How it works
Server-side languages (Python, Java, Rust, etc.) run on a free public sandbox, your code is sent to a Piston container, executed, and the output is returned. No setup, no installs. HTML/CSS/JS renders directly in your browser inside a sandboxed iframe, instant preview, no server round-trip.
