Where ideas take shape
Linea is the collaborative whiteboard for fast-moving teams. Sketch, point, and decide together in real time, right in your browser.
Built with Next.js, WebSockets, and PostgreSQL
Made for thinking together
Real-time cursors
Every pointer is live. Watch teammates sketch, point, and react the moment it happens, like standing at the same whiteboard.
Infinite canvas
Zoom out and the board keeps going. Architecture diagrams, sprint boards, and scribbles all live in one endless space.
Hand-drawn feel
Strokes with personality, not pixel-perfect noise. Rough edges keep ideas feeling early, so people keep iterating.
From blank to decided in minutes
Create a board
One click, no setup. A fresh canvas with a dot grid and your team's name on it.
Share the link
Teammates open the link, sign in, and land on your canvas. Everyone sees the same board, live.
Think out loud
Sketch flows, drag cards, drop comments, and vote. Decisions happen on the board, not in a thread.
Every stroke, replayed
Linea records every action on an append-only operation log. Scrub back to any moment and watch the board rebuild itself, stroke by stroke.
- Undo that never lies, even mid-collaboration
- Jump to any point in the board's history
- Watch how a decision actually happened
One canvas, every ritual
Good ones, answered
Do I need an account?
How does time travel work?
Does it work on tablets and phones?
Is Linea open source?
Ready to think out loud
Spin up a board and invite your team. It takes less time than reading this sentence.
