Hide complexity until it matters.

Features

Diagramming tool that
scales with your architecture.

A canvas built for busy engineers.

Hierarchical Nesting

Systems within systems. Drill into any node to reveal its inner architecture. Model microservice clusters, bounded contexts, and deployment zones with unlimited depth.

FreeDraw Mode

Sketch freely. Annotate instantly. Collaborate live.

Switch to FreeDraw mode and draw directly on your diagrams - brainstorm, jot quick notes, circle pain points. Perfect for presentations, workshops, and remote calls.

Built for ease of use

Label connections with protocols, data flows, or descriptions. Edges auto-route around nodes and snap cleanly to ports.

Built for Dark Mode

Neumorphic clay design system. High-contrast, eye-friendly interface crafted for long engineering sessions.

Git Source Linking

Connect nodes directly to your repositories. A highlighted yet unobtrusive way to take quick peeks into the code running behind your architecture.

Context on demand

Zoom in to get exactly the technical detail you need, exactly when you need it. Get both big-picture clarity and deep precision in one tool.

Workflow

From blank canvas to
living architecture

Three steps to a diagram your whole team can understand.

🏗️

Create a diagram

Name your system and open the canvas. Diagrams are organized as workspaces you can share, clone, or evolve over time as your architecture grows.

🔗

Add & connect nodes

Drop in services, databases, people, and queues. Connect them with directed edges and label each relationship with the protocol or data flow it represents.

🔍

Drill in & explore

Click into any node to expand its internal architecture. Zoom, pan, and navigate the minimap. Share the diagram URL with your team for live review.
