Pants is a fast, scalable build system and developer workflow tool designed especially for monorepos containing multiple projects and languages. It orchestrates compilers, test runners, linters, formatters, and packagers into a hermetic toolchain with fine-grained invalidation, shared caching, and remote execution.

Use cases

• manage a monorepo with python, go, java, and scala projects
• run only the tests affected by my git changes
• get hermetic repeatable builds with dependency lockfiles
• speed up builds with caching and concurrent execution
• unify linting, formatting, and packaging under one command
• extend the build system with custom rules via a plugin api
• build aws lambda packages and docker images from a monorepo

When to choose

• you have a monorepo with multiple languages and interdependent projects
• you want minimal BUILD file boilerplate thanks to dependency inference
• you need fine-grained invalidation and shared result caching for speed
• you want a unified interface for tests, linters, formatters, and packaging
• supply-chain-resistant, lockfile-based hermetic builds matter to you

When to avoid

• you have a small single-language project where a simpler tool suffices
• your team is heavily invested in another build system like Bazel or Gradle
• you rely on languages Pants does not yet support
• you need a GUI-based build configuration experience
