Python Workers redux: fast cold starts, packages, and a uv-first workflow

The report announces Cloudflare’s enhanced Python Workers, now supporting Pyodide-backed package installations with uv/pywrangler tooling, and details major cold-start performance gains via memory snapshots and request sharding, outperforming AWS Lambda and Google Cloud Run in benchmarks. It explains technical approaches for snapshotting (entropy handling, WebAssembly state, dynamic libraries, and JS references), provides deployment examples (e.g., FastAPI), and highlights roadmap items such as improved tooling, faster cold starts, broader package support, and native socket/WebSocket capabilities.
