    The 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.

    It isn't a SPICE software!

    CircuitJS 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).
