FruitOS is a lean Linux OS distribution for Raspberry Pi, developed based on Alpine Linux. The root filesystem only contains necessary files to provide OS core functions, and push the application files to containers.

FruitOS uses an immutable, A/B root partitions where an overlay ramdisk is mounted on top the SD card root partition to eliminate the risk of disk corruption whenever there is a sudden electric outage. This partition scheme allows over-the-air since the update is applied on an inactive root partition. FruitOS will able to recover from an update failure by booting to the backup root partition and cloning it onto the corrupted one.

Key features:

  • Support 32-bit (Zero, Zero-W, 1, 2, 3) and 64-bit (3, 3B+)
  • Immutable, A/B root partitions
  • Over The Air (OTA) update
  • Support Docker containers
  • Remote configuration management
  • Remote monitoring system
  • Peer-to-Peer secure update (beta testing)

FruitOS currently supports all kinds of Raspberry Pi boards ranging from Zero, Zero-W, 1, 2, 3, and 3B+. The OS image file can be downloaded from
