// About CodeLabs

Built by developers, for the way developers actually work.

CodeLabs started as a side project: a real CodePen-style playground that also runs C# and SQL. Built by a developer and teacher in Croatia to make code easy to write, run, and share together.

Our story

In 2023, I wanted to share a quick C# snippet with a colleague the way I'd share a CodePen. Nothing existed. Sandboxes were either too heavy (full IDEs) or too narrow (browser-only). So I built one, and kept building.

Today CodeLabs runs three first-class editors with the same look, the same shortcuts, and the same real-time collab. One playground. Any stack.

What we believe

Speed is a feature.

Press Run. See output. The loop should be sub-second.

Collaboration shouldn't need installing things.

A URL is enough.

Your code is yours.

Export anytime, no lock-in, no buried buttons.
