Features Everything you need to learn, build & simulate
A complete electrical circuit toolkit — all running locally in your browser, no server, no cloud, no account needed.
🔌
Drag & Drop Components
Place MCB breakers, switches, light bulbs, fans, motors and sockets from the palette. Components snap to a grid for clean, professional layouts.
⚡
Real-Time Simulation
Hit Run and watch electricity flow instantly. Energised wires animate, bulbs light up, fans spin. Toggle switches and see changes propagate live.
🔴
Fault Detection
The simulation engine detects open circuits, short circuits and overloads automatically. Faulty wires highlight in red for instant diagnosis.
🔀
Smart Wire Routing
Click a port to start wiring — ElectraSim auto-routes orthogonal wires around components. Custom multi-step wiring also supported.
📐
Multi-Select & Align
Shift-click or drag-select multiple components. Align left, center, right, top or bottom with one click for professional diagrams.
💾
Import, Export & Share
Save your circuit as JSON, export as SVG or PNG, or generate a shareable URL. Your work is autosaved locally and survives page reloads.
