FASTBuild vs Rake

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.

Rake is a Make-like task runner written in Ruby for defining tasks and their dependencies. Its Rakefiles use standard Ruby syntax, and tasks can declare prerequisite tasks. Rule patterns can generate implicit tasks, while FileLists provide array-like handling for file names and paths. Rake includes packaged tasks, including tasks for building tarballs, and can execute tasks in parallel. The documentation’s example has a default task call a test task that runs a Ruby unit test file. Rake runs on Linux, macOS, and Windows; the project lists Ruby 2.0.0 or later as a requirement. Installation is with `gem install rake`. Rake is free under an MIT-style license, with a listed plan of free. The project credits Jim Weirich as its original creator and Hiroshi SHIBATA as maintainer of Rake 10 and later. It is provided as is, without express or implied warranties.
