Side by side
GN vs Meson
Both stand on build automation software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxMacWindows
Choose GN if you need a meta-build system for Ninja and can select a version compatible with your project. Look elsewhere if your workflow depends on a stable version that guarantees backward compatibility across projects.

Meson combines a readable build-definition language with multiple backends, IDE integrations, and cross-compilation support. Account for its Python requirement and the Ninja dependency when using the default backend.
