When Simon Willison tried Cloudflare’s local Python development setup on September 21, he found a 123MB workerd binary inside his project’s installed modules. The programmer traced what it contained: Pyodide running Python as WebAssembly inside V8, the JavaScript engine that also powers Chrome. Inspecting that local copy mattered because it showed developers were testing against a simulation of the server runtime.
The same runtime now has a production role in applications built with Python.
On September 21, Cloudflare made Python Workers generally available after a two-year preview. Developers can put familiar Python web applications and AI coordination code on Cloudflare’s managed network, joining a contest for the storage, job processing and model usage that often accumulate around the first deployed function.
