Build real circuits with components. Powered by nodal analysis physics. No download. No account required to start.
Professional-grade tools wrapped in an intuitive, game-like 3D interface.
Orbit, zoom, and drag components on a real 3D workbench. Every component is a detailed 3D model — not a flat schematic symbol.
Modified Nodal Analysis (MNA) solver — the same method used by SPICE. Parallel paths, voltage dividers, and multi-source circuits all solved correctly.
From basics like resistors and LEDs to transistors, logic gates, relays, and RGB LEDs. Every component has accurate DC simulation behavior.
Ask CircuitForge AI why your LED isn't lighting up. Powered by Gemini — responses stream back fast and smart.
Sign in with Google to save unlimited circuits. Share any circuit with a public link — one click, anyone can load and explore it.
Load a working circuit instantly: LED + resistor, voltage divider, H-bridge, transistor switch, logic gates, and more.
Click the sidebar, place it on the 3D board.
Connect pins with the wire tool.
MNA solver shows live voltage and current on every component.
Build circuits for physics class without buying components. Understand Ohm's Law and Kirchhoff's laws visually.
Prototype your Arduino or ESP32 circuit before soldering. Test LED arrays, motor drivers, and sensor circuits instantly.
Demonstrate circuit behavior to students in 3D. Share live circuit links in course materials.
