I'm looking for a simple screen-sharing tool for walking customers through a solution in real-time.

If your main goal is live, real-time customer walkthroughs, I’d prioritize something that lets the customer join from a link without installing software.

My picks

• demoroom.io — Probably the closest match. It’s built specifically for sales/support/customer-success demos, works in the browser, and supports live screen sharing plus guided remote control.
• crankwheel.com — A good choice if your priority is “send a link and immediately show them my screen.” Recent hands-on comparisons specifically rate it highly for live sales demos.
• meet.google.com — Best if you already use Google Workspace. It gives you conventional video calls plus screen sharing without introducing another specialized tool.
• teamviewer.com — Better when the walkthrough sometimes turns into hands-on customer support. Its browser-based sharing can start without installation, and it supports remote interaction when needed.
• loom.com — Excellent for recorded walkthroughs, but not my first choice for live sessions. Its strength is recording and sending an instant link afterward.

For your exact description, I'd start with DemoRoom or CrankWheel. If you want something familiar and don't mind a conventional meeting interface, Google Meet is the simplest mainstream option.

If you tell me whether you need (1) customer can join with no download, (2) you can take control of their screen, and (3) free/cheap, I can narrow it to one.

When walking customers through a solution in real-time, the golden rule is zero friction —the customer shouldn’t have to install software, create an account, or hunt for a plugin.

Here are the best simple, browser-based screen-sharing tools ranked by how frictionless they are for the end-user:

• Whereby : Incredibly clean and browser-based. You create a permanent or instant personalized room link (e.g., ://whereby.com ), and the customer just clicks the link to jump right into the video and screen share straight from Chrome, Safari, or Firefox. No downloads required.
• Jitbit Screen Sharing : A completely dead-simple, free, browser-to-browser tool. You go to their page, start a session, and send a direct URL to your customer. It uses peer-to-peer WebRTC technology so the stream goes straight between browsers without routing through a heavy corporate app.
• Google Meet : If you already use Google Workspace, this is an easy default. You spin up an instant meeting link, drop it in a chat or email, and the customer joins via the web. It's universally recognized, though it feels a bit more formal/heavyweight than an instant one-click link.
• Dead Simple Screen Sharing : As the name implies, it's a lightweight browser extension/web app designed specifically to let you share your screen via a short URL link without fussing through calendar invites or software installs.

To help narrow down the best fit, tell me:

• Do you need two-way screen control (where you can click on their screen), or just one-way viewing (where you show them yours)?
• Do you prefer a free standalone tool or something that integrates into an existing CRM/helpdesk?

For live, real-time customer walkthroughs, I’d keep it simple and avoid dedicated screen-recording tools.

• whereby.com — easiest overall. Browser-based, so customers can join from a link without installing anything. It’s particularly nice if you do lots of 1:1 customer calls.
• meet.google.com — best if you use Google Workspace. Quick to launch, familiar to customers, and screen sharing is built in.
• zoom.us — best if you need more meeting features. Very familiar to customers and has robust screen-sharing controls, but it's a little heavier than necessary for a simple walkthrough.
• crankwheel.com — best for sales/support demos. It's specifically designed to get someone looking at your screen quickly, which can be useful when the customer isn't already on a scheduled video call.
• demoroom.io — best if customers need to interact. It adds browser-based co-browsing and guided remote control, rather than just showing them your screen.

My pick: Start with Whereby for straightforward “here, let me show you how this works” calls. If these are primarily sales/support sessions where you want the customer to interact with the product, I'd look at DemoRoom instead.

If you tell me whether you need video/audio, customer screen control, recording, or just one-click screen sharing, I can narrow it to one tool.

When walking customers through a solution, the golden rule is zero friction . You don't want your customer stumbling through downloads, creating accounts, or fighting with browser extensions just to see your screen.

Here are the best simple, no-download, browser-based screen-sharing tools suited for real-time customer walkthroughs:

• Whereby — A browser-first video and screen-sharing tool. You get a permanent, personalized room link (e.g., ://whereby.com ). Customers just click the link, and they are straight in through their browser with no downloads or pins required . It’s clean, lightweight, and allows you to share your entire screen or a specific tab. Check it out on Whereby Meetings.
• Screenleap — Built explicitly for instant sharing. It lets you share your screen directly to any device with a browser via a simple link. The customer doesn’t need to install anything; they just open the URL you text or email them and view your screen instantly. It is ultra-minimalist and gets straight to the point. Visit Screenleap to see how it works.
• Jitsi Meet — A completely free, open-source, and fully browser-based video conferencing option. You can spin up a custom room instantly with a randomized URL, send it to the customer, and share your screen right away with no registration or software download needed on either end. Explore the open-source platform on Jitsi Meet.
• Google Meet — If your customer already has a Google account (or if you just need a reliable standard), starting an instant meeting and dropping the link in a chat allows them to join via browser immediately. It handles high-res window or tab sharing smoothly, though it occasionally prompts a Google login on their end if they aren't signed in. Learn more via Google Meet.

To help narrow down the best fit, tell me:

• Do you need the customer to be able to take control of your screen , or just watch?
• Are you sharing mobile or desktop , and do you need video/audio chat alongside the view?

Here are some of the best, simplest screen-sharing tools for walking customers through solutions in real-time, requiring little to no setup on their end:

• Whereby - Browser-based video and screen sharing with zero downloads or installs required for your customers. You just send them a custom room link, and they click to join directly from their web browser.
• Jamm - Lightweight video-conferencing designed for quick, ad-hoc collaboration and screen sharing with instant link generation.
• Google Meet - Highly accessible since most customers already have a Google account or a modern browser, allowing you to share your screen via a quick calendar or chat link.
• Zoom - The industry standard that most users are already familiar with, though it may prompt a quick download if they don't have the app installed.
• Screenleap - Ultra-simple, instant screen sharing that lets customers view your screen directly in their browser via a short URL without any software installation.

If you'd like to narrow this down, tell me:

• Do your customers need to share their screen with you , or do you only need to show your screen to them?
• Do you prefer a tool that runs entirely in the browser without any downloads?

For walking customers through a solution live, I’d keep it simple and use a video-meeting tool with one-click screen sharing rather than a dedicated “screen-sharing” product.

My top picks

1. Zoom — best overall

   • Very familiar to customers.
   • Share your entire screen, a specific app, or part of your screen.
   • Supports annotation, so you can point things out while explaining.
   • Good choice if you expect to do lots of customer walkthroughs.

2. Google Meet — simplest if you use Google

   • Customers can join from a browser.
   • You can share a tab, window, or entire screen.
   • Particularly convenient if your workflow already revolves around Gmail/Google Calendar.

3. Loom — best for demos that don't need to be live

   • Excellent for recording a quick walkthrough and sending it to a customer.
   • Has tools like cursor following, highlighting, and drawing that make product explanations clearer.
   • I'd use this as a complement to live calls rather than a replacement.

If your requirement is specifically “I send the customer a link, we get on together, and I immediately walk them through it,” I'd pick Zoom or Google Meet. If you tell me whether customers need to share their screen back with you, give you control of their computer, or simply watch your screen, I can narrow it down to the best tool.

If the goal is “send a customer a link and start walking them through something live with minimal friction,” I’d shortlist these:

• Whereby — simplest general-purpose choice. Browser-based, no download for customers, and you can keep a permanent room link. Good for 1:1 customer walkthroughs.
• CrankWheel — best for sales/customer demos. Built specifically around quickly getting a prospect onto your screen, including spontaneous calls where you don't want to spend time setting up a meeting.
• Google Meet — best if you already use Google Workspace. Familiar, straightforward, and includes screen sharing without requiring customers to install an app.
• Zoom — best if customers already expect Zoom. More features than you need for simple sharing, but very familiar and reliable for customer calls.
• DemoRoom — interesting purpose-built option. It combines browser screen sharing with guided remote control/co-browsing, which is useful if you sometimes need to let the customer interact with what you're demonstrating.

My pick: Start with Whereby if you want a simple meeting + screen sharing experience. Choose CrankWheel if this is primarily a sales/support workflow where minimizing customer friction is the priority.

If you tell me whether you need just your screen shared, or also the ability to see/control the customer's screen, I can narrow it down to the best 1–2 options.

• Whereby is browser-based, meaning your customers don't need to download or install anything. You just send them a custom link, and they click to join your room. The free tier gives you a personal room with basic screen sharing.
• Jitsi Meet is a completely free, open-source video conferencing and screen-sharing tool. Like Whereby, it requires zero installation for guests—just spin up a room with a custom URL and share the link.
• Droplr or CloudApp (Zight) are fantastic if you want something lighter than a live video call. You can record a quick 5-minute screen share with your webcam and microphone, and it instantly generates a link you can drop in a chat or email.
• Google Meet or Zoom are the heavy hitters. Almost everyone is familiar with them, making adoption frictionless if your customers already use them daily. You can start an instant meeting and text or email the link.
• Loom is the gold standard for asynchronous screen sharing. If the issue doesn't strictly require a live, back-and-forth video call, you can record your screen and voice in one click and send the customer a playback link.

To help narrow this down, let me know:

• Do you need live, real-time interaction , or would recorded video links work better?
• Do your customers have strict IT restrictions that block software downloads?

For walking customers through a solution live, you’ll usually want something with a “click a link → share screen → talk” workflow rather than a recording tool. Good options:

For your use case, I’d pick:

• Simplest customer demo: Zoom or Google Meet
• Customer support where you may need to guide their actions: TeamViewer
• Product walkthroughs you want customers to watch later: Loom

A few features worth prioritizing:

• Browser join (no app download)
• Ability to share only one window (protects your desktop)
• Mouse/annotation tools
• Session recording (with customer permission)
• Ability to hand over control temporarily

If you tell me whether you need only to show your screen or to take control of the customer’s screen, I can narrow it down.

For a friction-free experience where customers do not need to install software or log into an account, browser-based tools that run via a simple generated link are best. Top options include Dead Simple Screen Sharing for instant zero-login peer sharing, Screenleap for viewing directly in any device's browser, or standard web-conferencing standbys like Zoom and RingCentral which allow guests to join instantly via web clients.

Zero-Installation & Browser Tools

• Dead Simple Screen Sharing : A completely free, extension- or sign-up-free utility that lets you start broadcasting your browser or desktop straight from a web link with integrated text chat.
• Screenleap : Enables you to share your screen instantly to any device (including mobile phones and tablets) without requiring the viewer to download an app or software.
• Jitbit Screen Sharing : A lightweight, peer-to-peer, browser-based screen broadcaster that streams directly between peers without routing video heavy data through external servers.

Lightweight Meeting & Video Platforms

• Zoom : The most widely recognized platform; customers can skip downloading the desktop app by simply clicking the browser-join link provided in your meeting invite.
• RingCentral Video : Lets you launch one-click video and screen-sharing sessions directly from a web browser without forcing an upfront software installation on your client.

If you can tell me whether your customers prefer purely view-only presentations or if they need to take control of your screen , I can narrow down the ideal tool for your workflow.
