Apache Maven vs FASTBuild

Apache Maven is a free build tool for Java projects. It uses a project object model, or POM, and plugins to manage compilation, testing and documentation through a uniform build system. Maven manages dependencies, including transitive dependencies and automatic updates, and can download them from a central repository. Project metadata can produce outputs such as JARs, WARs and distributions. Maven can also generate project information, including changelogs, cross-referenced sources, dependency lists and unit test reports. Java or scripting-language plugins extend it, and it can work with source control systems such as Subversion or Git to manage tag-based releases. It runs on Windows, macOS and Linux. Maven 3.10 and later requires JDK 8 or above to execute, while toolchains can target other JDK versions. Its project layout is opinionated, so projects with unusual structures that cannot be reorganized may have to give up some Maven features or Maven itself. The software is distributed under Apache License 2.0; its listed plan costs nothing.

FASTBuild is an open-source build system for compiling software across Linux, macOS and Windows. It runs compilation work across worker threads, can reuse results from local or network caches, and can distribute builds among networked machines when their settings and worker setup are compatible. The maker says caching can accelerate compile times up to 10x. Some compiler settings do not support caching or distribution; FASTBuild handles affected objects without caching or builds them locally. Supported toolchains include MSVC, GCC, SNC, Clang, GreenHills, CodeWarrior and NVCC, plus syntactically compatible command-line compilers. It can combine C++ files into Unity or Blob builds, while allowing writable files to be built individually for quicker iteration. FASTBuild can generate Visual Studio and XCode project files. The maker describes it as a self-contained executable that needs no installation or dependencies beyond compiler tools. It is free, with commercial use and redistribution allowed under license conditions; the license provides the software without warranty. The listed current release is v1.20, released 26-Apr-2026.
