CatDoes

CatDoes is an AI agent, not just a code generator, that builds mobile apps and websites from a plain-english description. Its agent (nicknamed Compose) runs in the cloud on its own machine: it plans the work, writes the code, runs tests, and fixes its own errors, so you can close the tab and come back once it's done. Every project ships with a backend included (database, auth, storage, edge functions) instead of a separate setup step. It also has a distinct trick: paste a URL from Lovable, WordPress, Shopify, or elsewhere, and it builds a matching native mobile app.

Who it's for Startup founders and business owners who want an app or internal tool without a dev queue, designers turning Figma prototypes into working products, and non-technical people with an app idea they've never had time to build. Engineers can also import a GitHub repo and use it to move faster rather than starting from scratch.
