Run FastAPI Locally with FlyEnv
FastAPI applications typically need a Python runtime plus the database and supporting services chosen by the API. FlyEnv helps manage those services around a local FastAPI project.

About FastAPI
FastAPI is a Python framework for building typed HTTP APIs. Type hints drive validation, serialization, dependency injection, and OpenAPI documentation, while its ASGI foundation supports asynchronous endpoints and WebSockets.
A local FastAPI service is usually run through an ASGI server such as Uvicorn. The rest of the environment should follow the service itself: an ORM-backed database for durable data, migrations, and optional worker or broker processes for asynchronous workloads.
Core capabilities
- Type-driven Validation
- OpenAPI Documentation
- Dependency Injection
- Async ASGI Endpoints
- WebSockets
- Pydantic Models
Common use cases
- Typed REST APIs
- Backend services for mobile applications
- Data and ML service endpoints
- Async integration APIs
- Internal API platforms
A FastAPI environment follows the service contract
The framework itself is deliberately small, so local dependencies should reflect the API implementation rather than a preset stack.
- Python and ASGI server
- Run the application with its locked Python dependencies and an ASGI server such as Uvicorn.
- Database and migrations
- PostgreSQL or another selected database is paired with the project ORM and migration tool.
- API clients and secure origin
- A local domain and HTTPS can matter for browser clients, OAuth redirects, or webhook callback testing.
- Broker and workers when designed in
- Redis, RabbitMQ, or a worker process belongs only where the API explicitly offloads background work.
Project resources
For installation commands, supported versions, and project-specific configuration, refer to the official FastAPI documentation.
Typical local stack
The exact services depend on the project, its release, and its local configuration. This is a common local setup, not a fixed requirement.
How FlyEnv helps
Manage Python versions
Match the runtime version to the project requirements.
Run API data services
Start the database selected by the application.
Add Redis by configuration
Keep Redis available for services that use it.
Serve local endpoints
Use a local domain and HTTPS for browser or client integration.
Set up the local environment
Project installation stays with the upstream documentation. FlyEnv manages the runtimes, databases, web servers, and supporting services around it.
- 1Use the FastAPI documentation for application installation and dependency setup.
- 2Select the Python runtime required by the application.
- 3Start the configured database service.
- 4Start Redis or another supporting service only when the project uses it.
- 5Configure a local domain, reverse proxy, and HTTPS when the API needs them.
- 6Keep the API and supporting services in a Startup Group when helpful.
