ship it

// why cout

Everything you need to code with someone else.

Live multiplayer

See every teammate's cursor and selection as they move. Edit the same file at once — conflict-free, powered by CRDTs.

Instant execution

Run Python & C++ and get real stdout, stderr and exit codes back in milliseconds. Pass stdin, see compile errors.

Sandboxed & safe

Every run is isolated: no network, capped CPU and memory, torn down after each execution. Nothing touches the host.

Zero setup

No installs, no accounts, no package managers. Share a link and you're writing code together in seconds.

// how it works

Three steps to coding together.

01

Create a room

One click spins up a private room with its own shareable code.

02

Share the link

Teammates join straight from the browser — no accounts needed.

03

Code & run

Edit side by side and execute Python or C++ whenever you like.

Start a room. Send the link.

Free while in beta. No account, no setup — just code.
