WRITE IT · RUN IT · SHARE IT

Your dev environment is now a URL.

a real IDE that opens like a new tab — no install, nothing to configure

main.py
# press run to execute this in your browser

// no setup

It runs where you opened it.

Nothing to install, nothing to configure. Open a tab and you already have an editor, a live preview, and a run button — press it and the output shows up right there. The languages you actually use are ready to go:

try it in the IDE
languages
PythonJavaScriptHTML / CSSCC++Java

// edit together

Two people, one file.

Share a project and edit it together — you see each other’s cursors and every keystroke as it happens. Same file, same output, no waiting to sync. That’s ana editing on the right; click into the code and type alongside her, or open the full demo:

// share it

Every project is a URL.

Press share and you get a link. Drop it in a message, a pull request, a class assignment — whoever opens it lands in the same workspace, running code included.
