I got Ulanzi TC001 pixel clocks and flashed them with AWTRIX — an open-source ESP32 firmware. It kept crashing and rebooting. Dug into the code and found memory leaks, no tests, and a messy architecture. Forked it, fixed dozens of bugs, added tests, restructured into modules. Works with Home Assistant via MQTT with auto-discovery. Built an online flasher so you can flash directly from the browser.
