There are plenty of ways to draw a diagram. livediagram is built around four ideas that make it a comfortable home for teams: it is free, it is open source, it never puts a sign-in wall in front of the canvas, and it is multiplayer from the start. Here is what each of those actually means for you.
Free, with no paid tier
livediagram is free for everyone. There is no paid tier, no "Pro" upgrade, no trial that expires, and no plan to introduce any of those. Every feature in the product is available to every user. livediagram.app costs nothing to use.
Open source
The whole codebase is MIT-licensed and publicly viewable. That has real consequences:
- You can check the claims. How a canvas is stored and what telemetry records are in the open for anyone to audit.
- No lock-in. Because the code is open and your canvases export to portable formats, you are never trapped.
No sign-in wall
The canvas always works without signing in. A first-time visitor can open a new canvas, build something real, and only later be asked to create an account, never blocked by a modal before they have even started. An account adds cross-device sync and teams, but it is never a gate in front of the editor.
Multiplayer from the first shape
Collaboration is not a bolt-on. Hand someone a share link and they join the same canvas, where everyone sees live cursors, live selections, and every edit as it happens. To keep edits from colliding, an element another person currently has selected is gently locked for everyone else.
Real-time sharing
Hand over a link and collaborate live, even with guests.
The canvas
Shapes, arrows, and freehand on one fast surface.
Themes
Recolour a whole diagram to match your style.
Templates
Start from a ready-made layout instead of a blank page.
The best argument for livediagram is the canvas itself. Open a new diagram and try it, no account needed.
