In their own words
distcc
distcc is free software that distributes C, C++, Objective C, and Objective C++ builds across networked machines. It sends preprocessed source code to machines running the distccd daemon and a suitable compiler. The project says distributed builds should match local results and are usually faster than compiling locally. distcc works with GNU Make, SCons, and other parallel build tools. Machines with different processors or operating systems can participate when suitable cross-compilers are installed. GCC is fully supported; Intel icc is somewhat compatible, and the FAQ reports Sun’s proprietary compiler working in C mode. The project is developed on GNU/Linux and reports use on several Unix-like systems, Cygwin, and BSD/OS; listed platforms include Linux, macOS, self-hosted use, and Windows. TCP transmissions are neither encrypted nor signed, while SSH connections are authenticated and encrypted. The FAQ says distcc does not automatically find the best work distribution. Related tools cover server selection, control, cross-compilation, and monitoring.
FASTBuild
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.
