How do I expose a FastAPI app to the internet?

Run `npx useburrow http 8000` alongside `uvicorn main:app --reload`. Burrow returns a public HTTPS URL that tunnels to your local server over an outbound WebSocket, so it works behind any firewall or NAT.

Do I need to allow the tunnel host?

FastAPI does not restrict hosts by default, so no extra config is needed. If you have added `TrustedHostMiddleware`, include your Burrow hostname (or `"*"` in development) in its `allowed_hosts`.

Where does my data go?

Through Burrow’s EU edge (Hetzner DE/FI). Request bodies stay on your machine unless you explicitly enable encrypted cloud history.

Tunnel your FastAPI localhost to a public URL

Tunnel your FastAPI localhost to a public URL | BurrowExpose your FastAPI server running on Uvicorn (localhost:8000) to a public HTTPS URL in one command. Test webhooks against your path operations, share your API and its docs, and inspect every request locally. EU-hosted, DSGVO-first.Burrow gives any local service a public, TLS-secured HTTPS URL with one command - npx useburrow http 3000 - hosted entirely in the EU. Webhook signatures are verified at the edge, every request is visible in the local inspector, and a first-class MCP server lets AI agents open and inspect tunnels.
