jsonnet

brew install jsonnet v0.22.0 Apache-2.0

Domain-specific language and compiler for generating JSON configuration from reusable, parameterized templates.

Why you might care

Jsonnet eliminates JSON boilerplate through variables, functions, and inheritance, making it ideal for managing large cloud infrastructure configs (Kubernetes, Terraform) or API schemas at scale. It outputs pure JSON, so it integrates seamlessly into existing tooling. The single-binary compiler is fast enough for iterative development.
