Run Ostrin

The real compiler, built to WebAssembly (wasm32-wasip1), running the interpreter locally in this page. Nothing is uploaded.

Run executes the interpreter. Native C compilation needs a C toolchain, so it is not available in the browser. Programs see a single in-memory file and no network.
