Does Mermaid Flow Studio work offline?

Yes. After the first load, Mermaid Flow Studio caches the app shell and runtime assets so editing, rendering, and exporting continue to work offline.

Which export formats are supported?

You can export rendered flow diagrams as SVG, PNG, JPEG, and PDF directly in the browser.

Is Mermaid source kept private?

Yes. Core editing, rendering, and exporting are all performed client-side without a backend dependency.

No sign-in, no backend

Core editing, rendering, and export flow stay on-device for a straightforward private workflow.

Offline after first visit

PWA-style caching keeps the studio usable without a constant network connection.

FAQ

Common questions about Mermaid Flow Studio

What Mermaid syntax is supported?

The studio is tuned for Mermaid flowchart syntax first, including common `flowchart`, `graph`, decision, and directional layouts.

How does offline mode work?

A service worker caches the app shell and runtime assets after the first successful load. Once cached, editing, preview, and export continue to work offline.

Are exports generated on a server?

No. SVG generation, rasterization, and PDF creation all happen client-side in the browser.

Can I share a diagram draft?

Yes. The share action copies a URL with encoded local state so another browser can open the same Mermaid source and styling configuration.
