Advanced Circuit Maker

Advanced Circuit Maker is a fully offline HTML schematic editor for quickly drawing circuits in your browser without installing any software. It includes a snap-to-grid workspace, component library (R, C, L, diode, LED, voltage source, and ground), wire routing, pan/zoom, multi-select, rotate, and undo/redo. An inspector panel lets you edit reference designators, values, and rotation. You can export your work as SVG, PNG, JSON, and a basic SPICE-style netlist, with autosave and an accidental-close warning for data protection. Powered for private use with zero uploads and optimized for Chromium browsers.
