KiCad is described as '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' and is a very popular circuit simulator in the education & reference category. There are more than 50 alternatives to KiCad for a variety of platforms, including Windows, Mac, Linux, Web-based and Flathub apps. The best KiCad alternative is Fritzing. It's not free, so if you're looking for a free alternative, you could try LibrePCB or EasyEDA. Other great apps like KiCad are Autodesk EAGLE, Altium Designer, Proteus PCB design and Square Sketch.
