Qucs-S Alternatives

Qucs-S is described as 'spin-off of the Qucs cross-platform circuit simulator. "S" letter indicates SPICE. The purpose of the Qucs-S subproject is to use free SPICE circuit simulation kernels with the Qucs GUI' and is an app. There are more than 25 alternatives to Qucs-S for a variety of platforms, including Windows, Mac, Linux, Online / Web-based and iPhone. The best alternative is Circuit JS, which is both free and Open Source. Other great apps like Qucs-S are QUCS, LTspice, EasyEDA and Solve Elec.

Qucs-S alternatives are mainly Circuit Simulators but may also be Electronic Design Automation Tools or CAD Software. Filter by these if you want a narrower list of alternatives or looking for a specific functionality of Qucs-S.
