Show HN: Esp32sim โ Run ESP32 firmware in the browser
17 October 2026 at 13:51
Hi HN,
Iโve 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 โ 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
Iโm particularly interested in feedback from embedded developers: what would an emulator like this need to support before youโd actually use it for development, testing or CI?
