Excalidraw
Virtual whiteboard — hand-drawn diagrams, real-time collaboration.
MIT-licensed alternative to Miro with E2EE collaboration, component library, and export to PNG/SVG/JSON. React npm package for embedding.
Miro is a cloud-based collaborative whiteboard, priced per seat from $8/member/month on the Starter plan up to custom Enterprise pricing, with every workspace member counted toward the bill on paid plans. Teams that want an unlimited number of collaborators without per-seat costs, or that want to self-host their whiteboard data, look at open-source alternatives.
Excalidraw is the open-source option here — a hand-drawn-style virtual whiteboard with real-time collaboration that can be self-hosted with no per-user licensing.
