LabWired The easy way to build hardware

LabWired vs. Mokxi

A classroom simulator and a firmware-team simulator, compared from their own pages

Mokxi is a free browser simulator built around the breadboard and the classroom: it compiles in your tab, solves analog circuits, and wraps the simulator in a teacher workflow. LabWired is built for firmware teams and AI agents: Nordic DK and STM32 Nucleo boards, an AI that designs the circuit, a hosted MCP server, PCB and 3D views, and CI. Both run several boards in one simulation. Here is where each one is the better pick.

Where Mokxi leads

  • Analog circuits. Nodal analysis with real device models, DC sweeps, Bode plots and SPICE decks (Mokxi vs Wokwi). On circuits the MCU senses, LabWired co-simulates resistors, capacitors, inductors, diodes, BJTs and MOSFETs (the npn, pnp, nmos and pmos parts), and op-amps and comparators (opamp, LM358, LM393) in the core, next to the firmware, with its multimeter and function generator in the same circuit (labwired-core crates/core/src/analog; large-signal device models with no device capacitance, per device.rs).
  • Compiling in the browser. A real clang builds the sketch in your tab, with no build server or queue (Mokxi vs Wokwi).
  • The breadboard and the classroom. A 0.1-inch breadboard with rails, and a class workflow with starters, checks, submissions, feedback and a gradebook export (Mokxi vs Wokwi).
  • Maker and Linux boards. Its 35 boards include the ESP8266 NodeMCU, Wemos D1 mini and ESP-01S, and the Raspberry Pi 4, Pi 5 and Zero 2 W running Python with gpiozero and RPi.GPIO, all on the free plan (Mokxi: Pricing).
  • Price. Free with every board and part; Pro is $10 a month or $100 a year (Mokxi: Pricing).
  • A source debugger. Breakpoints in the gutter, Pause, stepping, registers and your own variables, with the whole circuit frozen while the board is halted (Mokxi: The debugger).
  • Bench instruments you wire in. A two-channel scope, a function generator, a multimeter, a bench supply and a four-channel logic analyzer with UART, I2C and SPI decoding (Mokxi vs Wokwi).
  • VS Code and git. A VS Code extension and a command-line tool keep the sketch in your own GitHub repository, with push, pull, run, compile and upload as VS Code tasks (Mokxi: VS Code and GitHub, Mokxi vs Wokwi). Since October 2026, Mokxi for VS Code is part of Pro (Mokxi: Pricing).
  • Coming from Wokwi. It imports Wokwi projects, exports a Wokwi zip, and its CI reads Wokwi scenario files (Mokxi vs Wokwi, Mokxi: Simulation tests in CI).

Where LabWired leads

  • Nordic DK and STM32 Nucleo boards. LabWired runs the nRF52840 DK, nRF5340 DK, nRF54L15, NUCLEO-F401RE, NUCLEO-H563ZI, NUCLEO-L476RG and more (Parts). Mokxi's board list names the STM32F411 Black Pill and STM32F103 Blue Pill for STM32 (Mokxi: Pricing). It does run a Nordic chip, the nRF52833 on the BBC micro:bit V2 (Mokxi: micro:bit); no Nordic DK boards are listed. See the nRF52840 simulator and the STM32 Nucleo simulator.
  • AI that designs the circuit. The Architect in the Playground builds the circuit from a description, writes the firmware and tests it. Mokxi's Ask answers questions about the circuit on the canvas, using an API key from your own AI provider (Mokxi: Ask).
  • A hosted MCP server. Agents connect to https://api.labwired.com/mcp over OAuth from Claude, Codex, Cursor, VS Code or ChatGPT (LabWired for agents). Mokxi's developer page documents a REST API, a CLI and a GitHub Action; it lists no MCP server (Mokxi: Developers).
  • PCB and 3D views, and KiCad export. The Board view shows copper, schematic and 3D. Agents can create, place, route and export a PCB, and export a KiCad netlist, schematic, BOM, .kicad_pcb or Gerber zip.
  • Automotive and industrial buses. STM32 bxCAN and FDCAN on multi-node buses, with arbitration, error counters and bus-off (CAN bus simulator), and Modbus RTU over RS-485 (Modbus RTU simulator).
  • An open engine. The LabWired core is MIT-licensed; its labwired test CLI runs on your own CI runner (LabWired for CI).
