Open-source initiative aiding designers, artists, and researchers in transforming prototypes to actual products, documenting circuits, sharing, teaching, and PCB manufacturing.


The best Circuit Simulator alternative to KiCad is Fritzing. It's not free, so if you're looking for a free alternative, you could try Velxio or LibrePCB. If that doesn't suit you, our users have ranked more than 50 alternatives to KiCad and 19 are Circuit Simulators so hopefully you can find a suitable replacement. Other interesting Circuit Simulator alternatives to KiCad are Proteus PCB design, EasyEDA, PADS PCB Design and eSim.

LibrePCB is a free EDA software to develop printed circuit boards. It’s currently under heavy development to bring out first stable releases as soon as possible.




Proteus PCB design combines the schematic capture and ARES PCB layout programs to provide a powerful, integrated and easy to use suite of tools for professional PCB Design.



Schematic capture, Ngspice based simulation, PCB layout, custom PCB manufacturing, for electronic engineers, educators, students and hobbyists.




The industry-leading, high-productivity, PCB-centric design solution for independent engineers.



eSim (previously known as Oscad / FreeEDA) is an open source EDA tool for circuit design, simulation, analysis and PCB design.




NI Circuit Design Suite software improves the PCB design process by integrating capture, simulation, and layout into a single toolchain with NI Multisim and Ultiboard software.


TINA Design Suite is a powerful circuit simulation package for analyzing, designing, and real time testing of analog, digital, VHDL, MCU, SMPS, RF, communication, optoelectronic and mixed electronic circuits and their PCB layouts.




The gEDA project has produced and continues working on a full GPL'd suite and toolkit of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production.




tscircuit is a framework for designing real electronics with Typescript and React. Your tscircuit code compiles into real-time previews for PCBs, schematics, 3D models and can be exported to fabrication files for manufacturing.


Sketch, simulate, and share your circuits, entirely in your browser -- no install required. Easy schematic capture and powerful SPICE-like, mixed-mode circuit simulation helps EE students, electronics hobbyists, and electrical engineers design faster.
