A real-time collaborative workspace built for developers. Create a room, share the link, and write code, markdown, and diagrams together — live.
Write together in real time. Every keystroke is synced instantly. No refresh, no merge conflicts — just you and your collaborators in the same document.
Tabs for every type of work. Each room supports multiple tabs. Pick the right surface for the job:
- Markdown — write docs, notes, or specs with a live rendered preview side by side. Full toolbar for formatting, syntax-highlighted code blocks.
- Code — a shared code editor with syntax highlighting across 150+ languages. Switch languages on the fly.
- Drawing — a collaborative infinite canvas powered by tldraw. Sketch diagrams, wireframes, or whatever you need. Grid and background settings sync across all users.
Flexible access control. Two room types, full control over who can see and edit:
| Open | Private | |
|---|---|---|
| Who can join | Anyone with the link | Whitelisted emails only |
| Managing access | — | Add/remove emails via whitelist and blacklist |
| Guests (no account) | Sign-in required by default | Sign-in required by default |
| Guest override | Allow guests to view or edit | Allow guests to view or edit |
Three-tier roles.
- Owner — full control: rename, delete, transfer ownership, manage roles, manage whitelist/blacklist, change visibility
- Admin — create/delete/reorder tabs, kick members, manage whitelist/blacklist
- Member — edit tab content only
Live presence. See who's in the room with you via overlapping avatars in the top bar. Every user gets a unique color.
Notifications. Bell icon shows when someone grants you access to a room or accepts your invitation. Email notifications with one-click unsubscribe.
