As answered by people managing CircuitSim and Zcode.
CircuitSim's answer
CircuitSim earns the choice when the constraint is the browser: students on Chromebooks, online courses, schools where IT will not install desktop software. Within that space, CircuitSim pairs true SPICE simulation with classroom licensing, private student seats that need no login, and an importer for Digilent's Multisim Live files.
CircuitSim's answer
CircuitSim runs a real SPICE engine entirely in the browser. Simulation results match what desktop SPICE tools produce, with nothing to install. On top of the simulator there is a large searchable component catalog and classroom groups with private student seats: a teacher shares a join link and students work without creating accounts, which keeps classes clear of the student-privacy problems that come with provisioning accounts. CircuitSim also imports designs from Digilent's Multisim Live, which matters right now because Digilent is retiring Multisim Live in September 2026.
CircuitSim's answer
Educators and students, mostly. The core user teaches circuits somewhere that desktop software is not an option: community college electronics programs, university ECE labs, online courses, and K-12 engineering classes where students are on Chromebooks. Outside the classroom, hobbyists and working engineers use CircuitSim for quick analog and digital simulation without installing anything. A large share of new users right now are instructors moving their courses over from Digilent's Multisim Live before it retires in September 2026.
