Can I use libraries like Pandas or NumPy?

While Workers have limited support for heavy data libraries via Pyodide, Cloudflare Containers are recommended for applications requiring full pandas/numpy support, native binaries, or GPU access.

When should I choose Containers over Workers?

Choose Workers for low-latency (<50ms) API endpoints and simple logic. Choose Containers for tasks requiring more than 10 seconds of compute, native Linux dependencies, or specific GPU resources.

How do I handle environment variables in this system?

Environment variables are defined in your wrangler.toml file and accessed within your Python code through the self.env attribute of the WorkerEntrypoint class.

How does Python run on Cloudflare Workers?

Python runs via Pyodide, which is CPython compiled to WebAssembly. This allows Python code to execute inside V8 isolates on Cloudflare's edge network with memory snapshotting for fast cold starts.

What is the best way to run FastAPI on Cloudflare?

This skill provides an ASGI adapter that allows you to wrap a standard FastAPI app and route edge fetch events directly into your application logic.
