Welcome to Pants!

What is Pants?

Pants is a scalable build system for monorepos: codebases containing multiple projects—often using multiple programming languages and frameworks—in a single unified code repository.

Monorepos have many advantages, but they require appropriate tooling in order to scale. Pants provides this tooling.
