CatDoes v4.1.0

CatDoes builds websites now. And you can bring your own from GitHub.

New
  • Websites - The agent can now build websites, not just mobile apps. Same agent, same workflow.

  • GitHub Import - Bring any GitHub repo into CatDoes as a project and keep building with the agent.

  • Custom Domains - Connect your own domain to any web deployment.

  • Monorepos - A single project can now hold a mobile app and a website together (or multiple of each). The agent works across them.

  • Preview Size Switcher - See your app preview in iPhone 15, iPhone SE, Pixel 8, iPad, laptop, and other device sizes.

  • Context Window Indicator - A small button that shows how full the agent's context window is when you hover it.

Improvements
  • General UI and UX improvements across the dashboard

  • PWA improvements

  • General platform stability improvements

Fixes
  • Fixed a bug where downgrading your plan would sometimes fail

  • Fixed a bug where the agent would stop mid-task

CatDoes v4.0.0

Your app now gets a real backend, and the agent runs in the cloud.

New
  • CatDoes Cloud - Database, auth, file storage, edge functions, real-time events. All included, all plans. US and EU regions.

  • Compose Agent - New agent that runs in the cloud. Close your browser, it keeps going. Compose can spin up subagents to work on different parts of your request at the same time. It also has its own computer, so it can do things the previous agent couldn't (install packages, run scripts, test builds).

  • File Browser - You can now browse your app's code and edit files directly from the dashboard.

  • Website to Mobile App - Paste any URL (Lovable, WordPress, Shopify, whatever) and the agent turns it into a mobile app.

  • Multi-page Canvas - See all your pages at once in an interactive canvas view.

  • Secure Input - When the agent needs an API key or password, it collects it through an encrypted field. The AI never sees the actual value.

  • Screenshot Tool - Screenshot the app preview, crop and draw on it, attach it to your message. Good for pointing out UI problems.

  • Error Notifications - App errors now pop up as notifications with a "Fix with AI" button. If the agent is already working, the fix gets queued.

  • Completion Sounds - You'll hear a sound when the agent finishes or needs your input, even from another tab. Different sounds for different events. You can turn it off in Settings.

  • Explore - A page with public projects you can fork and make your own.

  • Sound Assets - Import sounds from the asset manager into your project.

  • AGENTS.md - New projects ship with an AGENTS.md file. Compose keeps it updated as you build.

  • PWA - Install CatDoes as an app on your phone or desktop.

Improvements
  • Lots of UI and UX improvements throughout the dashboard

  • Junior agent has better design taste, still at 0.3x credit cost

  • Agents use fewer credits
