Buck2

Buck2 is an open-source large-scale build system developed by Meta, designed to provide a faster and more reliable way to build software projects. It is an improved version of its predecessor, Buck. One of the key features of Buck2 is its speed, which allows for significantly faster builds even when dealing with large workloads. The system also emphasizes reliability by enforcing hermetic rules and treating missing dependencies as errors. Additionally, Buck2 offers extensibility through the use of Starlark, allowing users to define their own rules as first-class citizens. With its speed, reliability, and extensibility, Buck2 can be a valuable tool for developers in various software development applications.
