Cloudflare Workers now generally available for Python applications
Key points
- Python Workers are now generally available on Cloudflare.
- Python is a first-class, fully supported language in Workers runtime.
- Supports integration with Cloudflare services like AI, R2, D1.
- Popular Python frameworks like FastAPI, Django, Flask are supported.
Python Workers Reach General Availability
Cloudflare has officially announced the general availability (GA) of Python Workers. This means that Python is now a fully supported language within the Cloudflare Developer Platform, allowing developers to deploy Python applications directly to the Workers runtime. The feature was initially introduced two years ago and has now reached a production-ready state.
Enhanced Platform Integration
With GA status, Python Workers offer native support for Cloudflare Developer Platform bindings. This enables seamless integration with other Cloudflare services such as Workers AI, R2, D1, Hyperdrive, Durable Objects, and Queues. Developers can utilize their existing Python code, libraries, and design patterns within this environment.
Framework Compatibility and Development
The general availability includes support for popular Python web frameworks like FastAPI, Django, and Flask, which can now run inside Python Workers. The development of Python Workers leveraged WebAssembly (Wasm) and Pyodide, allowing a Wasm-compiled Python interpreter to run within the Workers environment. This multi-year effort aimed to create a scalable platform for Python applications with ease of development and performance comparable to other Python environments.
