A high-performance, browser-native vector design environment specifically optimized for Electrical Schematics, Software Architecture, and Architectural Floorplans.
Most web-based drawing tools are either generic (Figma/Canva) or overly complex legacy CAD ports. Schema Editor bridges the gap: it provides the precision and domain-specific logic of engineering software with the speed and accessibility of a modern web app.
- 🔌 Intelligent Manhattan Routing: Automatic orthogonal wiring that stays clean as you move components.
- 🔍 Real-Time Wire Tracing: Instantly highlight the complete connectivity path of any signal or net.
- 🏗 Domain-Specific Kits: Pre-built, high-quality symbol libraries for Electrical (PCB/Circuit), Software (UML/ERD/FSM), and Construction (AEC/Floorplans).
- 🚀 Zero Dependencies: Built entirely with Vanilla JS and SVG. No heavy frameworks, no virtual DOM overhead—just pure performance.
- 🎮 3D View Transformation: Native Tilt, Yaw, and Perspective controls for interactive diagram presentations.
- Touch-Optimized Canvas: Smooth pan/zoom with multi-touch and stylus support.
- Precision Snapping: Intelligent grid and object snapping for pixel-perfect engineering.
- Layer Management: Full control over visibility, locking, and stacking order.
- Measurement System: Calibrated system supporting both Metric and Imperial units.
- Multi-Format Export: Save as SVG, PDF, HPGL, JSON, or export netlists directly to TAFNE.
Focus on connectivity. Specialized symbols for passive components, ICs, and connectors. Built-in logic for Netlist generation and BOM export.
Build UML diagrams, ERDs, and State Machines. Features auto-routing for sequence diagrams and Mermaid-compatible export.
Precision tools for architectural layouts. Includes symbols for walls, openings, MEP (Mechanical/Electrical/Plumbing), and site utilities.
