Phyll CloudbetaOpen source

UX review for apps built with AI, inside the agent you already use

Phyll runs in your Codex or Claude Code, on your own plan. It opens your app the way a first-time user would, shows what gets in the way and fixes it without touching your design.

How it works

  1. Create your account below, or run npx phyll signup you@example.com
  2. Connect Phyll to your agent: 
    npx phyll setup codex    # or: npx phyll setup claude
  3. Ask your agent to review the app, for example: review my app at http://localhost:3000.
