Welcome to WBO!
WBO is a free and open-source online collaborative whiteboard that allows many users to draw simultaneously on a large virtual board. The board is updated in real time for all connected users, and its state is always persisted. It can be used for many different purposes, including art, entertainment, design and teaching.
To collaborate on a drawing in real time with someone, just send them its URL.
The anonymous board is accessible to everyone. It is a happily disorganized mess where you can meet with strangers and draw together. Everything there is ephemeral. Go to the anonymous board
You can also create a private board, that will be accessible only to those who know its name:
