Python in Cloudflare Workers – Running Pyodide on the Edge

on YouTube ↗01h 01m

" summary

Deploys Pyodide in Cloudflare Python Workers Beta to run Python serverless at the edge, using Cloudflare D1 database, object storage and Workers AI (Llama 3) for a pet‑voting demo that works live. Cold starts drop via memory snapshots, package installs go from ~30s to under 1s by serving preprocessed wheels, and async sync gaps close with stack switching and improved FFI; bundles constrained to ~1MB free and 10MB paid.
