Cloudflare has officially launched its Python Workers service, with Python now becoming a core language for its developer platform. It seamlessly integrates with the platform's full range of services and directly supports running mainstream Python Web frameworks such as FastAPI, Django, and Flask. Based on Cloudflare's existing WebAssembly technology and integrating the Python interpreter compiled by Pyodide Wasm, developers do not need to adjust their development approach or refactor code for the edge platform. The official version released this time optimizes the development experience by eliminating the need for manually written type conversion code. The relevant logic has been encapsulated in the runtime environment and Python SDK, allowing developers to directly call platform services without interacting with JavaScript. The service is compatible with WSGI and ASGI standards in the Python ecosystem through a lightweight bridging layer, with Cloudflare's platform handling Web server functions uniformly, including load balancing and automatic scaling. Addressing the lack of TCP sockets due to WebAssembly sandbox environment limitations, Cloudflare has achieved a breakthrough through Hyperdrive technology, enabling Python Workers to run database drivers such as asyncpg and aiomysql smoothly, providing full support for relational database operations. Developers can directly use familiar Python frameworks to develop APIs and integrate with platform services, without needing to configure server infrastructure themselves throughout the process.
