Our Commentary ​

Python on Cloudflare Workers, finally GA! This is a big deal for Pythonistas who want to dabble in edge computing without learning JavaScript. The WebAssembly/Pyodide approach is super clever, even with the threading limitations. I'm always impressed by how Cloudflare pushes the boundaries of what's possible at the edge. It makes me wonder if we'll see more languages become first-class citizens on these platforms, further blurring the lines between traditional backend and frontend development.
