I need a super simple, privacy-focused uptime monitoring service for my personal projects that has a good free tier.

If privacy is the priority, I’d narrow it to these:

1. Uptime Kuma — best for privacy

• Open-source and self-hosted, so your monitoring data stays under your control.
• Free software with no artificial monitor limit.
• Supports HTTP(S), TCP, Ping, DNS, Docker, notifications, status pages, and more.
• Downside: you have to run it yourself (e.g. on a small VPS, home server, or NAS).
• My pick if you’re comfortable with Docker.

2. betterstack.com — best hosted option

• Very simple UI and setup.
• Free personal tier currently includes 10 monitors + 10 heartbeats + 1 status page, with 3-minute checks.
• Much less infrastructure hassle than self-hosting.
• Downside: you're trusting a third party with your monitoring information.

3. uptimerobot.com — best if you want lots of monitors

• Free tier currently offers 50 monitors, 5-minute checks, and a basic status page.
• Its privacy policy says it doesn't sell users' private personal information, although it does use third-party vendors/analytics.
• Downside: less privacy-oriented than self-hosting.

My recommendation

For personal projects where you really mean "privacy-focused", I'd choose Uptime Kuma. It's hard to beat having the monitoring system—and its data—entirely under your control.

If you want zero maintenance, choose Better Stack. Its free tier is particularly nice for just a handful of personal sites.

If you tell me whether you're willing to self-host (Docker/VPS), I can narrow this down to the simplest possible setup.

If you truly care about absolute privacy and want a 100% free setup (with no corporate SaaS tracking your project endpoints or metadata), the ultimate gold standard for personal projects isn't a third-party hosted service—it's self-hosting Uptime Kuma.

However, if you want a hosted SaaS that requires zero infrastructure management while still keeping things straightforward, UptimeRobot or Better Stack are the standard lightweight choices.

Here is how the top options break down depending on your definition of "simple":

1. The Ultimate Privacy Choice: Uptime Kuma (Self-Hosted)

If data privacy is your top concern, running your own instance means zero data leaves your infrastructure. It features a gorgeous, modern UI and takes 5 minutes to spin up via Docker.

• Cost: Free (Open Source)
• Free Tier Limits: Unlimited monitors, unlimited status pages, and check intervals down to 20 seconds if you want.
• Privacy Profile: 100% yours. No third-party company logs when your personal projects go up or down.
• Pros: Insanely feature-rich, supports HTTP(S), TCP, Ping, DNS, and Docker containers, and has 70+ notification types (Discord, Telegram, webhooks, email).
• Cons: Requires a tiny server to run on (like a $3/month VPS, a Raspberry Pi at home, or a free-tier Oracle Cloud instance).

2. The Simplest Hosted SaaS: UptimeRobot

If you don't want to host anything yourself and just need to paste a URL and get an email/Discord ping when it drops, UptimeRobot is the classic zero-hassle choice.

• Cost: Generous Free Tier
• Free Tier Limits: 50 monitors with 5-minute check intervals.
• Privacy Profile: Standard SaaS telemetry. They track your endpoint URLs and response times, governed by their privacy policy.
• Pros: Setup takes literally 30 seconds; extremely reliable baseline alerting.
• Cons: 5-minute check intervals on the free tier; locked out of faster checks or advanced status branding unless you pay.

3. The Modern Developer SaaS: Better Stack (Uptime)

If you want something sleeker than UptimeRobot with better incident management and a nicer free tier feature set.

• Cost: Free Tier available
• Free Tier Limits: 10 uptime monitors + 10 heartbeats with faster checks than UptimeRobot.
• Privacy Profile: Standard SaaS telemetry, but widely trusted by developer communities for transparent practices.
• Pros: Beautiful UI, great alert logs, and solid integrations.
• Cons: Strict limits on the number of monitors compared to Uptime Kuma or UptimeRobot.

Would you prefer a fully hosted SaaS that takes 30 seconds to set up (like UptimeRobot), or do you have a tiny server/VPS where you'd be comfortable running a self-hosted open-source tool like Uptime Kuma for absolute privacy?

For a personal project where you care about privacy + simplicity, I’d narrow it down to these:

1. Uptime Kuma — best privacy choice

Best if you can run a tiny VPS, Raspberry Pi, NAS, or home server.

• ✅ Open source
• ✅ Your data stays under your control
• ✅ Unlimited monitors (your hardware permitting)
• ✅ Very simple UI
• ✅ Supports HTTP(S), TCP, ping, DNS, Docker, keywords, and more
• ✅ Status pages and many notification methods
• ❌ You maintain the server yourself

For a privacy-focused person, this is usually the winner: the monitoring provider never sees your URLs, uptime history, or incidents because you host it.

A simple setup is:

• $5/month VPS
• Docker Compose
• Uptime Kuma container
• Email/Discord/Telegram alerts

2. HetrixTools — best hosted free tier

Best if you don’t want to self-host.

Free tier highlights:

• ✅ 15 uptime monitors
• ✅ 1-minute checks
• ✅ SSL/domain monitoring
• ✅ Status pages
• ✅ Server metrics option
• ❌ Your monitoring data lives with a third party

It is one of the more generous free hosted options.

3. Better Stack — nicest UX

Best if you value polish over maximum privacy.

• ✅ Very clean interface
• ✅ Good incident timelines
• ✅ Good for small teams
• ❌ SaaS provider sees your monitoring data

My recommendation for your use case

I’d choose:

1. Uptime Kuma if you can tolerate 15–30 minutes of setup.
2. HetrixTools if you want “sign up and forget it.”
3. Avoid enterprise-style monitoring tools unless you need team features.

For a handful of personal sites/APIs, Uptime Kuma is probably the closest match to “simple + private + free.”

A nice hybrid setup is also common:

• Uptime Kuma for private/internal services
• A hosted monitor like HetrixTools for an external “is my whole server unreachable?” check

That way, the monitor itself is not running on the same machine it is watching.

If you want super simple, privacy-focused, and free , your best paths split into two distinct directions depending on how you define "service": a managed cloud tool with a generous free tier, or a self-hosted open-source tool that guarantees 100% data privacy because it never leaves your hardware.

1. UptimeRobot (The Easiest Managed Cloud Free Tier)

If you want something that takes 60 seconds to set up without managing a server, UptimeRobot is the classic choice.

• The Free Tier: Gives you up to 50 monitors with a 5-minute check interval and basic email alerts.
• Privacy Perspective: They are a standard hosted SaaS (so they see the URLs you ping), but they don’t require a credit card or intrusive personal info to get started.
• Pros: Extremely simple, reliable, and the free tier limit is generous enough for a handful of side projects.

2. OpenStatus (The Modern, Open-Source Developer Choice)

If you prefer modern developer tooling with open-source transparency, OpenStatus is a sleek alternative.

• The Free Tier: Includes 1 monitor, 1 status page, and checks from up to 6 regions.
• Privacy Perspective: The core code is fully open source (AGPL-3.0), meaning you can inspect how it handles data or self-host the checker component entirely via a tiny Docker image.
• Pros: Gorgeous status pages, supports monitoring-as-code (YAML/CLI/Terraform), and gives you the flexibility to move off their cloud whenever you want.

3. Uptime Kuma (The Ultimate Self-Hosted Option)

If absolute privacy is your primary goal—meaning zero telemetry and zero external servers touching your endpoints—run Uptime Kuma on a cheap $4/month VPS or a spare Raspberry Pi at home.

• The Free/Self-Hosted Tier: 100% free and open-source with unlimited monitors, limited only by your own hardware.
• Privacy Perspective: Hermetically sealed. No third party ever sees your project endpoints, logs, or downtime stats.
• Pros: Ridiculously slick UI, supports every notification channel under the sun (Discord, Telegram, Webhooks, email), and handles ping, HTTP, TCP, and DNS checks effortlessly.

User Experiences

“Uptime Robot is one of the best-known uptime monitoring tools. Many developers start there because it is free, simple, and quick to set up.”

“Uptime Kuma is an open-source uptime monitoring tool you run yourself.”

If you're leaning one way, tell me: Do you want a zero-maintenance cloud dashboard (like UptimeRobot) or do you have a small server/Raspberry Pi where you can host it yourself (like Uptime Kuma)?

If privacy is the priority, I’d narrow it to two:

🥇 Best overall: Uptime Kuma

• Free and open source
• Self-hosted, so your monitoring data stays under your control
• Very simple web UI
• HTTP, TCP, ping, DNS, Docker, cron/heartbeat, etc.
• Checks as frequently as every 20 seconds
• Lots of notification options
• Multiple status pages
• 2FA support

Downside: you have to run it yourself. If you already have a tiny VPS, homelab, or Docker host, this is probably the privacy-friendly choice I'd pick.

🥈 Easiest hosted option: UptimeRobot

If you don't want to maintain anything, UptimeRobot is considerably easier. Its current free tier offers 50 monitors, 5-minute checks, and a free status page, with no credit card required.

The privacy tradeoff is that it's a third-party hosted service. Its privacy policy says it collects basic account information and uses third-party infrastructure/analytics providers.

My recommendation

For personal projects, I'd use Uptime Kuma if you have somewhere to host it; otherwise UptimeRobot is the easiest zero-maintenance choice.

If you tell me whether you already have a VPS/Docker/Raspberry Pi, I can recommend the simplest possible setup.

For a super simple, 100% private and control-oriented solution, the best choice is self-hosting Uptime Kuma , an open-source tool with a polished UI that keeps all data on your own infrastructure. If you prefer a managed, cloud-hosted SaaS option with a strong free tier and no server maintenance required, UptimeRobot offers up to 50 free monitors, while Better Stack provides a reliable alternative with great free alerts.

Top Privacy-Focused & Free Uptime Monitoring Options

• Uptime Kuma : The gold standard for self-hosted monitoring. It is entirely free, open-source, stores zero telemetry on third-party servers, and supports HTTP, TCP, and Docker checks with multi-channel alerts.
• UptimeRobot : Provides the most generous free monitor count in the hosted category with 50 free monitors on a 5-minute check interval, though basic plans are restricted to email notifications.
• Better Stack : A polished cloud-hosted choice offering modern incident response workflows, fast check frequencies, and a solid free tier suitable for smaller portfolios.
• HetrixTools : Offers a robust, technically rich free tier featuring 15 uptime monitors and fast 1-minute check intervals on specific free configurations.

Would you prefer a self-hosted tool like Uptime Kuma (where you control all the data) or a fully managed cloud service like UptimeRobot?

If absolute privacy and simplicity are your top priorities, the best approach is either a completely self-hosted open-source tool (where your data never leaves your infrastructure) or a minimalist managed service with a clean data policy.

Self-Hosted (Ultimate Privacy)

• Uptime Kuma
  • The Scoop: A fancy, super-polished, self-hosted monitoring tool that runs effortlessly in a Docker container.
  • Free Tier: 100% free and open-source. You just need a tiny server or a free-tier cloud instance to host it on.
  • Pros: Unlimited monitors, beautiful UI, built-in status pages, and support for 90+ notification channels (Discord, Telegram, Webhooks, etc.). Your data stays entirely yours.
  • Cons: You have to manage the hosting yourself. (Pro-tip: If your monitoring server goes down, you won't get an alert unless you monitor the monitor!)

Managed & Simple (No Self-Hosting Required)

• • The Scoop: The undisputed king of easy, zero-config setup for side projects.
  • Free Tier: Generous free plan covering up to 50 monitors with 5-minute check intervals.
  • Pros: Extremely simple to get running in under a minute; no credit card required.
  • Cons: Checks are limited to 5-minute intervals on the free tier, and it's a third-party hosted service, meaning they see the URLs you ping.
• Better Stack (Uptime)
  • The Scoop: A modern, incredibly fast incident-and-uptime tracker with a gorgeous interface.
  • Free Tier: Includes 10 monitors with faster 3-minute check intervals and 1 status page.
  • Pros: Much faster notification alerts than traditional free tiers, cleaner UI, and great developer ergonomics.
  • Cons: Tighter limits on the number of free monitors compared to UptimeRobot.

Would you prefer to go the self-hosted route (like Uptime Kuma) for maximum privacy, or do you want a hosted plug-and-play service where you don't have to touch a server?

If privacy is the priority, I’d narrow it to two:

🥇 Best privacy: Uptime Kuma

Uptime Kuma is open-source and self-hosted, so your monitoring data stays on infrastructure you control. It supports lots of monitor types and has no SaaS free-tier limits—you’re limited mainly by your own server.

Best if: you already have a VPS, Raspberry Pi, NAS, or homelab.
Downside: you have to install, update, and keep it running yourself.

🥈 Best dead-simple hosted option: UptimeRobot

UptimeRobot is probably the easiest zero-maintenance choice. Its current free plan offers 50 monitors, 5-minute checks, basic status pages, and no credit card, and it's explicitly suitable for personal projects.

It does collect information as a hosted service, though, so it isn't as privacy-preserving as self-hosting. Its privacy policy also provides for a GDPR DPA for qualifying users.

My pick

For a few personal sites, I'd personally choose UptimeRobot unless you already have somewhere to run Docker. If you do, Uptime Kuma is the more privacy-focused answer by a mile.

If you want absolute privacy and zero corporate tracking for personal projects, the gold standard is self-hosting an open-source tool . If you prefer a hosted SaaS with a generous free tier , there are lightweight options that keep data collection to a bare minimum.

Here are the best choices depending on whether you want to host it yourself or use a free cloud tier:

1. The Ultimate Privacy Pick (Self-Hosted):

If "privacy-focused" means you don't want your URLs, response times, or alert history sitting on a third-party server, Uptime Kuma is unmatched.

• The Free Tier: 100% free and open-source (MIT license). You just need somewhere small to run it.
• Why it fits: It has a gorgeous, dead-simple UI [1.3], supports HTTP(s), TCP, Ping, and DNS checks, and lets you push notifications to Telegram, Discord, Slack, or email.
• The Catch: You have to host it yourself (e.g., on a cheap $4/mo VPS, a Raspberry Pi at home, or a free-tier Oracle Cloud instance).

2. The Simplest Hosted Free Tier:

If you don't want to manage a server just to monitor your servers, UptimeRobot is the classic choice for personal projects.

• The Free Tier: 50 monitors with 5-minute check intervals and basic email alerts.
• Why it fits: Setup takes under 60 seconds, it's completely free without requiring a credit card upfront, and it stays entirely out of your way.
• The Catch: It's a traditional closed-source SaaS tool (not privacy-maximized like self-hosting), and free checks only come from a single region with 5-minute gaps.

3. The Modern Hosted Alternative:

If you want something a bit more polished and developer-friendly than UptimeRobot.

• The Free Tier: 10| monitors and heartbeats with 1 status page included.
• Why it fits: Extremely fast incident response, modern UI, and clean logs.
• The Catch: Lower monitor count on the free plan compared to UptimeRobot, and meant to scale into a bigger observability suite.

Would you prefer to self-host something lightweight like Uptime Kuma (absolute privacy), or do you want a ready-to-go cloud free tier like UptimeRobot?

For your criteria, I’d narrow it to three, with one clear favorite:

🥇 Best privacy choice: Uptime Kuma

Uptime Kuma is open-source and self-hosted, so your monitoring data stays under your control. It has a simple web UI, lots of notification options, and supports HTTP(S), TCP, DNS, Docker, and more.

Catch: you have to run it yourself—typically on a VPS, home server, or existing Docker host. So it's free, but not zero-maintenance.

Best if: privacy is more important than having literally zero setup.

🥈 Best hosted option: HetrixTools

HetrixTools offers 15 monitors, 1-minute checks, and global monitoring for free forever. It also has email/webhook-style alerting and status pages.

The important privacy caveat is that it's a hosted service: your monitored URLs and monitoring data necessarily pass through their infrastructure. Also, the free account needs you to log in at least once every 90 days to remain active.

Best if: you don't want to maintain anything and 15 projects/endpoints is plenty.

🥉 Simplest mainstream option: UptimeRobot

UptimeRobot is extremely easy to set up and has historically been one of the most generous free options. However, its free-plan terms have become less attractive for some use cases, so I'd pick HetrixTools over it for a new personal setup.

My recommendation

If by privacy-focused you mean "I don't want another company seeing what I'm monitoring" → Uptime Kuma.

If you mean "I want a privacy-respectful, dead-simple hosted service and don't care about the monitor URLs being visible to the provider" → HetrixTools.

For a handful of personal projects, I'd personally go Uptime Kuma if you already have somewhere to run Docker; otherwise HetrixTools.
