New updates and improvements to CatDoes.
v4.0.0
Mar 26, 2026
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.

CatDoes v3.4.0
This update brings CatDoes Watch, Env Manager, and more!
New
CatDoes Watch: Projects built on CatDoes now benefit from a built-in error monitoring solution called CatDoes Watch, making it possible to see all the errors on all platforms during development and in production. You can then ask the agents to fix the errors for you.
Env Manager: You can now store your project's environment variables in an agentic and highly secure way, making it possible for the AI agents to read what environment variables are available in your project without giving away the values, and also for the AI agents to request filling required environment variables that your project needs.
Fork Projects: You can now fork your own projects, creating a copy of it that you can develop independently of the original project, making it possible to develop once and distribute using different brand and content.
