jerrycan

The AI-native Rust backend platform.

jerrycan is two inseparable halves shipped as one crate:

1. A backend framework — a ground-up rewrite of the Flask/Werkzeug concept space in Rust: a lean core, async-only on tokio + hyper, trait-based extensions (db, auth, validate, observe), secure by default.
2. A generation platform — one jerrycan binary that is both a CLI and an MCP server, through which AI agents design → generate test-first → verify → package complete, deployable backends.

Install

The intended path: point your coding agent at jerrycan with one line. It installs the CLI, wires jerrycan into the agent (MCP), and leaves a guided runbook behind:

curl -fsSL https://jerrycan.cc/install.sh | bash -s -- --agent claude-code

Agent ids: claude-code · cursor · codex · windsurf · generic.

Prefer to install the CLI / MCP server directly:

cargo binstall jerrycan   # prebuilt binaries
cargo install jerrycan    # or build from source

Or add the framework to a Rust app:

cargo add jerrycan --features db,auth,validate,observe
