Online Rust Compiler — write, compile & run Rust

Rust compiles to a native binary with rustc/Cargo — not a browser task. The server compiles your fn main() and runs it, returning println! output and any of Rust's famously detailed compiler messages.

When you press Run, your Rust code is sent to a sandboxed execution service that compiles and runs it in an isolated environment, then returns the output. It does notrun on induwara.lk's servers — our site only proxies the request, so your code can never touch our systems, files, or other users. Languages like Rustneed a real compiler/runtime, which isn't practical in a browser, so this is the safe way to offer them.

The proxy is strictly bounded: a 30-second execution limit, a 50 KB code cap, and per-IP plus global rate limits that protect the shared compiler. There's no signup and nothing to install — write code, hit Run, read the output.

• Wandbox — the sandboxed compiler service used to run your code

Compilation + execution happen on Wandbox's isolated servers; induwara.lk only proxies the request with rate limits and caps.
