About Miro

Miro is a collaborative whiteboard for workshops, diagrams, and remote facilitation. Open alternatives prioritize real-time canvases you can self-host or embed in docs workflows.

Frequently asked questions about Miro alternatives

What open-source tools replace Miro?

Excalidraw, TLDraw-based tools, and self-hosted whiteboards cover many facilitation needs. Diagram-as-code (Mermaid) can replace static architecture boards.

Is Excalidraw enough for workshops?

For sketching and lightweight facilitation, yes. Large enterprise template libraries and complex permissions may still favor commercial suites.
