Source: https://mokxi.com/vs/kicad Updated: 2026-11-02 Comparison # Mokxi and KiCad, compared fairly KiCad has no official online version; it is a desktop suite. Mokxi runs in a browser and covers a smaller part of the job: it simulates the circuit and its firmware, draws the schematic, lays out a simple two-layer through-hole board and exports a KiCad schematic for anything bigger. KiCad is a free, open-source suite for schematic capture and PCB layout, used for professional boards as well as hobby ones. Mokxi is a browser simulator that runs the microcontroller and the circuit together, with a schematic and a basic PCB view on top. They meet in the middle, and a Mokxi circuit can be handed on to KiCad as a schematic file.

KiCad simulates circuits, not firmware. - Nothing to install: it runs in a browser tab, including on a school Chromebook. - A KiCad 8 schematic and netlist export on Pro, built from the nets the simulator ran, so a working breadboard becomes a starting point in KiCad. - Its own PCB view is deliberately small: two layers, through-hole parts, an Uno shield outline, autoroute, a check against a cheap fab’s rules, and Gerber files with ordering on Pro. No surface mount parts and no 3D view. ## Side by side Last checked November 2026. If anything here has gone stale, that is our mistake and we want to know. | Mokxi | KiCad Aimed at | Running firmware and a circuit together, then building it | Designing schematics and PCBs, from hobby to professional Runs in | A browser tab | A Windows, macOS or Linux install Simulates | Firmware on the chip, digital logic and analog circuits, live | Analog circuits with SPICE models through ngspice PCB layout | Two layers, through-hole only, Gerber export on Pro | Up to 32 copper layers, surface mount and through-hole Moving between them | Exports a KiCad schematic and netlist (Pro) | Reads the exported schematic in KiCad 8 and later Price | Free; Pro for exports, private projects and more room | Free and open source Sources for KiCad - KiCad: about (license, platforms, Gerber and IPC-2581 output) - KiCad 9 PCB Editor manual (32 copper layers, 3D viewer, Update PCB from Schematic) - KiCad: PCB design (shove router, scripted DRC) - KiCad: SPICE simulation with ngspice ## Which one should you use Straight answers. Where the other one is the right call, we say so. ### You are laying out a board with surface mount parts or more than two layers KiCad. ### You want to test the sketch and the circuit before ordering anything Mokxi, then export the schematic to KiCad if the board outgrows Mokxi’s PCB view. ### You are on a Chromebook or a computer you cannot install software on Mokxi runs in the browser. ### You need a 3D model of the finished board for an enclosure KiCad. ## Looking for KiCad online? There is no official web version of KiCad, so a search for one usually means one of two things: you are on a machine where you cannot install software, or you want to try a circuit before committing to a layout. Mokxi helps with both, inside its limits. Build and run the circuit in the browser, look at its schematic, and lay out a simple through-hole board there. When the board needs what Mokxi does not do, export the schematic as a KiCad file from the Schematic view, open it in KiCad on a computer that has it, assign footprints and update the PCB from it. The guide below has the steps and the errors people hit on the way. How to export a circuit to KiCad ## Compare the other options The same straight comparison for the tools teachers, students and makers also consider.

Not an official one. KiCad is a desktop suite for Windows, macOS and Linux. Mokxi runs in a browser and can export a schematic that KiCad 8 and later open. Can Mokxi replace KiCad for PCB design? For a small two-layer through-hole board or an Uno shield, it can take you to Gerber files. For surface mount parts, more layers, a 3D view or a professional layout, use KiCad. Should I use Mokxi if you are laying out a board with surface mount parts or more than two layers? KiCad. Should I use Mokxi if you want to test the sketch and the circuit before ordering anything? Mokxi, then export the schematic to KiCad if the board outgrows Mokxi’s PCB view. Should I use Mokxi if you are on a chromebook or a computer you cannot install software on? Mokxi runs in the browser. Should I use Mokxi if you need a 3d model of the finished board for an enclosure? KiCad. ## Try it yourself A comparison page is somebody else’s opinion.
