Source: https://mokxi.com/vs/circuitverse Updated: 2026-10-04 Comparison # Mokxi and CircuitVerse, compared fairly Mokxi is a free alternative to CircuitVerse for classes that go past logic: the same gates and flip-flops in a browser, plus analog circuits, bench instruments and microcontrollers on 31 boards, with a path from one NAND gate to a working computer. CircuitVerse is a free, open-source digital logic simulator that runs in the browser, with groups and assignments for teachers and a large community of shared circuits. Mokxi is a free circuit and firmware simulator in the browser with its own logic path and class tools. The two overlap more than most pairs on this site, so here is where each one is the right answer. Last checked September 2026 Start building free or see the plans - 228 parts on the bench - 31 boards running now - 1.00x real time, on every board Click to open it in the editor Running here on our own RISC-V core, on the machine in front of you. The Mokxi editor running a four-bit binary counter: two 74HC74 flip-flop chips on a breadboard counting a clock up a row of LEDs. ## Where CircuitVerse leads These are the strongest reasons to choose CircuitVerse today. - Free and open source, in the browser, with nothing to install. - Built for digital logic: subcircuits, multi-bit buses, timing diagrams, testbenches, and circuits generated from a truth table. - Teacher groups and assignments with deadlines and grading in a built-in preview, and assignments that connect to an LMS such as Canvas or Moodle through LTI. - A large community: its site counts more than 1.3 million circuits and 314,000 users, and circuits embed in a web page or Google Slides. ## Where Mokxi leads These are working parts of Mokxi you can open and test for yourself. - Beyond logic: analog parts solved with real device models, SPICE decks run from the editor, and bench instruments wired in as parts. - Microcontrollers on the same canvas: 31 boards, with C++ compiled in the tab. - A breadboard at 0.1 inch pitch with real 74HC chips and a 555, beside the ideal gates. - A path from one NAND gate to a computer: custom chips checked against truth tables, the Kestrel CPU, a program ROM with an assembler and a terminal. ## Side by side Last checked September 2026. If anything here has gone stale, that is our mistake and we want to know. | Mokxi | CircuitVerse Aimed at | Logic, analog circuits and firmware | Digital logic Runs in | A browser tab | A browser tab Price | Free; paid plans for classes and more room | Free and open source Class tools | Rosters, starters, checks that run on each submission, feedback and a gradebook CSV | Groups, assignments with deadlines, grading, and LMS links through LTI Open source | No | Yes Sources for CircuitVerse - CircuitVerse: home page (features, community numbers) - CircuitVerse: for teachers - CircuitVerse docs (circuit elements, groups, Google Slides) - CircuitVerse blog: LMS integration through LTI ## Which one should you use Straight answers. Where the other one is the right call, we say so. ### You teach digital logic only and want a simple, free browser tool CircuitVerse is a strong choice. ### Your school runs assignments through Canvas or Moodle CircuitVerse connects to an LMS through LTI. Mokxi exports a gradebook CSV instead. ### You want open source CircuitVerse. Mokxi is not open source. ### You want logic, analog circuits and a microcontroller in one course Mokxi. ### You want students to build up to a working CPU, one checked chip at a time Mokxi has that path built in. ## Compare the other options The same straight comparison for the tools teachers, students and makers also consider. Mokxi vs Tinkercad Circuits Mokxi vs Wokwi Mokxi vs Proteus Mokxi vs Fritzing Mokxi vs SimulIDE Mokxi vs Falstad (CircuitJS) Mokxi vs Multisim Mokxi vs LTspice Mokxi vs Logisim-evolution Mokxi vs Digital Mokxi vs Qucs-S Mokxi vs EveryCircuit Compare every simulator ## In short Should I use Mokxi if you teach digital logic only and want a simple, free browser tool? CircuitVerse is a strong choice. Should I use Mokxi if your school runs assignments through canvas or moodle? CircuitVerse connects to an LMS through LTI. Mokxi exports a gradebook CSV instead. Should I use Mokxi if you want open source? CircuitVerse. Mokxi is not open source. Should I use Mokxi if you want logic, analog circuits and a microcontroller in one course? Mokxi. Should I use Mokxi if you want students to build up to a working cpu, one checked chip at a time? Mokxi has that path built in. ## Try it yourself A comparison page is somebody else’s opinion.
