Unleash the Power of
Ourlu's Core
A unified Rust architecture powering AI patching, native multiplatform rendering, and seamless MCP integration.
Built for engineers.
Designed for everyone.
Every diagram type you need, powered by a Rust engine that outperforms everything else on the market.
Rust WASM Engine
Dagre layout ported to Rust, compiled to WASM. Sub-10ms layout computation — 20x faster than JavaScript.
Interactive Canvas
Drag nodes, edges re-route in real-time using A* pathfinding. Select, multi-select, lasso, align, distribute.
Mermaid → Interactive
Paste any Mermaid syntax. Flowcharts, Gantt, Sequence, Mindmap — all become editable interactive diagrams.
Flow Animations
10 animation styles — electric pulse, swarm flock, neon wave. Visualize data flow through your architecture.
Data Charts
Metrics, observability, specialized charts. Line, Bar, Heatmap, Flame Graph, Topology, Sankey and more.
Vectorial PDF Export
Export your documents with charts rendered as inline SVG in PDF. Crisp at any zoom level, print-ready.
49 chart types. One engine.
From flowcharts to flame graphs. Every chart type an engineering team needs, rendered by the same Rust WASM core.
