Comparison
Simulator86 vs Wokwi
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 |
When to choose what
SIMULATOR86
When accuracy, depth, and AI integration matter
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.
WOKWI
Great for learning, prototyping, and Arduino-class projects
Quick experiments, hobbyist work, ESP32/AVR tinkering. If you need a wide component library and zero setup in the browser, start here.
Imagination is more important than knowledge.
