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.
KiCad is an open source software suite for electronic design automation (EDA) - designing schematics of electronic circuits and printed circuit boards (PCB). KiCad is developed by Jean-Pierre Charras. And features an integrated environment between schematic capture, bill of...
EDA software that enables PCB designers to connect schematics, position components, route PCBs, and access extensive libraries, with features like SPICE simulation, drag-and-drop functionality, alignment tools, 3D models for enclosure fit, and direct links to manufacturers for parts replacement.
Digital graph paper for diagrams, technical sketches and geometric art.
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.
