    How is this different from Wokwi.com? They’ve been doing for years, and have a large number of microcontrollers emulated.

    Hi HN,

    I’ve been working on esp32sim, an open-source ESP32 emulator that runs in the browser.

    The fun part of the demo is that there is no ESP32 involved — the firmware is executing in the emulator.

    The goal is to make ESP32 software easier to experiment with, test and simulate without always needing physical hardware connected.

    I made a short video showing it in action: https://youtu.be/waoWFilTWEc

    I’m particularly interested in feedback from embedded developers: what would an emulator like this need to support before you’d actually use it for development, testing or CI?
