fal
fal is a serverless Python runtime that lets you run and scale code in the cloud with no infra management.
With fal, you can build pipelines, serve ML models and scale them up to many users. You scale down to 0 when you don't use any resources.
For full product and platform documentation, see fal.ai/docs.
For connection-oriented WebRTC apps, see the fal.wma guide and CPU echo example.
Quickstart
Install the package and authenticate:
pip install fal
fal auth login
Create a minimal app:
import fal
class MyApp(fal.App):
@fal.endpoint("/")
def run(self) -> dict:
return {"message": "Hello, World!"}
Run it on fal for testing:
fal run hello_world.py::MyApp
Deploy it to a persistent endpoint:
fal deploy hello_world.py::MyApp
