▊Every diagram type you need, powered by a Rust engine that outperforms everything else on the market.
Dagre layout ported to Rust, compiled to WASM. Sub-10ms layout computation — 20x faster than JavaScript.
Drag nodes, edges re-route in real-time using A* pathfinding. Select, multi-select, lasso, align, distribute.
Paste any Mermaid syntax. Flowcharts, Gantt, Sequence, Mindmap — all become editable interactive diagrams.
10 animation styles — electric pulse, swarm flock, neon wave. Visualize data flow through your architecture.
Metrics, observability, specialized charts. Line, Bar, Heatmap, Flame Graph, Topology, Sankey and more.
Export your documents with charts rendered as inline SVG in PDF. Crisp at any zoom level, print-ready.
Drop in any document with Mermaid code blocks. Or use our editor to write from scratch.
Every code block becomes an interactive diagram. Drag nodes, the edges follow with A* routing.
Modify styles, add animations, then export as vectorial PDF or share a live link.
One Rust core compiled to WASM & FFI. Same engine on web, desktop (Tauri), and mobile — zero re-implementation.
From flowcharts to flame graphs. Every chart type an engineering team needs, rendered by the same Rust WASM core.
