What is Mermaid Studio?

Mermaid Studio is a local-first editor for Mermaid diagrams — write code or draw nodes, and see your diagram rendered live as you type.

Live preview — the rendered diagram updates as you type. Visual editor — arrange and connect 26 diagram shapes by drag & drop. Full Mermaid support — flowcharts, sequence, class, state, ER, gantt, git graph and more. Light & dark themes that follow your system. Folders and full-text search to organize your diagrams. Export to PNG, JPEG or SVG. Local-first: your diagrams never leave your device. No account, no cloud. English & French interface.

The free version includes the full editor with up to 5 diagrams. Premium unlocks unlimited diagrams, advanced exports and an ad-free experience by default.

Licensing: the web application (this listing) is 100% open source under the MIT license. A separate Android edition is distributed on Google Play; the Android app is not open source.
