Welcome to the free online whiteboard 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 public board is accessible to everyone. It is a happily disorganized mess where you can meet with anonymous strangers and draw together. Everything there is ephemeral.Go to the public board
You can create a private board with a random name, that will be accessible only by its link. Use this if you want to share private information.Create a private board
