Client feedback on the prototype. Your clients need no account.
Whatever builds your prototype, publish it here. Send your client one link that keeps working for every version: they comment anywhere in the UI without an account, and your agent ships the fix to the same link.
Your client work is tied to one tool. It belongs with you.
My client work lives in whichever tool built it.
Publish from any builder, including Claude Code, Codex, Cursor or Lovable: a static build as a folder, a zip or a single HTML file, or let your coding agent publish it. Every prototype gets the same viewer, one link that keeps working for every version and a place in your workspace, so the next tool you try changes nothing for your client.
Feedback arrives everywhere.
Email, chat, calls and screenshots. In critlab your client comments anywhere in the UI, each comment keeps a screenshot of what they saw, and it stays there until you resolve it.
Each client should see only their own work.
A folder per client keeps their prototypes and versions together, whichever tool built them. Share each prototype with Anyone with the link, a Password or Workspace members, and a client you invite as a guest sees only the folders you share with them.
There is no team to hand the fixes to.
Your coding agent is the team. It reads every open comment over MCP or the crit CLI, with what your client saw, publishes a new version to the same link and resolves the comments.
One link, from first draft to sign-off. Your agent ships the fixes.
Moves to the next tab every few seconds. Choose a tab to stop.
A terminal: crit publish puts the prototype online and prints its share link. Tina and Leo comment on two elements. Then, in Claude Code, the agent pulls both comments over MCP, commits the fix, publishes version 2 to the same link and resolves both comments.

Publish from your agent
One command, or ask your agent. The prototype gets a private, live link.
- 2
Send the link to your client
They open it in any browser. No account, nothing to install.
- 3
Your client comments anywhere in the UI
Each comment stays where they left it, with a screenshot and the screen size.

Your agent ships the fix
It reads the comments over MCP or the crit CLI, publishes a new version to the same link and resolves them.
What you get. For you and your clients.
Sharing, your way.
For your team and for guests: an open link, a password, or members only. Reviewers need no account.
Get feedback.
Press C and comment anywhere in the UI. Each comment comes with a screenshot of what the reviewer saw.
Collaboration workspace.
Folders per project or team, every prototype and its versions in one place for your whole team.
Built for agents.
Over MCP or the crit CLI, your agent publishes, reads what reviewers saw, and resolves.
Follow and Spotlight.
Present to a client with Spotlight and everyone follows your view. Or follow one person on your own.
Every version, one link.
Switch versions from the viewer's bar. Each comment stays with the version it was left on.
Desktop, tablet and mobile.
Switch the prototype between three screen sizes. Every comment shows the breakpoint it was left on.
Notifications.
Know when a reviewer comments and when your agent ships the fix. In the app, by email, or as a digest.
Whether you design or build. Your clients review the same way.
Product designers
Your prototype is the deliverable. Clients comment anywhere in the UI, on desktop, tablet or mobile, and every comment stays with the version it was left on.
Design engineers and developers
Your agent reads every open comment, with its CSS selector, the screen size and a screenshot, and ships the fix. Inspect, the files and the changes between versions are in the viewer, and you decide who sees the code.
