Miro is the most widely used online whiteboard, with 100M+ users and over 250,000 companies, and it has a free plan with 3 editable boards. Lucidspark, from the Lucid suite that counts 100M+ users, is best for teams already in Lucidchart. Explain Everything leads in classrooms with 24M+ teachers and students, and Conceptboard, with 14M+ users, is the pick for keeping data in Germany. For a free sketch board, Excalidraw is open source.
How it's ranked: The number of users each vendor states on its own website, read November 14, 2026. Lucid's 100M+ covers its whole suite (Lucidchart and Lucidspark), so Miro, whose count is for Miro itself, ranks first on the tie. Klaxoon publishes a count of corporate clients (7,500+), not users, so it ranks below the user counts. FigJam, Mural, Excalidraw, Whimsical and Collaboard publish no user count and are ranked last, in editorial order.
