Comparison
Both are interactive web-based simulators, but they take fundamentally different approaches. Wokwi is mature and runs entirely in your browser. Simulator86 trades local portability for accuracy and depth. Here's how they stack up.
| Feature | Simulator86 | Wokwi |
|---|---|---|
| Component Library | Curated and growing — every component simulated deeply enough to debug against | Broad — many MCUs, sensors, and peripherals |
| Execution Environment | Dedicated server hardware — speed isn't limited by your laptop | Your browser tab (WebAssembly) — portable, but bounded by it |
| Simulation Accuracy | Instruction-accurate — fidelity is never traded for frame rate | Approximate — accuracy is what gets cut to stay responsive client-side |
| Interactivity | Interactive 3D inputs, scriptable | Clickable 2D components, predefined interactions |
| Development Environment | A real Linux environment — GCC, LLVM, vendor SDKs, anything that builds firmware | Arduino-style editor; Arduino and MicroPython only |
| Multi-Node Simulation | First-class — wire multiple boards into one running simulation | Single board only |
| LLM Integration | Native — the agent reads every register, memory address, and output, live | Bolted on from outside, via MCP |
Choose Simulator86 when you're shipping production firmware on advanced MCUs, need multi-node simulation with other team members, or want LLM agents that can inspect every register and memory address in real time.
Quick experiments, hobbyist work, ESP32/AVR tinkering. If you need a wide component library and zero setup in the browser, start here.
Bring us one firmware build and the failure your team cannot reproduce.
We’ll scope the virtual system, run the scenario, and show your team the evidence Simulator86 can preserve and replay.
