Yocto Project
What Yocto Project is
The Yocto Project provides templates, tools, and methods for building custom Linux-based systems for embedded deployments, servers, and virtual environments. Its build system combines OpenEmbedded-Core and BitBake, with Poky as a reference configuration. The Layer Model lets developers share, reuse, and customize repositories of build instructions. Builds can fetch source from tarballs or Git repositories, apply patches, run quality checks, and produce package feeds and filesystem images. Integrated tooling supports security analysis, license compliance, and SPDX software manifests. The project is designed for custom systems across hardware architectures and is listed for Linux and self-hosted use. Poky is a working example and customization starting point, not a product distribution, and contains no binary files. Most developers use a Linux development host. Yocto 6.0 Wrynose is listed as LTS until April 2030, while 5.0 Scarthgap is LTS until April 2028. The project is free and operates under the Linux Foundation umbrella.
