Diagram together, live.

Make whatever’s on your mind, from diagrams and whiteboards to illustrations and documents. Share a link and your team builds it with you in real time.

Every way to work, on one canvas: pick one to see it in action

No catch

Built with your values in mind

livediagram is free, open and private for everyone, and it stays that way.

livediagramFor everyone

Start in seconds, go as deep as you like

Open a link and draw. When the idea grows, the same canvas takes images, tables, icons, mind maps and freehand sketches, and guides and snapping keep it neat while you work.

See how simple it is

Built for working together

Share a link and your team is on the canvas with you: live cursors, comments on any element, actions assigned to teammates, and a big system split across tabs that link to each other.

Explore collaboration

Present straight from the canvas

Turn what you drew into slides or a page-perfect infographic, point with a laser, spotlight the one piece you mean, and let arrows show the flow. No export, no second tool.

Make it yours, keep it tidy

Start from a template, recolour with a theme or build your own, then keep a busy canvas in order with layers, locking and a format painter.

Explore customisation

Open, private, and connected

MIT-licensed and self-hostable. Your work saves itself and steps back with one keystroke, a document can live only in your browser, and your AI tools can read and build diagrams for you.

Privacy by design

Your data, your call

We don’t make money by being creepy. No third-party trackers, no ads, no resale, no surprise audience. Just a diagram editor that treats your work like your work.

No third-party analytics

No Google Analytics. No Segment. No marketing pixels. The only product telemetry is anonymous, first-party events served from our own API, with every event we measure listed publicly on /telemetry.

Your data is yours

Every document lives in your own row, scoped to your owner id. Export any tab to PNG, SVG, PDF, Mermaid, Markdown, or portable JSON whenever you like, and delete your account from settings to remove it all in one go. We don't make money by holding it hostage.

Never sold, never traded

We don't sell your data. We don't trade it. We don't share it with advertisers or model trainers or anyone else. There is no paid tier and no plan to add one, so we have no commercial pressure to monetise what you draw.

Encrypted at rest and in transit

All persistence runs on Cloudflare D1 + R2, which encrypt every row and blob at rest with AES-256. Every request is TLS, end to end. The same protections protect telemetry, share links, and uploaded images.

Private by default

A new document is visible only to you until you generate a share link. Share links are unguessable codes you choose to hand out: protect them with a password, set them to expire automatically after a week, a month, or six months, or revoke them at any time, instantly disconnecting anyone currently using one.

Open source, auditable

The whole stack (editor, API, this site) is on GitHub under the MIT license. Anything we claim here, you can read in the source. Run your own copy if you prefer, on your own Cloudflare account, in an afternoon.
