RAUC (Robust Auto-Update Controller) is an open-source update client and host tool for embedded Linux systems that manages fail-safe, atomic, cryptographically signed firmware/software updates. It supports A/B redundant setups, multiple bootloaders, HTTP(S) streaming, and bundle creation and verification.

Use cases

• update firmware on embedded linux devices over the air
• create signed update bundles for an A/B root filesystem setup
• stream updates over https without intermediate storage on the target
• integrate OTA update management into a Yocto or Buildroot based device
• verify cryptographic signatures of firmware update packages
• perform atomic bootloader and partition updates on eMMC or UBI
• control update installation and progress from a custom application via D-Bus

When to choose

• you maintain embedded Linux devices needing fail-safe A/B or recovery updates
• you require X.509 signed and optionally encrypted update bundles
• you need support for diverse storage like SquashFS, UBI, eMMC boot partitions, or raw flash
• you want bootloader integration with u-boot, barebox, grub, or EFI
• you need a D-Bus API for application-level update control

When to avoid

• you need updates for non-Linux embedded platforms like RTOS or microcontrollers
• you want a fully managed cloud OTA service rather than a self-hosted update client
• your target is a desktop or server Linux distribution with package-based updates
