Briefing
ESP32 boards run on a QEMU fork that covers the Xtensa LX6 and LX7 cores and RISC-V; AVR and RP2040 boards are emulated in the browser itself. The agent writes ESP-IDF, Arduino or MicroPython code. Besides the serial monitor, it can read simulated displays and press simulated buttons.
Velxio is licensed AGPLv3, with a commercial license on offer, and self-hosts as one Docker image. The Espressif article counts more than 30 boards; the current README says 40. The article does not describe exporting a build to a physical board.
