An open-source tool suite to build reliable embedded Linux devices
with efficient and secure over-the-air update capabilities.
💡 TL;DR: Rugix (formerly Rugpi) is a suite of open-source tools to build and deploy reliable embedded Linux devices at scale with efficient and secure over-the-air update capabilities. Companies around the world use Rugix as a basis for their connected products. Currently, the tool suite consists of two main tools:
- Rugix Ctrl: On-device tool for installing over-the-air updates and managing state.
- Rugix Bakery: Flexible, user-friendly build system for bespoke Linux distributions.
While these tools are designed two work seamlessly together, they can be used independently. By providing a unified and efficient modern development workflow, Rugix enables better results at a lower cost.
Get started today! Build your first system and deploy an update, all in under 30 minutes! 🚀
Rugix Ctrl has all features you would expect from a state-of-the-art update solution and more:
- Atomic A/B system updates with popular bootloaders out of the box.
- Streaming updates as well as adaptive delta updates out of the box.
- Builtin cryptographic integrity checks before installing anything anywhere.
- Supports any update scenario, including non-A/B updates and incremental updates.
- Supports any bootloader and boot process through custom boot flows.
- Robust state management mechanism inspired by container-based architectures.
- Integrates well with different fleet management solutions (avoids vendor lock-in).
- Provides powerful interfaces to built your own update workflow upon.
Rugix Ctrl supports or can be adapted to almost any requirements you may have when it comes to robust and secure updates of your entire system as well as its individual components.

You wrote your application and now need to integrate it into a full system ready to be flashed onto your device or deployed as an update? Rugix Bakery makes this process (almost) as easy as writing a Dockerfile, enabling you to focus on what provides value to your users instead of system-level details.
- Build upon proven distributions such as Debian and Alpine Linux.
- Over-the-air update capabilities powered by Rugix Ctrl out of the box.
- Build everything from source to image in a container-based environment.
- Define multiple system variants, including variants for testing.
- Builtin system testing framework and support for running VMs.
With Rugix Bakery, you get a comprehensive tool to build, test, and run your system similar to what you will find with modern software development tooling, like Cargo (Rust) or uv (Python).

Rugix has been started out of frustration with the current state of the embedded Linux ecosystem. While there are already tools for building images, updating systems, and managing state, integrating them into a robust, coherent solution remains a significant challenge. With Rugix, we aim to simplify the development of embedded Linux devices by providing a unified, modern suite of tools that seamlessly integrate to provide an efficient workflow for building, updating, and managing embedded Linux systems at scale. We believe that building embedded Linux devices should not be as complicated as it often is today.
While simplicity is our first key tenet, our second is to provide solutions that are absolutely robust. Embedded devices must stay operational no matter what, always, anywhere. With Rugix, we make it easy to follow best practices for building reliable devices, like read-only system partitions, fully atomic updates with on-device validation, and declarative, ideally fully reproducible builds.
