Buck is a multi-language build system developed and used by Meta Platforms, Inc. It was designed for building small, reusable modules consisting of code and resources within a monorepo.[4] It supports C++ (Objective-C, Swift), Shell, Java (Kotlin, Groovy), Python, Lua, OCaml, Rust, Go and other languages as source code input. It can produce binary outputs for a variety of target platforms including IOS, Android, .NET and Java VM runtimes. Buck is licensed under the Apache License 2.0.[3]

Buck requires the explicit declaration of dependencies and enforces this using a symbolic link tree. Because all dependencies are explicit and Buck has a directed acyclic graph of all source files and build targets, Buck can perform incremental recompilation, only rebuilding targets downstream of files that have changed. Buck computes a key for each target that is a hash of the contents of the files it depends on. It stores a mapping from that key to the build target in a build cache. If targets are deterministic functions of the contents of their dependencies, then this build cache can be shared between developers and continuous integration (CI) as Buck supports a HTTP Cache API.
