For agencies

One workspace for every client. Each client sees only their own work.

A folder per client and a link per prototype. Clients comment anywhere in the UI, and your agents ship the fixes to the same link.

Why critlab

Many clients, many prototypes. One place to find them, and their feedback.

  • In Figma, every client had a project. Now each prototype lives on its builder's own link.

    It is in that client's folder, with a thumbnail, its status and every version on the same link. ⌘K finds any prototype or comment, and when a project ends, archive the folder: its share links keep working.

  • Every client's feedback lives somewhere else.

    Email, calls, chat and annotated screenshots. In critlab clients comment anywhere in the UI, each comment keeps a screenshot of what they saw, and it stays in that client's folder.

  • One client must never see another client's work.

    Give each client a folder. Invite their team as guests and they see only the folders you share with them. Or share a single prototype with Anyone with the link or a Password.

  • The brief is buried in someone's inbox.

    Keep the brief, the tickets and the research on the client's folder, as links, PDFs or Markdown. Your team and your agents read them next to the prototype, and a guest sees them only if you allow it.

How it works

From kickoff to sign-off. Every round on the same link.

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.

  1. 1

    Set up a folder for the client

    Their prototypes, versions and context live there. Give it a colour or an image so it stands out.

  2. 2

    Publish from your agent

    One command, or ask your agent. Each prototype gets a private, live link.

  3. 3

    Share it your way

    With Anyone with the link, a Password, or the client's team as guests who see only their folder.

  4. 4

    Ship each round to the same link

    Your agent reads the comments over MCP or the crit CLI, publishes a new version and resolves them. Each comment stays with its version.

Features

What your studio gets. For your team and every client.

  • Collaboration workspace.

    Folders per project or team, every prototype and its versions in one place for your whole team.

  • Sharing, your way.

    For your team and for guests: an open link, a password, or members only. Reviewers need no account.

  • Roles and guest access.

    Owner, admin, member and guest. Guests see only the folders you share with them.

  • Get feedback.

    Press C and comment anywhere in the UI. Each comment comes with a screenshot of what the reviewer saw.

  • 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.

  • Built for agents.

    Over MCP or the crit CLI, your agent publishes, reads what reviewers saw, and resolves.

Questions

Anything else? Write to us at support@critlab.app

  • Not to comment. Share a prototype with Anyone with the link, or add a Password, and they comment in any browser. Invite a client's team as guests when they should see a whole folder.

  • No. A guest sees only the folders you share with them, and every prototype has its own link and its own access setting.

  • Yes. Choose Spotlight me in the viewer and everyone in the prototype follows your view, live, including the device view you switch to.

  • Yes. Custom share domains are available on request. Talk to us.

  • Archive the client's folder. It leaves your everyday view with everything in it, and its share links keep working. Unarchive it and it is all back where it was.

  • No. Prototypes are never indexed, and every version runs on its own isolated origin.

Bring your next client in. A folder, a link and feedback your agent can act on.
