Everything that runs in the tab
One kernel routes each program to the runner that fits it: a RISC-V VM for real Linux ELF binaries, Node on the browser's JS engine, a wasm runner for wasm32-wasip1 apps, and the Boa interpreter for untrusted JavaScript. Every page below has samples you can run right here — nothing downloads until you press Run.
