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.




iCircuit is described as 'The easy to use electronic circuit simulator and designer - the perfect tool for students, hobbyists, and engineers' and is a circuit simulator in the education & reference category. There are more than 25 alternatives to iCircuit for a variety of platforms, including Windows, Mac, Linux, Web-based and Flathub apps. The best iCircuit alternative is KiCad, which is both free and Open Source. Other great apps like iCircuit are Fritzing, Circuit JS, Square Sketch and QUCS.
