About WBO
WBO is a minimal open-source whiteboard for drawing together in the browser. There is no account or sign-up: you either join the busy public board, create a private board with a random name that only people with the link can reach, or create a named board at a custom address. Everyone connected sees strokes appear in real time on a large canvas, and board contents are saved on the server so you can come back later. Tools are basic: pencil, lines, rectangles, ellipses, text, an eraser, a hand tool and zoom, with export to an image. Because the code is open source, schools, companies and hobbyists often run their own instance with Docker, which keeps drawings on their own servers. The hosted site is free and community-run. It has no templates, sticky notes, permissions or integrations, and anyone with a board link can edit it, so it suits quick sketches, tutoring and casual collaboration rather than structured work.
Best for: Teachers, tinkerers and teams wanting a free shared drawing board they can self-host.
