I built this because I found myself constantly needing to quickly visualize architecture or sequence flows, but I hated having to log into heavy enterprise tools (or deal with their paywalls) just to render a simple diagram.
FlowViz is a clean, minimal wrapper around Mermaid v11. My main goals were speed and privacy:
Zero backend: There is no database. The rendering happens entirely in your browser via WASM/JS. Your diagram data never leaves your machine.
Instant preview: It renders live as you type.
Clean export: You can instantly download the output as a scalable SVG.
It's completely free to use with no accounts required. I'd love to hear your feedback on the UI or any feature requests you might have!
