Cloudflare has launched Python support in the Workers platform

Company Cloudflare has officially opened access to Python Workers. Now developers can run Python code directly in the platform's infrastructure without the need for pre-compilation into WebAssembly.

The new functionality allows using popular frameworks, including FastAPI and Django, to create server-side applications. The integration provides native support for all system bindings and platform services, such as KV, Durable Objects, R2, and D1. Deployment is carried out through the standard Wrangler command-line interface.

A specialized runtime environment is used to work with Python code, which minimizes delays during cold starts. Developers can connect third-party libraries via the PyPI package manager, while the system automatically handles dependencies during the project build process. Support includes working with asynchronous functions, which is critical for high-load network services.

Switching to Python in Workers eliminates the need for intermediate code translation layers, simplifying the migration of existing backend solutions to Cloudflare's server architecture. The tool is focused on creating scalable APIs and microservices that operate at the network edge with minimal access latency for end-users.
