Everything in this category
MIT licensed
The whole thing (editor, API, marketing site) is on GitHub under the MIT license. Fork it, rebrand it, ship your own variant.
No servers to babysit
Static-export frontend deploys to Cloudflare Workers; the API is a Worker with D1 + Durable Objects. No VMs, no containers, no nightly restarts.
No tracking pixels
No third-party analytics, no ad pixels, no SDK calls home. The only usage data is anonymous, first-party product events, and they are public: see exactly what we measure on the telemetry page.
Work fully offline
Flip on Offline Mode when you create a diagram and it is saved only in your browser: no account, no server, no sync. Yours alone. Move it to the cloud (or pull one back down) whenever you like.
