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.

Works with what you build with

Multiplayer

Review together, live. Your team and your stakeholders in the same prototype.

Enterprise & self-hosted

Ready for your security review. Or run it on your own servers.

Sign-in through your identity provider, access you can audit, and data that stays where you put it.

Features

What your team gets. From agents to enterprise.

  • Built for agents.

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

  • 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.

  • Get feedback.

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

  • Replies, reactions, resolve.

    Reviewers talk it through: your agent replies, reacts when it's on it, and resolves once shipped.

  • Live presence and Spotlight.

    See who's here and where their cursor is. Present to a client, and the room follows along.

  • Notifications.

    Know when a reviewer comments and when your agent ships the fix. In the app, by email, or as a digest.

  • Your staging site, too.

    One script tag brings the same comments to a site you already host.

  • Single sign-on and SCIM.

    SAML routes sign-in to your identity provider by email domain, with directory sync.

  • Audit log.

    Every action on record. Filter by person, folder or prototype, and export CSV or JSON.

  • Your storage, your region.

    Bring your own S3-compatible bucket, with EU region pinning.

  • Self-hosted.

    The same codebase on your own servers. Docker Compose or Helm, air-gapped if you need it.

Give every prototype a home.
