Cloudflare Python Workers are now generally available
Cloudflare's support for running Python in its server-side Workers platform is now generally available after a two-year preview, according to Simon Willison. Cloudflare describes Python as a first-class, fully supported language on its Developer Platform. Python runs compiled to WebAssembly via Pyodide inside Cloudflare's V8-based workerd runtime, which the source notes leaves multiprocessing and threading non-functional in the WebAssembly VM. The local tool pywrangler, packaged as workers-py on PyPI, simulates the stack locally.
Developers can now run Python on Cloudflare Workers as a stable, supported language, though threading and multiprocessing remain unavailable in the WebAssembly VM.
