What it is
A collaborative coding environment where teams write and run code together in real time. Built-in compiler, multi-language support, no setup required — just share a link and start.
Why I built it
Interview prep with friends kept hitting the same wall: someone has to spin up a sandbox, share a screen, paste code into Slack. Pair Code is the inverse — you get a URL, both of you type, both of you run, the cursor positions sync.
What's inside
- WebSockets for cursor + edit sync across clients.
- Sandboxed compiler runs submitted code on a server worker pool.
- Multi-language support — JS, Python, C++, more.
- Just-share-a-link flow; no accounts required for ad-hoc sessions.
