CircuitSim
CircuitSim is a full SPICE circuit simulator with a 3,000+ component library and a modern schematic editor. No install, free to get started. Built for students, educators, and professionals.
It runs in a browser tab and needs no admin rights, so it works on Chromebooks and locked-down school laptops. Run seven kinds of analysis: interactive, interactive operating point, transient, AC sweep, DC operating point, DC sweep, and parameter sweep. Results plot on oscilloscope-style charts, with probes you can drop anywhere in the circuit. Define custom parts from SPICE model text or import KiCad symbols.
CircuitSim also imports Multisim Live designs ahead of that product's retirement on September 15, 2026. It is the only browser tool that opens .csim, .ms14, and .msjs files, and it rebuilds the schematic with wiring, placement, net labels, probes, and simulation settings intact.
Classroom licensing adds seat assignment, anonymous student seats, and private student work.
