Circuit JS VS LTspice
Is Circuit JS a good alternative to LTspice?Comments about Circuit JS as an Alternative to LTspice
guoiewbvc923The best free tool to simulate circuits in the browser. There are almost no other tools to do simulations in a browser and it even allows to save and load circuits as files.
0It isn't a SPICE software!
1CircuitJS does not run Spice (the core circuit simulator used by LTSpice, PSpice, and others). CircuitJS does not have built-in models for manufactured components nor does it allow you to define your own subcircuits. It was never built for commercial circuit design (while LTSpice was).
