What Is the Yocto Project? | Wind River
What Is the Yocto Project?
The Yocto Project is an open source project specifically for the embedded space. Whereas other Linux distributions are built for enterprise servers and workstations and then (possibly) tailored down for embedded use cases, the Yocto Project enables the build of customized distributions for embedded devices. In a disparate market with heterogeneous requirements, the project seeks to define a common ground for embedded development, independent of the underlying architecture of the hardware.
After more than a decade, the Yocto Project has evolved to become one of the largest communities under the Linux Foundation umbrella of collaborative open source projects. It gathers the top names in the industry, applies best practices for open source, and defines the attributes of embedded OS development and product lifecycles with the tools it offers.
The Yocto Project is a suite of tools and processes enabling the developer to build, from the ground up, an embedded Linux distribution on a broad set of hardware architectures.
Key Benefits of the Yocto Project
- Aggregates best-of-breed infrastructure, recipes, and tools for building a distribution
- Reduces duplication of effort
- Increases collaboration and reuse between commercial and open source communities
- Leverages the benefits of other open source projects, such as OpenEmbedded and Eclipse
Yocto Project Fast Facts
- In 2010, the Yocto Project was announced as a new work group under the Linux Foundation; Wind River® joined as a founding member.
- With more than 30 member companies, 2,500+ contributors to the Yocto Project have made over 170,000 (and counting) code commits, representing more than 11,600,000 lines of code.
- The Yocto Project is one of the largest open source teams in the world.
Difference Between Yocto Project Poky and OpenEmbedded
Poky is the reference operating system distribution built with Yocto Project tools, and OpenEmbedded is a build framework of recipes and packages. OpenEmbedded supports many hardware architectures with cross-compilation infrastructure. The community uses it to validate Yocto Project features and functionality, but it also serves as example for any user who builds their own custom distribution.
Yocto Project Contributing Companies
The project began with a dozen companies comprising major players in both hardware and software in the embedded market. Today the Yocto Project has more than 30 member companies, including AWS, Intel, Meta, Microsoft, and Wind River.

Differences Between Embedded Linux Distributions
Yocto Project vs. Ubuntu Core
Yocto Project is not a distribution — it is a set of tools to develop a distribution. Ubuntu Core is a Linux distribution delivered in binary.
Yocto Project vs. Buildroot
Buildroot is small and simple, and it gives quick results. Yocto Project needs more time to build the image and requires more disk space. On the other hand, its layers are easier to maintain and, because it’s a complex build system, it provides more possibilities.
Yocto Project vs. Debian
Debian, delivered in both source and binary, originated in the enterprise space for servers and workstations. The Yocto Project was created specifically to address embedded.
