Fabro runs as a server. This quickstart runs everything locally on your laptop — no deployment required. To self-host the server for a team or 24/7 workflows, see Deployment.

Release binaries and the multi-arch Docker image ship with SLSA Build Provenance attestations you can verify with gh attestation verify.
Self-hosting the server? See Self-host with Docker and Server Operations for the install wizard, auth, and CLI-pointing.

​
Initialize your project

cd my-repo/
fabro repo init
This creates .fabro/project.toml and a starter workflow under .fabro/workflows/hello/.

​
Configure API keys

Add at least one LLM provider key: 
ANTHROPIC_API_KEY=sk-ant-...
OPENAI_API_KEY=sk-...
GEMINI_API_KEY=AI...
You only need one provider key to get started. Add more to enable multi-model workflows.

​
Run your first workflow

fabro run hello
