livediagram: diagram together, no sign-in required
livediagram is a collaborative diagram and mindmap editor that lives in the browser. It is built around one stubborn principle: the canvas always works without signing in. A visitor can open a link and build a real diagram before being asked to create an account. There is no sign-in wall in front of the editor, ever, because the easiest way to get a team drawing together is to remove every step between them and the canvas.
Real-time multiplayer, built in
Collaboration is the product, not a feature. Everyone on a diagram sees live cursors, selection rings, and comment threads as they happen, plus a laser pointer for walking a group through a design in a call. Each diagram runs in its own realtime room, so presence and edits stay responsive even with a crowd on the canvas.
A canvas that holds up to real work
Build with ten core shapes, sticky notes, text, and images. Connect them with arrows you can draw straight, curved, or angled, each with draggable curve and elbow handles, configurable thickness and arrowhead size, and optional labels. The Pencil tool handles freehand sketching, with an optional shape-recognition mode that converts rough scribbles into clean rectangles, circles, diamonds, and lines. Marquee select, shift-click, groups, and a format painter keep big diagrams under control. Lock elements you don't want to move, and link any element to another tab or an external URL.
Start fast, stay organized
Open one of 17 templates (mind map, flowchart, Kanban, SWOT, retrospective, org chart, timeline, fishbone, user journey, UI wireframes, and more) or start blank. Recolor an entire diagram, every shape and arrow, with one of 18 themes in a single click. Group related work into tabs within a diagram, link across them, copy a tab into another diagram, and file everything into nested folders.
Nothing gets lost
Every change is recorded in a per-tab activity log, and you can revert any single entry with one click, even after later edits landed on top of it. Share view-only or editable links per diagram and revoke them whenever you want. Anyone you share with can make their own copy. Export any tab to Markdown, PDF, PNG, or JSON, and import the JSON back as a new tab.
Free, open, and yours

You can self-host the entire stack on your own Cloudflare account; the open-source core never calls home and never gates features behind a license check.
