Embedded teams can put real ESP32 binaries in CI without a board farm or a Wokwi subscription.
Esp32sim emulates ESP32 chips well enough to boot the mask ROM, bootloader and your unmodified app, with a JIT that runs hello_world about 30 times real time. It models specific boards, including displays, touch, LEDs, audio, camera and Wi-Fi that reaches the real network, and builds to WebAssembly for a live browser demo. The S3 is mature; C3 and C6 are drafts and classic ESP32 is early. MIT, from Joakim Eriksson at RISE and contributors.
