# FastAPI

FastAPI framework, high performance, easy to learn, fast to code, ready for production

## Getting started with FastAPI on Vercel

- [How to ship a FastAPI app on Vercel](/kb/guide/ship-a-fastapi-app-on-vercel): Deploy a FastAPI app to Vercel with zero configuration. Learn how the Python runtime, Vercel Functions, streaming, middleware, and cron jobs work together.
- [Build with a FastAPI starter template](/kb/guide/build-with-a-fastapi-starter-template): Browse FastAPI starter templates for Vercel and deploy one in a few steps. Compare minimal, AI, agent, and full-stack FastAPI templates on the Python runtime.
- [Build a Weather API on Vercel: Express, FastAPI, and Nitro](/kb/guide/weather-api-with-fastapi): Build a weather API on Vercel with FastAPI, Express, or Nitro. Compare the three runtimes, add caching and Observability, then deploy the route.
