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




Fritzing is described as 'Open-source tool supporting designers in prototyping, documenting circuits, sharing, and creating PCB layouts, empowering artists, researchers, and hobbyists' and is a very popular circuit simulator in the education & reference category. There are more than 50 alternatives to Fritzing for a variety of platforms, including Windows, Mac, Linux, Web-based and Flathub apps. The best Fritzing alternative is KiCad, which is both free and Open Source. Other great apps like Fritzing are Autodesk EAGLE, Square Sketch, LibrePCB and Proteus PCB design.
