Comparison

# Mokxi and Fritzing, compared fairly

Fritzing is a free, open-source tool for drawing and documenting a breadboard, schematic and PCB layout; it does not run your code or simulate a circuit's behavior. Mokxi is a live firmware and breadboard simulator. The two solve different halves of the same project, and this page says so plainly.

## Where Fritzing leads

These are the strongest reasons to choose Fritzing today.

- Free and open source, with an active community library of parts.
- Breadboard, schematic and PCB views of the same design, kept in sync, which is genuinely useful for documenting a build.
- A direct path from a design to an ordered, fabricated PCB through Fritzing Fab.
- Widely used for sharing and publishing wiring diagrams, which is a real and common need Mokxi does not aim to serve.

## Where Mokxi leads

These are working parts of Mokxi you can open and test for yourself.

- The circuit actually runs: your C++ is built by a real clang and executes against a cycle-accurate Arduino Uno or ESP32-C3, which Fritzing does not attempt at all.
- A breadboard on a real 0.1 inch grid that responds to a running circuit rather than a static drawing of one.
- No PCB design or fabrication path, and no offline desktop app: Mokxi is browser-only.
- Free with no account needed, versus Fritzing's free desktop app plus its separate, paid PCB fabrication service.

## Which one should you use

Straight answers. Where the other one is the right call, we say so.

### You want to watch your code and circuit actually run

Mokxi. Fritzing does not simulate a circuit's behavior.

### You need a wiring diagram to publish or hand to someone else

Fritzing is built for exactly that.

### You want to send a design off to be fabricated as a PCB

Fritzing, not Mokxi.

### You want to test a sketch before the parts arrive

Mokxi.
