You've got Mermaid everywhere, in your repos, your docs, your AI agents, but nowhere to centralize it all. Ourlu brings all your diagrams together, makes them interactive, and keeps full history and versioning. Drag a node, links follow in real time. Export to PDF, share a link. Works on web, desktop, and mobile, same Rust engine everywhere.
Everything you need to document, track, and share your projects visually, powered by a Rust engine with no equivalent on the market.
Dagre ported to Rust, compiled to WASM. Sub-10ms layout, 20x faster than JavaScript. You feel the difference from the very first diagram.
Drag your nodes, links recalculate live using A* routing. The chart respects your layout while staying perfectly readable.
Paste any Mermaid or ASCII code. Flowcharts, Gantt, Sequence, Mindmap, everything becomes a diagram you can touch and edit.
10 animation styles: electric pulse, swarm flock, neon wave. Bring your architectures to life and make your presentations memorable.
Metrics, observability, specialized charts. Line, Bar, Heatmap, Flame Graph, Topology, Sankey, all in one place.
Export as vectorial PDF, crisp at any zoom level, or share a live link. No more blurry screenshots in your presentations.
Drop in a Markdown doc with Mermaid blocks, upload your .mmd files, or write directly in the editor. We handle the rest.
Every code block becomes a real interactive diagram. Drag nodes, links follow intelligently. It's smooth, it's beautiful.
Edit directly in the chart, add animations, then export as vectorial PDF or send a live link to your team.
One Rust core compiled to WASM & FFI. Same engine on web, desktop (Tauri), and mobile. Your work follows you everywhere.
From flowcharts to flame graphs, including Gantt and Kanban. Everything a team needs to document and manage their projects, rendered by the same Rust WASM core.
