Why Use livediagram?

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. The hosted version at livediagram.app costs nothing to use, and it gets the same feature set as a self-hosted copy.

Open source and self-hostable

The whole codebase is MIT-licensed and publicly viewable. That has real consequences:

• Anyone can self-host. Run livediagram on your own infrastructure with the full feature set, no subscription and no license check phoning home.
• No lock-in. Because the code is open and your diagrams export to portable formats, you are never trapped.
• Optional dependencies stay optional. Accounts (and the services behind them) are optional; a self-hoster can run a pure-guest deployment where the editor is fully usable with no external services beyond hosting.

No sign-in wall

The canvas always works without signing in. A first-time visitor can open a new diagram, 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.
