Buck2 — Large-Scale Build System for Software
Buck2 is an open-source large-scale build system for software engineering teams managing complex codebases
Buck2 is a large-scale build system designed to handle high-performance software compilation and testing. Built by Meta, this tool is specifically engineered for software development teams and organizations managing massive codebases with complex dependencies. The system improves upon previous build tools by utilizing a decoupled architecture that separates the build logic from the underlying execution engine. By implementing Buck2, companies can significantly reduce build times through its hermetic execution and advanced caching mechanisms. The tool supports multiple programming languages and integrates with remote execution services to distribute workloads across large server clusters. This ensures that developers spend less time waiting for builds to finish and more time writing code. You can find more technical resources and similar developer tools on surfai.app to optimize your 2026 engineering stack. Key features include a Starlark-based configuration language, which provides a familiar syntax for writing build rules without sacrificing speed. The tool is designed to be extensible, allowing teams to define custom rules that fit their specific project requirements. Its incremental build capability ensures that only the necessary parts of a project are rebuilt when changes occur, maintaining high speed even in multi-million line repositories. Buck2 is an open-source project available for free to all development teams.
