# jerrycan

> jerrycan is an AI-native, self-hostable Rust backend framework for building REST APIs — the real backend behind your SaaS. Your AI builds it; you own the code and data, run it anywhere, and scale it yourself, with no platform lock-in.

jerrycan is a backend framework (Rust) for REST APIs and application backends (auth, data, payments, security). It is AI-native: coding agents (Claude, Cursor, Copilot, and others) build the backend for you. Unlike managed backends such as Supabase or Firebase, the generated code and data are your IP — you own the backend behind your SaaS and can take it anywhere instead of renting it. It is free and open source.
