tl;dr: Cloudflare has moved Python Workers to general availability, making Python a first-class language on its Developer Platform with native support for bindings, Hyperdrive (PostgreSQL/MySQL), and popular frameworks like FastAPI, Django, and Flask via built-in WSGI/ASGI connectors. The team implemented WebAssembly socket syscalls using the Workers connect API, enabling HTTP clients and AI libraries like openai, langchain, and mcp to work natively. They also contributed PEP 783 (PyEmscripten) to standardize Python-on-WebAssembly package building across the broader ecosystem.
HN Discussion:
  • ~Cloudflare should financially support the upstream open-source projects (Pyodide, urllib3) they depend on
  • ↑Praise for Cloudflare's progress on Python Workers, especially package support and PEP 783
  • ↓This feels like a rehash of older platforms like Google App Engine
  • •Questions about practical performance concerns like WebAssembly cold-start times
  • •Desire for similar first-class support for other languages (Go, Mojo, Elixir)
