BuildXL is Microsoft's high-scale build engine that accelerates large monorepo builds through distributed execution and massive caching of sources and outputs. It supports JavaScript, MSBuild, Ninja/CMake, and its own DScript build language via a command-line interface.

Use cases

  • speed up builds of huge monorepo codebases
  • distribute build work across many machines
  • cache build outputs to avoid redundant compilation
  • accelerate JavaScript, MSBuild, or CMake/Ninja builds
  • sandbox build process executions for correctness

When to choose

  • you build very large monorepos where build time is a bottleneck
  • you need distributed builds and petabyte-scale caching
  • your team already uses or can adopt DScript or supported frontends

When to avoid

  • you want a simple small-project build tool
  • you need Visual Studio IDE integration
  • you expect a drop-in MSBuild replacement
