50K MRUs included.

It's particularly nice with React/Next.js.

I'd choose it if: developer velocity matters more than squeezing out the absolute lowest marginal auth cost.

3. Supabase Auth — best if you're already on Supabase

If your backend is already Supabase/Postgres, this becomes an easy choice.

The current Pro plan is $25/month and includes 100K MAU, with $0.00325 per additional MAU. The free tier has also been raised to 50K MAU.

The tradeoff is that you're buying into more of the Supabase ecosystem rather than getting a pure standalone identity service.

I'd choose it if: Supabase is already your database/backend.

4. Stytch — excellent consumer-auth specialist

Stytch is worth a look if your app has more sophisticated consumer-auth requirements—passkeys, passwordless, SMS/email, fraud controls, etc. Its B2C product is explicitly designed around consumer applications.

Its free B2C tier includes 10K MAU, and Stytch has emphasized transparent usage-based pricing rather than Auth0-style plan jumps.

I'd choose it if: authentication itself is an important part of your product and you want a lot of control over the auth experience.

What I'd pick

For a typical new B2C startup:

WorkOS AuthKit > Clerk > Stytch > Supabase Auth

But there's an important distinction:

• Cheapest at scale: WorkOS
• Best frontend/dev UX: Clerk
• Best auth-specific platform: Stytch
• Best if you're already on Supabase: Supabase Auth
• Best replacement for Auth0's enterprise-ish breadth: WorkOS

If you tell me roughly MAU (e.g. 5K / 50K / 500K), stack (Next.js, React Native, etc.), and which login methods you need (Google/Apple/email/password/passkeys/SMS), I can do a real cost comparison against Auth0 at your expected scale and recommend one.

This is the one I'd investigate first if pricing + developer experience are your priorities.

WorkOS currently gives AuthKit the first 1 million active users free, including email/password, social login, magic auth, MFA, and passkeys. After that, the published price is $2,500 per additional 1M MAU.

That's an almost absurd difference from Auth0 at scale.

It's also not just a cheap auth API: WorkOS has SDKs for common stacks, including Next.js, and the product is designed around developer-friendly primitives.

I'd choose it if: you're building a serious product and expect potentially tens/hundreds of thousands of consumers.

It's particularly nice with React/Next.js.

I'd choose it if: developer velocity matters more than squeezing out the absolute lowest marginal auth cost.

3. Supabase Auth — best if you're already on Supabase

If your backend is already Supabase/Postgres, this becomes an easy choice.

The current Pro plan is $25/month and includes 100K MAU, with $0.00325 per additional MAU. The free tier has also been raised to 50K MAU.

The tradeoff is that you're buying into more of the Supabase ecosystem rather than getting a pure standalone identity service.

I'd choose it if: Supabase is already your database/backend.

4. Stytch — excellent consumer-auth specialist

Stytch is worth a look if your app has more sophisticated consumer-auth requirements—passkeys, passwordless, SMS/email, fraud controls, etc. Its B2C product is explicitly designed around consumer applications.

Its free B2C tier includes 10K MAU, and Stytch has emphasized transparent usage-based pricing rather than Auth0-style plan jumps.

I'd choose it if: authentication itself is an important part of your product and you want a lot of control over the auth experience.

What I'd pick

For a typical new B2C startup:

WorkOS AuthKit > Clerk > Stytch > Supabase Auth

But there's an important distinction:

If you are building a B2C application, you need an auth provider with a generous free tier, predictable scaling, and an incredible developer experience (DX) that doesn't punish you with Auth0's steep enterprise-tier jumps.

Three standout, dev-friendly alternatives to Auth0 fit this exact profile for B2C apps:

- **The Vibe:** Highly developer-friendly, open-source core (MPL-2.0), and built to handle both simple B2C flows and future B2B needs.
- **The Pricing:** Their Logto Free Plan gives you an astonishing **50,000 MAU** for $0/month. Their Pro plan starts at $24/month and introduces a unique token-based/usage model rather than aggressive flat-rate MAU scaling, which is great if your B2C users log in infrequently.
- **Why it’s great for B2C:** Offers out-of-the-box social logins, passkeys (WebAuthn), customization options to hide branding, and a smooth UI. Check out the Logto Pricing page for details.[](https://logto.io/compare/stytch) [[1]](https://logto.io/compare/stytch)[[2]](https://logto.io/pricing)[[3]](https://docs.logto.io/logto-cloud/billing-and-pricing)

- **The Vibe:** The gold standard for drop-in UI components and deep framework-native integration (especially Next.js, React, and mobile/Expo).
- **The Pricing:** Generous free tier for early-stage development, scaling into predictable per-MAU pricing tiers. While it gets pricier at massive scale, its time-to-market and saved engineering hours make up for it early on.
- **Why it’s great for B2C:** Gorgeous pre-built user profiles, session management, multi-factor auth, and social connections that take literally 10 minutes to wire up. Explore their documentation and features on Clerk.[](https://prelude.so/blog/auth0-alternatives) [[1]](https://prelude.so/blog/auth0-alternatives)[[2]](https://www.propelauth.com/post/6-best-auth-platforms-b2b-saas)

- **The Vibe:** Open-source, modular architecture. You can self-host it completely for free with zero user limits, or let them manage the core.
- **The Pricing:** Their managed service includes 5,000 MAU free, then charges roughly $0.02 per MAU thereafter (with a $100/month minimum on paid cloud tiers). Specific B2C add-ons like account linking or MFA are priced modularly per MAU.
- **Why it’s great for B2C:** You avoid vendor lock-in completely because you own or can self-host the core authentication layer if your budget dictates it. Review their setup options on SuperTokens.[](https://supertokens.com/pricing) [[1]](https://supertokens.com/pricing)[[2]](https://supertokens.com/blog/clerk-alternatives)[[3]](https://www.g2.com/products/supertokens/pricing)

To help narrow down the best fit, tell me:

• What front-end/back-end stack is your B2C app using (e.g., Next.js, Node, React Native, iOS)?
• Roughly how many MAU are you expecting in your first 6 months?

Yes. For a B2C app, I’d look at Clerk, Supabase Auth, and Better Auth before Auth0. The best choice depends mostly on whether you value polished DX or absolute cost.

1. clerk.com — my default recommendation

For a modern B2C application, Clerk is probably the closest "better Auth0" answer.

It gives you excellent React/Next.js SDKs, prebuilt sign-in/sign-up UI, social login, passkeys, MFA, sessions, user management, and good frontend primitives. Current pricing is particularly attractive: Clerk's free tier covers 50,000 monthly retained users, while Pro is $25/month monthly ($20 when billed annually) and includes 50K MRUs.

The important distinction is MRU vs MAU. Clerk doesn't charge simply because somebody created an account; it measures monthly retained users. That can be very favorable for consumer apps with lots of one-time or infrequent users.

I'd pick Clerk if: you're using React/Next.js and want to spend essentially zero engineering time building auth UX.

2. supabase.com — best economics

If you're already considering Supabase for your database/backend, this is a no-brainer candidate.

Supabase Auth integrates directly with Postgres and Row Level Security, and the paid Supabase tier includes 100K MAU before auth overages. It's much more cost-efficient than Auth0 for a large consumer audience.

The tradeoff is that Clerk generally has the nicer "auth product" experience—particularly if you want polished, customizable hosted/prebuilt UI and frontend primitives.

I'd pick Supabase if: your architecture is already Supabase/Postgres-centric or you're expecting a lot of users and want auth to be extremely inexpensive.

3. better-auth.com — best if you're comfortable owning more

Better Auth is open source, so there's no per-user authentication SaaS fee. You can run it yourself, or use their managed infrastructure, which currently starts at $20/month.

This is appealing if your team is strong technically and you don't want to get locked into an Auth0/Clerk-style pricing model.

The downside is exactly what you'd expect: you own more of the system. Clerk is selling you convenience; Better Auth gives you more control.

I'd pick Better Auth if: auth is something your engineering team is comfortable operating and minimizing vendor spend is important.

What I would choose

For a new B2C product, my ranking would be:

1. Clerk — best combination of DX, features, and reasonable pricing.
2. Supabase Auth — best if price and/or Supabase integration dominates.
3. Better Auth — best if you want maximum control and minimal SaaS dependency.
4. Auth0 — only if you have a specific Auth0 capability that the others don't provide.

One particularly important point: don't compare Auth0 and Clerk just by headline MAU price. Auth0's current pricing has discrete tiers and paid B2C tiers can jump substantially; Clerk's current pricing and MRU model can be considerably friendlier for consumer apps.

If you give me your expected MAU (e.g. 10K / 100K / 1M), stack (Next.js, React Native, Flutter, etc.), and auth requirements (Google/Apple, passwordless, MFA, passkeys), I can do a much more concrete Auth0 vs Clerk vs Supabase vs Better Auth cost + feature comparison for your app.

The important distinction is MRU vs MAU. Clerk doesn't charge simply because somebody created an account; it measures monthly retained users. That can be very favorable for consumer apps with lots of one-time or infrequent users.

I'd pick Clerk if: you're using React/Next.js and want to spend essentially zero engineering time building auth UX.

2. supabase.com — best economics

If you're already considering Supabase for your database/backend, this is a no-brainer candidate.

Supabase Auth integrates directly with Postgres and Row Level Security, and the paid Supabase tier includes 100K MAU before auth overages. It's much more cost-efficient than Auth0 for a large consumer audience.

The tradeoff is that Clerk generally has the nicer "auth product" experience—particularly if you want polished, customizable hosted/prebuilt UI and frontend primitives.

I'd pick Supabase if: your architecture is already Supabase/Postgres-centric or you're expecting a lot of users and want auth to be extremely inexpensive.

3. better-auth.com — best if you're comfortable owning more

Better Auth is open source, so there's no per-user authentication SaaS fee. You can run it yourself, or use their managed infrastructure, which currently starts at $20/month.

This is appealing if your team is strong technically and you don't want to get locked into an Auth0/Clerk-style pricing model.

The downside is exactly what you'd expect: you own more of the system. Clerk is selling you convenience; Better Auth gives you more control.

I'd pick Better Auth if: auth is something your engineering team is comfortable operating and minimizing vendor spend is important.

What I would choose

If you are building a B2C application, you need an auth provider with drop-in UI components, smooth social logins (Google, Apple, etc.), and a pricing model that doesn't punish you as your user base grows.

Top dev-friendly, B2C-ready alternatives to Auth0 that offer significantly better pricing or more generous free/starter tiers include:

• Clerk
  • Best For: Unmatched developer experience (DX) and gorgeous, pre-built UI components.
  • The Vibe: Framework-native SDKs (especially for Next.js, React, and mobile/Expo) that let you set up complete user management in minutes.
  • Pricing vs. Auth0: Clerk offers a massive free tier (up to 50,000 Monthly Retained Users), and scales at around $0.02 per user beyond that. It is vastly cheaper and more straightforward for early-to-mid-stage B2C scaling than Auth0's enterprise-focused pricing tiers.
• Kinde
  • Best For: All-in-one product tooling (auth + feature flags + basic billing/subscriptions).
  • The Vibe: Extremely modern, highly generous free tier, and built from the ground up for modern software builders.
  • Pricing vs. Auth0: Kinde’s free tier includes up to 10,500 MAUs with social/email logins, MFA, and custom domains all included. Their paid plans start around $25/month, making it way friendlier on the wallet for bootstrapped B2C projects than Auth0.
• Supabase Auth
  • Best For: Maximum value if you are using (or open to using) PostgreSQL.
  • The Vibe: Open-source, deeply tied to Postgres Row Level Security (RLS), and highly customizable.
  • Pricing vs. Auth0: If you use Supabase as your backend/database, auth is essentially free (generous free tiers up to 50,000 MAUs) and scales into very affordable hosted tiers. Even used standalone, it's a fraction of Auth0's cost.
• Logto
  • Best For: Open-source flexibility with a seamless cloud option.
  • The Vibe: Highly standards-compliant (OIDC/OAuth 2.0), great developer documentation, and rapidly growing mindshare for consumer apps.
  • Pricing vs. Auth0: Offers a very generous cloud tier and the ultimate escape hatch of being able to self-host if you ever want zero per-user cloud fees.

If you want to narrow this down, tell me:

• What tech stack/framework is your B2C app built on (Next.js, React Native, iOS, Python, etc.)?
• Roughly how many users do you expect to have in the next 6–12 months?

I can help you pick the absolute best fit and estimate your exact monthly cost.

Yes. For a B2C app, I’d look at Clerk, Supabase Auth, Stytch, and Kinde before Auth0. The best choice depends heavily on your stack and expected MAU.

1. Clerk — my first choice

clerk.com is probably the closest developer-friendly Auth0 replacement.

It has excellent React/Next.js integration, prebuilt sign-in/sign-up UI, social login, passkeys, MFA, organizations, and a good dashboard. Recent pricing information shows a generous free tier and a $25/month Pro tier, with pricing based on retained monthly users rather than Auth0's more complicated tier structure.

I'd pick Clerk if: you're building a modern web/mobile B2C product and want authentication to basically disappear into your development workflow.

2. Supabase Auth — cheapest if you're already on Supabase

supabase.com is particularly compelling if you're using Supabase Postgres.

Auth is integrated with the database and Row Level Security, so you get a very nice model of:

user → auth identity → Postgres user/profile → RLS

Published 2026 comparisons put the free allowance around 50K MAU, with the paid Supabase plan starting at $25/month.

I'd pick Supabase if: your backend is already Supabase or you want your auth data tightly coupled to Postgres.

3. Stytch — excellent if auth UX is important

stytch.com is worth serious consideration for B2C, particularly if you want passwordless, magic links, OTPs, passkeys, or highly customized authentication flows.

It's more API/component-oriented than Auth0 and is generally pleasant for developers. The catch is that its pricing can become less attractive at higher MAU than Supabase/Clerk, depending on exactly which features you use.

4. Kinde — interesting middle ground

kinde.com has a relatively simple pricing model and modern developer experience. It's especially attractive if you want hosted auth without the complexity of Auth0.

---

What I'd choose

For a typical B2C startup, I'd rank them:

Clerk > Supabase Auth > Stytch > Kinde > Auth0

But there's an important caveat:

• Next.js/React + want the fastest implementation: Clerk
• Already using Supabase: Supabase Auth, by a mile
• Passkeys/passwordless are central to the product: Stytch
• Want very simple hosted auth: Kinde
• Lots of unusual identity requirements / enterprise federation: Auth0

One interesting wrinkle is Better Auth: if you're comfortable owning infrastructure, it's open source and avoids per-MAU SaaS pricing entirely, but you take on more security/maintenance responsibility.

If you give me your stack (e.g. Next.js + Node, React Native, Flutter, Rails, etc.) and expected MAU (10k / 100k / 1M+), I can narrow this down to the 2 cheapest options and estimate the monthly bill at your scale.

I'd pick Clerk if: you're building a modern web/mobile B2C product and want authentication to basically disappear into your development workflow.

2. Supabase Auth — cheapest if you're already on Supabase

supabase.com is particularly compelling if you're using Supabase Postgres.

Auth is integrated with the database and Row Level Security, so you get a very nice model of:

user → auth identity → Postgres user/profile → RLS

Published 2026 comparisons put the free allowance around 50K MAU, with the paid Supabase plan starting at $25/month.

I'd pick Supabase if: your backend is already Supabase or you want your auth data tightly coupled to Postgres.

3. Stytch — excellent if auth UX is important

stytch.com is worth serious consideration for B2C, particularly if you want passwordless, magic links, OTPs, passkeys, or highly customized authentication flows.

It's more API/component-oriented than Auth0 and is generally pleasant for developers. The catch is that its pricing can become less attractive at higher MAU than Supabase/Clerk, depending on exactly which features you use.

4. Kinde — interesting middle ground

If you want a developer-friendly experience that beats Auth0's notoriously aggressive scaling costs for a B2C application, your best options depend on whether you want a drop-in hosted service or a TypeScript-native library.

Here are the top alternatives to consider for a B2C app:

• Clerk : Best overall developer experience (DX) for modern web/mobile stacks . It features gorgeous pre-built UI components (<SignIn />, <UserProfile /> ), incredible React/Next.js and mobile SDKs, and a generous tier system . It tracks Monthly Recurring Users (MRUs) rather than just raw sign-ins , and pricing starts free, scaling down to a predictable $25/mo Pro tier before overages kick in.
• Supabase Auth : Best budget-friendly and database-native option . If you are pairing your app with a Postgres database, Supabase Auth offers an enormous free tier (up to 50,000 MAUs) and bundles auth directly into their flat Pro database plan ($25/mo) with virtually no punishing per-user pricing spikes . It's open-source and fully self-hostable if you want zero vendor lock-in.
• Logto : Best open-source, developer-first CIAM (Customer Identity and Access Management). It is an open-source alternative to Auth0 with a modern management console, great UI defaults, and multi-tenant capabilities . You can self-host it to control 100% of your infrastructure costs or use their managed cloud.
• Better Auth : Best for TypeScript-first teams who want total ownership . It is a rapidly growing open-source framework-agnostic TypeScript auth library rather than a hosted black-box service . You run it directly inside your server/database, meaning $0 per-MAU fees —you only pay for your underlying hosting.

To help narrow this down:

• What is your frontend and backend tech stack (e.g., Next.js, React Native, Node/Go)?
• Are you expecting to scale past 10,000 to 50,000 active users quickly?

Yes. For a B2C app, I’d look beyond Auth0—especially if your priorities are developer experience + predictable/low cost.

My shortlist

🥇 I'd pick Clerk for most B2C startups

Clerk is probably the closest thing to "Auth0, but pleasant to use."

You get polished prebuilt auth UI, excellent React/Next.js integration, organizations, social login, MFA/passkeys, sessions, webhooks, etc. Current pricing is particularly attractive at startup scale: Clerk's published pricing gives you up to 50K retained users on the free Hobby tier, while Pro starts at $25/month.

The important caveat: Clerk's billing metric is monthly retained users (MRU) rather than Auth0's MAU, so don't compare the headline numbers blindly.

I'd choose Clerk if: you're building a modern web/mobile B2C product and want your engineers spending as little time on auth plumbing as possible.

---

🥈 Supabase Auth if price is the priority

Supabase Auth is extremely compelling if you're already using—or are willing to use—Supabase/Postgres.

The current Pro plan is $25/month and includes 100K MAU, with $0.00325 per additional MAU. The free tier includes 50K MAU.

That makes it dramatically cheaper than traditional Auth0 pricing at larger B2C volumes. You also get a very nice architecture if your application data lives in Postgres, because auth and authorization can integrate directly with Postgres/RLS.

I'd choose Supabase if: your stack is already Postgres-centric and you care more about economics/control than having the fanciest auth UX.

---

🥉 Stytch if authentication itself is a product differentiator

Stytch is worth serious consideration if you're doing passkeys, passwordless login, OTP, or sophisticated consumer authentication.

Their current pricing starts with 10K MAU free, and they advertise the full authentication feature set without traditional feature gating.

I'd put Stytch ahead of Clerk if your product has unusually sophisticated authentication requirements; otherwise Clerk's overall DX is hard to beat.

---

Firebase is the boring-but-cheap option

Firebase Authentication gives you 50K MAU at no cost on the Identity Platform pricing model, with additional MAUs charged based on usage.

It's particularly attractive for mobile apps or if you're already deep in Firebase/Google Cloud.

The downside is that I generally prefer Clerk/Supabase's developer ergonomics for a modern web startup.

---

What I'd do

If you gave me no other information:

1. Clerk — best balance of DX, features, and price
2. Supabase Auth — best economics, especially with Postgres
3. Stytch — best if passkeys/passwordless are central
4. Firebase Auth — best if you're already in Google/Firebase
5. WorkOS — interesting wildcard, particularly if B2B could become important

One particularly interesting point: WorkOS AuthKit currently makes user management free up to 1M MAU, although its economics change substantially once you add enterprise SSO connections.

One thing I'd want to know before choosing

Tell me roughly your expected MAU at launch / 1 year / 3 years (e.g. 5K → 50K → 500K) and whether you're Next.js/web, React Native, iOS/Android, or mixed.

I can then calculate the actual monthly cost of Clerk vs Auth0 vs Supabase vs Stytch vs WorkOS at each stage and tell you which one I'd use.

If you are building a B2C application, Auth0 (now under Okta CIC) quickly becomes painful and expensive once you cross low user thresholds. Fortunately, there are several developer-friendly, modern auth-as-a-service alternatives with far more generous free tiers and transparent scaling costs.

The best options for a B2C app depend slightly on your exact tech stack and how you plan to scale:

• Clerk — Best overall developer experience (DX) & UI polish. Clerk features drop-in, beautifully designed pre-built React/Next.js components, hooks, and clean user-management dashboards. It offers a massive free tier covering up to 50,000 monthly active users (measured as MRUs—users who actively return), with Pro plans starting at $25/month plus moderate overages. It's the gold standard if you want to ship a polished consumer auth experience in an afternoon.
• Kinde — Best transparent B2C/pro-consumer pricing. Kinde provides an exceptional developer-first experience with robust support for social logins, passwordless flows, and passkeys. Their free tier includes over 10,000 MAUs, and their scaled pricing structure is notoriously straightforward and cheaper than Auth0 as user counts grow.
• Supabase Auth — Best if you want bundled infrastructure. If your B2C app relies on a Postgres database, Supabase Auth gives you an incredible free tier (up to 50,000 MAUs on the free plan) and integrates natively with Row-Level Security (RLS). Their Pro plan ($25/month) includes 100,000 MAUs before charging fractions of a cent per additional user, making it vastly cheaper at scale than dedicated auth-only SaaS vendors.
• Stytch — Best for passwordless-first B2C flows. If your consumer app leans heavily into passkeys, magic links, or biometric/device fingerprinting rather than traditional passwords, Stytch offers granular API control, clean native UI flexibility, and a more linear pricing curve that avoids Auth0’s brutal enterprise tier jumps.

If you tell me what frontend/backend framework you are using (e.g., Next.js, React Native, Python/FastAPI) and your expected user growth (MAU) over the next year, I can help you calculate the exact cost projection between these options.

For a B2C app, I’d usually avoid Auth0 unless you specifically need its enterprise identity features. The better choice depends on whether you optimize for developer experience, lowest cost, or maximum control.

My shortlist:

My recommendation by scenario

1. You want to ship fastest → Clerk

It gives you the closest "drop in auth and move on" experience: prebuilt UI, session handling, account management, social providers, and good framework integrations.

2. You’re building a consumer app with your own backend + Postgres → Supabase Auth

You get auth without adding another identity vendor, and the database/auth relationship is convenient.

3. You expect millions of users and want low infrastructure cost → Firebase Auth or Cognito

They are less pleasant than Clerk/Auth0 but can be very economical at scale.

4. You might become enterprise later → Consider Clerk + WorkOS or stay with Auth0.

Auth0’s advantage is not basic login; it’s enterprise federation, SAML/OIDC complexity, compliance tooling, and deep identity customization.

A practical B2C startup ranking

1. 🥇 Clerk — best developer experience
2. 🥈 Supabase Auth — best value if you like Postgres
3. 🥉 Firebase Auth — best mobile ecosystem
4. Cognito — best cost at AWS scale
5. Auth0 — best enterprise identity platform, but usually overkill for pure B2C

A few questions would change the recommendation:

• Expected MAU in 12–24 months (10k, 100k, 1M+)?
• Web only, mobile only, or both?
• Need social login, passkeys, magic links, MFA?
• Are you already on AWS/Supabase/Firebase?

For a modern B2C app, Auth0 (Okta CIC) often becomes uncomfortably expensive and heavy once you scale past basic tiers.

The top dev-friendly, B2C-focused Auth-as-a-Service alternatives offer significantly better pricing models:

• Clerk
  • Best for: React, Next.js, and modern full-stack web/mobile apps.
  • The DX: Unmatched developer experience with drop-in, beautifully styled UI components (<SignIn />, <UserProfile /> ), powerful hooks, and seamless session management.
  • Pricing: Generous free tier up to 10,000 Monthly Active Users (MAUs), then scales at roughly $0.02 per MAU, which is substantially cheaper than Auth0's scaling rates.
• Supabase Auth
  • Best for: Developers who want a managed backend-as-a-service with built-in database security.
  • The DX: Excellent if you appreciate PostgreSQL Row-Level Security (RLS) and want your auth tightly coupled with your database layer.
  • Pricing: Massive free tier (up to 50,000 MAUs) and incredibly low paid tiers starting around $25/month, making it arguably the most cost-effective hosted option available.
• Kinde
  • Best for: Consumer-facing software and rapid B2C MVPs.
  • The DX: Highly focused on product builders, featuring out-of-the-box social connections, passkeys, passwordless flows, and user management.
  • Pricing: Highly transparent, developer-first packaging designed specifically to avoid surprise bills as consumer bases grow.
• Firebase Auth
  • Best for: Mobile-heavy B2C applications (iOS/Android) or those deep in the Google Cloud ecosystem.
  • The DX: Rock-solid reliability and massive feature coverage, though the web/React developer experience feels a bit more legacy compared to Clerk or Supabase.
  • Pricing: Offers one of the highest free tiers in the industry (50,000 MAUs) before moving to a very low fractional cent-per-user model.

To help narrow down the ideal fit, tell me:

• What is your primary tech stack (e.g., Next.js, React Native, Python/Django backend)?
• What kind of login methods do you need (just social/Google/Apple, or standard email/password and passkeys)?
