Online Ruby compiler. Run Ruby instantly.

Free online Ruby compiler and interpreter. Write Ruby, run it instantly in your browser, see the output, and share a live, editable link. No install needed.

No rbenv, no gems, no setup. Write Ruby and press Run.

The short answer

SnIPPETsX is a free online Ruby compiler and interpreter. Choose Ruby, write or paste a script and press Run to execute it in an isolated sandbox; puts output and exceptions appear below the editor. Nothing needs installing, and the script is shareable by URL with real-time co-editing.

  • Ruby scripts execute server-side with the standard library.
  • Shared links open a live, editable session.

Quick Ruby experiments, shareable by link

Ruby is great for quick experiments — trying an Enumerable chain, a string method or a block idiom — but setting up rbenv or rvm just to test one is overkill. SnIPPETsX runs Ruby scripts in a sandbox the moment you press Run.

Share the link with a teammate or student and they join the same session with live cursors, so you can walk through Ruby idioms together. Gems are not installed; the standard library is available.

Key features

  • Instant Ruby — Run Ruby scripts with no version manager or install.
  • Readable Errors — Exceptions and backtraces exactly as Ruby prints them.
  • Teach Live — Share a link and walk through Ruby idioms together.
