Instead of pasting it in Slack:
Send a link.
A real-time collaborative code pad. 40+ languages, multiple files per pad, live cursors. No accounts, no setup.
Live cursors
Labeled carets and tinted selections on a real CodeMirror buffer, not a textarea in disguise.

Do I need an account to use Codepad?
No. Click "+ new pad" and you get a shareable URL instantly. Your collaborator opens the same link, no signup either.
Is Codepad free?
Yes. Codepad is free to use, with no plan upgrades and no seat counts.
How is Codepad different from Google Docs?
Codepad gives you the same "send the link" ergonomics as Google Docs, but with a real code editor underneath: syntax highlighting for 40+ languages, line numbers, bracket matching, multiple files per pad, and a private notes panel.
Can I share code without signing up?
Yes. Type into the editor on the homepage and hit share. Codepad creates the pad and gives you a URL you can send to anyone. Neither of you needs an account, and whoever opens the link can edit alongside you straight away.
How many people can edit a pad at the same time?
Multiple peers can edit a pad simultaneously. Cursors and selections sync in real time using Yjs CRDT, so concurrent edits never conflict.
