Render raises $100M at a $1.5B valuation
Read the announcementWhy deploy FastAPI on Render?
FastAPI is a modern Python web framework for building APIs. It provides automatic data validation, serialization, and interactive API documentation, enabling developers to build production-ready APIs quickly with less boilerplate code.
This template gives you a production-ready FastAPI service with the correct Uvicorn start command and Python dependency detection already configured—no fumbling with port bindings or WSGI/ASGI setup. One click deploys the entire service with Render's automatic Python environment detection, so you skip the manual web service configuration steps entirely. You also get instant access to Render's preview environments for testing branches before merging, something that would require significant extra tooling to replicate yourself.
Architecture
What you can build
After deploying, you'll have a live FastAPI web service running on a public URL, ready to accept HTTP requests. The template includes a basic app structure you can immediately start modifying to build out your API endpoints. You can push changes to your repo and Render will automatically redeploy.
Key features
- One-click deployment: Deploy to Render instantly using the deploy button without manual configuration.
- Uvicorn ASGI server: Pre-configured to run FastAPI with Uvicorn using dynamic port binding for production.
- Auto dependency detection: Render automatically detects Python and installs dependencies via pip from requirements.
- Template repository: Fork and customize the boilerplate code as a starting point for your own FastAPI projects.
Use cases
- Backend developer deploys a REST API prototype without managing servers
- Startup founder launches MVP backend endpoint in minutes
- Data scientist hosts a model prediction API for team access
- Freelancer quickly ships client API with automatic Python dependency handling
Next steps
- Open your service URL with /docs appended — You should see the FastAPI interactive Swagger UI documentation page load with your API endpoints listed
- Test the root endpoint by clicking 'Try it out' on the GET / route in the Swagger UI — You should receive a JSON response with a 200 status code confirming the API is responding
- Configure a custom domain in your Render dashboard under Settings > Custom Domains — You should see the domain status change to 'Verified' and your API accessible at the new URL
