In the last month I have been working on Rust support for BrowserPod: you can now run any Rust CLI application in the browser, without changing any code! Here is a clip of OpenAI's Codex running in the browser:

BrowserPod is a WebAssembly code sandbox that can run Claude Code in the browser.

How is this possible, you might ask? Well, we just published a deep dive that explains it all.

In short: we wrote a WebAssembly-native kernel that runs in your tab.
