Apps similar to FreeCircuitSim include Autodesk Tinkercad, which is free for personal use. Other options are Circuit JS, QUCS, SimulIDE and LTspice. There's no shortage of Circuit Simulators like FreeCircuitSim, with more than 50 alternatives for Windows, Linux, Mac, the web and Android.

Circuit Solver uses a simple drag and drop approach to building circuits. Simply drag the elements from the tool box onto the screen where you can wire and edit their values. Afterwards, hit the play button to simulate the circuit.




This App is designed to be an introduction to constructing and operating electronic circuits. Intuitive controls and layout make Circuit Builder the perfect App for understanding the basics of electrical and electronic circuits.




For engineers who want to expand the possibilities of power electronics. PSIM is the fastest and most reliable simulation tool. Built by engineers, for engineers.


TkGate is a event driven digital circuit simulator with a tcl/tk-based graphical editor. TkGate supports a wide range of primitive circuit elements as well as user-defined modules for hierarchical design.




Circuit Wizard is a revolutionary new system that combines circuit design, PCB design, simulation and CAD/CAM in one complete package.

Block model simulator for python BMS is a block model time simulator: it computes time values of time functions (called variables) linked by blocks which represent equations and behaviors between them.

Emulino is an emulator for the Arduino platform by Greg Hewgill, originally found on emulino: arduino cpu emulator.
StochSD (Stochastic System Dynamics) is a System Dynamics simulation software with focus on stochastics. It is a form of Continuous System Simulation (CSS) that in addition to model and simulate continuous flows between compartments, can handle transitions of discrete entities.
