What is Toaster?

Toaster is a web interface to configure and run builds. It communicates with the BitBake and Poky build system to manage and gather information about the builds, packages, and images.

There are two ways to use Toaster:

  • Locally: We can run Toaster as a local instance, suitable for single-user development, providing a graphical interface to the BitBake command lines and some build information.
  • Hosted: This is suitable for multiple users. The Toaster servers build and store the users’ artifacts. Its components can be spread across several machines when using a hosted instance.

In this chapter, we will use Toaster as a local instance. However, if you want to use it as a hosted instance, please visit the following website for instructions – Toaster Manual (
