With the new experimental support for the Emscripten target in Rust Workers, many previously unsupported Rust libraries and applications can now be built and deployed directly to Cloudflare’s global Workers platform, including upcoming support for Tokio async.
Python Workers allow developers to run Python web frameworks and AI orchestration libraries natively in the Cloudflare Workers runtime. You can seamlessly integrate with Cloudflare's ecosystem including D1, R2, and Workers AI without writing any JavaScript glue code.
Panics in Rust Workers were historically fatal, poisoning the entire instance. By collaborating upstream on the wasm‑bindgen project, Rust Workers now support resilient critical error recovery, including panic unwinding using WebAssembly Exception Handling.
Introducing Cloudflare Workers in Python, now in open beta! We've revamped our systems to support Python, from the runtime to deployment. Learn about Python Worker's lifecycle, dynamic linking, and memory snapshots in this post
Debugging Rust and Wasm with Cloudflare Workers involves a lot of the good old time-consuming and nerve-wracking printf'ing strategy. What if there’s a better way? This blog is about enabling and using Wasm core dumps and how you can easily debug Rust in Cloudflare Workers
After the recent announcement regarding WASI support in Workers I decided to see what it would take to get code written in Zig to run as a Worker, and it turned out to be pretty trivial. This post documents the process I followed
Today, we are announcing experimental support for WASI (the WebAssembly System Interface) on Cloudflare Workers and support within wrangler2 to make it a joy to work with
