Diagraw, the free online collaborative whiteboard and diagram editor
Draw, collaborate, share and teach on a free infinite canvas. Diagraw is a collaborative online whiteboard and diagram editor with real-time collaboration, comments and version history.
Diagraw is a free online whiteboard to draw diagrams, whiteboards and software architecture maps on an infinite canvas. Collaborate in real time with cursors, presence and comments. Export to PNG, SVG or PDF, generate Mermaid code, save versions and share with a link.
What you can do on the canvas
- Draw diagrams with a hand-drawn stroke: boxes, arrows that stay attached to the shapes, free text and images.
- Architecture diagrams with 726 official AWS, Google Cloud and IBM icons (5 per cloud on the free plan).
- Import and export Mermaid, docker-compose and Miro boards, and export to PNG, JPG or PDF.
- Draft a first diagram from a plain-text description with Lyra, the built-in AI assistant.
How collaboration works
- Share a link and whoever opens it joins the live session with a name: no account and nothing to install.
- Live cursors, presence and comments with @mentions next to the drawing, so review does not move to chat.
- Version history on saved diagrams, so you can return to any earlier state.
- A session holds up to 100 participants at once, and only its creator can pause or resume it.
Free and Pro
- The canvas, sharing, collaboration and comments are free, with limits on saved diagrams, AI quota and share lifetime.
- Pro is 6 € per month or 60 € per year: unlimited AI, unlimited diagrams, extended history, permanent links and unbranded embeds.
