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

If you mean live, two-way screen sharing while you talk a customer through something, I’d keep it simple:

• Zoom — probably the most straightforward choice. You can share your entire screen, a specific app, or part of your screen, and customers can interact with you in the meeting.
• Google Meet — a good lightweight option if your customers already use Google Workspace; it keeps the experience familiar and browser-based.
• Whereby — useful if you want a very low-friction experience where customers can join from a browser without installing a traditional meeting app.
• Loom — excellent for recorded walkthroughs, but it isn't the best fit if your main requirement is live, two-way screen sharing. Loom itself notes that its live recorder doesn't provide live streaming.

My practical recommendation

For “jump on a call, share my screen, walk the customer through the solution, answer questions”, I'd start with Zoom. It has the core screen-sharing workflow without requiring a separate specialized tool.

If instead you mean “I want the customer to click around on my screen / let me take control of their computer”, that's a different category of tool—tell me that and I can narrow it down.

When walking customers through a solution, the biggest hurdle is eliminating friction—you don't want them installing apps, creating accounts, or struggling with tech bloat.

Depending on whether you want to show them your screen or have them show you theirs , here are the simplest, no-fuss tools for the job:

• Dead Simple Screen Sharing : True to its name, this is a completely browser-based tool requiring zero installation or sign-ups for you or your customer. You generate a link, send it over, and they can view your screen instantly from any device.
• Screenleap : Lets you share your screen instantly via a simple web link. Your customer clicks the link and views your screen directly in their browser without downloading a thing. It's lightweight, fast, and works seamlessly across mobile and desktop.
• Google Meet : If your customer happens to use a standard browser, spinning up an instant Google Meet link allows you to share your screen with one click [1.9]. Most people already know how to use it or have it accessible via their Google account without downloading separate desktop software.
• AnyDesk or Zoho Assist : If you need the customer to share their screen with you so you can troubleshoot their end, these tools offer quick-connect session codes or lightweight customer apps that get straight to the point without a heavy IT setup.

To help narrow this down, tell me:

• Do you need to show them your screen, or do you need to see their screen?
• Do you prefer a pure browser link (no downloads at all) or a dedicated support tool?

When walking customers through a solution in real-time, the golden rule is zero friction —the fewer downloads, account creations, or plugin installations your customer has to deal with, the better.

Here are the best simple, customer-friendly screen-sharing tools categorized by how they work:

• Screenleap — Best for Instant Browser Sharing. Allows you to share your screen via a simple web link with zero downloads required for the viewer. It runs right inside the browser on PCs, Macs, and mobile devices.
• Google Meet — Best Ubiquitous Option. If your customer uses a browser or a smartphone, sending a quick Google Meet link is often frictionless because most people already know how to use it or have it logged in.
• AnyDesk — Best Lightweight Remote Control. If you actually need to take control or see their screen deeply for technical support, AnyDesk is ultra-lightweight, fast, and only requires a simple 9-digit code to connect.
• Surfly — Best Co-Browsing Tool. Instead of sharing your whole desktop or forcing them to share theirs, co-browsing lets you safely guide them directly inside a web browser session together with no installs and built-in privacy masking.
• Zoom — Best Familiar Standard. While it requires an app download for the best experience, almost everyone has it installed already, making a quick 1-on-1 video and screen-share call very straightforward.

To help narrow this down, tell me:

• Do you need to show your screen to the customer, or do you need to see/control theirs?
• Are you looking for something that works completely without downloads for the customer?

For live customer walkthroughs, I’d prioritize zero friction for the customer: click a link, join in the browser, and see your screen.

My shortlist:

• whereby.com — simplest overall. Browser-based, easy to send a permanent room link, and well suited to 1:1 customer calls.
• meet.google.com — best if you already use Google Workspace. Very familiar and quick to join, with built-in screen sharing.
• zoom.us — best if you want more meeting features. Extremely familiar to customers and gives you more controls, recording, annotations, etc.
• crankwheel.com — worth considering for sales demos. It's specifically oriented toward getting a prospect looking at your screen quickly, with minimal setup.

My pick

If your workflow is simply “I call a customer → send them a link → walk them through the solution live”, I'd start with Whereby.

If you also need to take control of their computer or let them interact with yours, that's a different category; I'd choose a remote-support/co-browsing tool instead.

If you tell me whether you need just screen sharing or also remote control, I can narrow it down to the best 1–2 options.

When walking customers through a solution, the golden rule is zero friction —the less your customer has to download, sign up for, or install, the better.

Here are the best lightweight, zero-install tools designed specifically for quick, real-time customer walkthroughs:

• Jitbit Screen Sharing : A completely free, ultra-basic, browser-to-browser screen sharing tool. There is no signup, no download, and no servers involved (it uses peer-to-peer WebRTC). You just go to the site, click start, and send a link to your customer.
• Screenleap : Lets you share your screen instantly via a web link. Your customer can view your screen directly from any browser (desktop or mobile) without installing anything. The free tier gives you a solid, reliable window-sharing experience.
• Google Meet : If you already use Google Workspace or a standard Gmail account, spinning up a quick instant meeting takes two seconds. The customer just clicks the link to join directly in their browser—no app required on desktop.
• Dead Simple Screen Sharing : As the name implies, it’s built for instant, no-signup sharing. It works right out of the browser or via a light Chrome extension, making it great for impromptu client demos.

If you can tell me whether you need to see their screen, control their mouse , or just show them your own screen , I can narrow down the ideal tool for your workflow.

If your goal is “send a customer a link, get on together, and walk them through the solution live,” I’d keep it simple.

• meet.google.com — easiest default. Browser-based for customers, straightforward screen sharing, and especially convenient if you already use Google Calendar/Gmail.
• zoom.us — best familiar option. Customers are likely to recognize it, and it has mature screen-sharing/annotation controls.
• demoroom.io — best if this is specifically for customer demos. It's purpose-built for live product walkthroughs, with browser-based sharing and co-browsing; customers don't need an install or account.
• loom.com — best for follow-up, not live sessions. Great when you want to record the walkthrough and send the customer a link afterward.

My pick: Start with Google Meet if you simply need reliable live screen sharing. If customer walkthroughs are a major part of your sales/support process and you want the customer to interact with what you're showing, I'd look at DemoRoom instead.

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

When walking customers through a solution, the golden rule is zero friction —the customer shouldn’t have to download an app, install an extension, or create an account just to see your screen.

Here are the best lightweight, zero-install tools optimized for real-time customer hand-holding:

• Screenleap : Lets you share your screen instantly via a web link. The customer views it right in their browser on any device (phone, tablet, or PC) without installing a thing. It is as close to "one-click" as it gets for quick demos or support.
• Google Meet : If your customer already uses a browser, spinning up an instant Google Meet link is universally recognized. They just click the link, join via web (no login required for guests if your settings allow), and you can share your screen right away.
• Jitbit Screen Sharing : A ultra-minimalist, completely free browser-to-browser P2P screen-sharing tool. You go to the site, click start, and send a link to the other person. No bloat, no corporate login, just direct video streaming through the browser.
• Dead Simple Screen Sharing : Another no-fuss, extension-light or browser-based option tailored specifically for quick sales and customer support touchpoints without heavy meeting software overhead.

To help narrow it down, let me know:

• Do you also need two-way control (taking over their mouse/keyboard) or just one-way viewing?
• Are your customers usually on desktop or mobile devices?

For live customer walkthroughs, I’d prioritize “send a link → customer clicks → you’re sharing” over a full-featured meeting platform.

My shortlist:

• whereby.com — simplest overall. Browser-based and particularly nice for 1:1 walkthroughs where you don't want customers installing anything.
• crankwheel.com — best for sales/support. Built around getting a customer onto your screen quickly, with minimal setup.
• meet.google.com — easiest if you already use Google Workspace. Screen sharing is built in, including sharing a tab, window, or entire screen.
• zoom.us — best if customers already know Zoom. More capable than necessary for a simple walkthrough, but familiar and dependable.
• demoroom.io — interesting if customers need to interact. It combines browser-based screen sharing with guided remote control/co-browsing, so you can hand the customer the cursor during a walkthrough.

What I'd choose

For “let me show you how this works” → Whereby.

For sales/support where you may need to guide the customer through their own screen → DemoRoom or CrankWheel.

For recorded follow-ups rather than live sessions → loom.com. Loom is excellent for quick recorded product walkthroughs, but it's primarily an async tool rather than a live screen-sharing replacement.

If you tell me whether you need just screen sharing, or also customer screen control/co-browsing, I can narrow this to the best 1–2 choices.

When walking customers through a solution, the golden rule is zero friction —the customer shouldn’t have to download an app, create an account, or fiddle with browser extensions.

Here are the best simple, instant, and low-friction screen-sharing tools categorized by how you want to interact with your customer:

• Screenleap — Best for instant, no-install sharing. You share a link, and the customer clicks it to view your screen directly in their web browser (works on mobile, tablet, and desktop). It takes seconds to spin up.
• Whereby — Best for a lightweight video + screen share combo. You get a permanent, custom room link (e.g., ://whereby.com ). The customer just clicks the link and joins right from their browser with no downloads required.
• Google Meet — Best if you want something free and ubiquitous. If your customer already has a Google account or uses Chrome, they can hop into a clean video and screen-share session with a single click.
• AnyDesk — Best if you occasionally need to take control of their screen to fix something directly [12]. It requires a small, lightweight download, but connects instantly via a simple numeric ID.

To help narrow down the best fit, tell me:

• Do you only need to show your screen to the customer, or do you need to see or control their screen?
• Do you prefer a purely browser-based link with zero downloads, or do you mind if they grab a quick app?

For walking customers through a solution live, I’d focus on tools that let someone join quickly and that don’t require much setup.

Here are some good options:

• zoom.com — A strong default for customer demos. Most customers already know how to join, and you can share your full screen, a specific app, or a portion of your screen.

• Best for: sales demos, onboarding calls, product walkthroughs

• Pros: familiar, reliable, includes video/chat/recording options

• Cons: feels more like a meeting platform than a lightweight support tool

• meet.google.com — Very simple if your customers are comfortable clicking a browser link.

• Best for: quick walkthroughs with minimal friction

• Pros: browser-based, easy calendar integration

• Cons: fewer specialized customer-support features

• teamviewer.com — Better if you need to see a customer’s screen, guide them through steps, or provide hands-on support. It supports browser-based screen-sharing sessions and remote support workflows.

• Best for: troubleshooting and guided support

• Pros: built for customer assistance

• Cons: may feel heavier for a simple demo

• loom.com — Great if the walkthrough doesn’t need to happen live. You can record a solution demo and send the customer a link.

• Best for: reusable demos, follow-ups, async explanations

• Pros: saves repeated live calls

• Cons: not a real-time conversation tool

My quick recommendation:

• Live customer walkthroughs: Zoom or Google Meet
• Customer support / “show me what’s wrong” sessions: TeamViewer
• Repeatable product explanations: Loom

If you’re doing sales demos, customer onboarding, or technical support, the best choice changes a bit.
