Mokxi and EveryCircuit, compared fairly
EveryCircuit is a circuit simulator for the web, Android and iOS, known for animating voltage, current and charge as a circuit runs, with a large public gallery of circuits. Mokxi is a free circuit and firmware simulator in a browser tab. Here is where each one is the right answer.
Last checked September 2026
- 228parts on the bench
- 31boards running now
- 1.00xreal time, on every board

Where EveryCircuit leads
These are the strongest reasons to choose EveryCircuit today.
- Animated voltages, currents and charge that respond while you adjust a running circuit, which builds intuition fast.
- Apps for Android and iOS as well as the web, and the iOS app works without a connection.
- Analog and digital parts in one circuit, from transistors and op-amps to logic gates, flip-flops, a 555 and ADC and DAC converters.
- A public gallery that counts millions of circuits made by its users, and a class license for courses.
Where Mokxi leads
These are working parts of Mokxi you can open and test for yourself.
- The free plan is the whole simulator, with no limit on how many parts a circuit has.
- Microcontrollers on the same canvas: 31 boards running C++ compiled in the tab.
- SPICE decks run in the editor, on an engine checked against ngspice, and a breadboard at real 0.1 inch pitch with bench instruments wired in as parts.
- Classes with rosters, starter projects, checks that run on each submission, feedback and a gradebook.

Last checked September 2026. If anything here has gone stale, that is our mistake and we want to know.
| Mokxi | EveryCircuit | |
|---|---|---|
| Aimed at | Breadboard circuits, instruments and firmware | Understanding circuits through animation |
| Runs on | A browser, on computers, Chromebooks, tablets and phones | The web, Android and iOS |
| Price | Free with no size limit; paid plans for classes and more room | Free to explore; your own circuits past five components need a paid upgrade |
| Offline | Keeps running once the tab is open | The iOS app runs offline |
| Class tools | Rosters, starters, checks, submissions and a gradebook | A class license for educators |
