alternative firmware
John Vishnefske's Rust firmware keeps stock Chi trading, adds contacts, a pet screen, a GATT service, LED sync across badges running it, Wi-Fi and BLE scans, and a host tool; its adopt command backs up the stock image first and restore puts it back. Some stock-interop features were still marked pending in the design notes on October 26, 2026.

community alternative firmware
Alternative Rust firmware for the Conagotchi by John Vishnefske, created October 24, 2026. It trades Chi with stock badges, saves contacts, shows an animated pet, adds a Bluetooth LE GATT service and synchronised LED patterns, and is driven by the badgectl host tool over the USB debug link. Its README says the stock files, radio key, and DOOM stay on the badge. The repository has no licence file.
