Pastel and Yocoolab both let people comment on a live website. Pastel layers comments on your site through its own proxy. Yocoolab runs as a browser extension on the page you already have open, including localhost and staging, and its threads go to your coding agent with the element, selector and screenshot attached.
Free in beta for your whole team.
From Pastel’s own site. Pastel has a free plan, free reviewers and an MCP server for agents, so the difference is in how each tool works, not in whether it does.
Both put comments on the live site and both work with agents. They attach, and close the loop, differently.

Install the extension for Chrome, Edge or Firefox, pin feedback on any live page, and send it to your coding agent. Free in beta for your whole team, no credit card.
Straight answers, including where another tool is still the better choice.
Yes. A project owner can share a guest link; a guest joins with a name and email, no password, and can start threads and reply. Teammates you invite are free in beta too. Pastel also lets reviewers comment without logging in, so this is not a difference between the two.
It works on the live web pages you point it at, because it runs in the browser rather than inside your codebase. Teams typically use it on their own staging and production URLs, and on preview deployments during review.
Threads carry a workflow stage, so a round of feedback can move from raised to in progress to in review without being retyped somewhere else. When a change is needed, the thread itself can be sent to a coding agent with the context attached.
Yes, and plenty of teams should. Pastel keeps doing what it is good at, and Yocoolab handles the part that happens on the running product — pinning feedback to a real element, keeping the discussion attached to it, and handing that context to a coding agent. Yocoolab is a browser extension, so it sits on top of your app without you migrating anything.
No. In beta the app is free, including for everyone you invite to look at or comment on work. We have not set pricing for after beta and will give clear notice before anything changes.
Install the browser extension for Chrome, Edge or Firefox, sign in with Google, GitHub or email, and open the page you want feedback on. There is nothing to embed and no code change to your app. Connecting a coding agent is one more step: give it the address https://app.yocoolab.com/mcp and sign in to Yocoolab when it asks. There is nothing to install and no token to paste.
