ESP32 firmware is fully open source MIT — read it, fork it, improve it. don’t want to flash hardware yet? there’s a built-in simulator. EN / IT / DE. 1 cell is free. forever. no account needed to try the simulator. the docker backend needs a license key but we give those out for free during beta — just register. 👉 docker: github.com/jaffa2970/nestgrow-backend/releases/latest
