Draw on a collaborative whiteboard between browsers
Use a collaborative whiteboard between two browsers by exchanging WebRTC connection codes. Drawings sync while both pages stay open. Free to use, with no sign-up required.
Files processed on your deviceConnect
Data goes straight between browsers over an encrypted WebRTC channel. A public STUN server only helps the browsers find each other; it never sees your files. Some strict office networks block direct connections.

Draw now — it syncs when someone joinsThe host relays drawing between everyone connected. Undo removes your own last stroke.
01 How it works
- Open this page in two browsers and exchange connection codes.
- Draw on either board.
- See the strokes appear in both browsers.
02 Good to know
The board connects one pair of browsers with WebRTC. Each side must keep the page open. It does not save a session or support multiple participants.
03Pair two browsers and draw
Open the whiteboard in both browsers and exchange the connection codes. Once connected, draw on either board and the strokes sync to the other browser.
The tool connects one pair of browsers. Each person needs to keep the page open during the session. It does not support a larger group or save the board for a later visit.
04Plan for a live session
Network restrictions can prevent a direct connection, and the board has no relay fallback. If the pages do not connect, retry on a network that allows peer-to-peer WebRTC.
Save or capture any work you need to keep before closing the pages. Reopening the tool starts without the previous board state.
05 Questions
Can more than two people use the board?
No. The current board connects a pair of browsers.
Will the board be there when I return?
No. The board is not saved as a persistent session. Keep both pages open and capture work you need before closing them.
