Tidecharts is a live editor for mermaid.js diagrams which sets itself aside from others for being completely private - only runs in your browser, very fast and feature rich! Best of all is, it's free!
Super useful! I've been wanting a simple, fast way to work with Mermaid.js in the browser — Tidecharts nails it. No setup, no clutter, just write and see the diagram instantly. The UI is intuitive, and having everything side-by-side (code + diagram) just makes the workflow feel natural and productive. Love that it's private and free too.
Thanks @joao_verissimo2! Happy to hear!
