Deploy FastAPI

FastAPI is supported through a normal Mekong tunnel. Start the ASGI server locally, then expose the port.

If you want deeper Python-specific examples, also see the main FastAPI guide.

Basic flow

uvicorn main:app --host 0.0.0.0 --port 8000
mekong 8000

Works well for

FastAPI APIs
webhook receivers
backend services behind a deployed frontend
local development on real public URLs

Frontend + backend split

deploy the frontend build through /dashboard/deploy
run FastAPI locally or on your own server
expose the API with mekong 8000

Express / Fastify Go
