pepr

pepr is a type-safe Kubernetes middleware framework designed for developers who want to write admission webhooks and mutating policies in Go with strong compile-time guarantees. It simplifies building custom Kubernetes controllers and operators by providing a declarative, human-friendly API that reduces boilerplate and runtime errors. Its interesting because it combines the safety of TypeScript-like type systems with the operational power of K8s middleware, making complex cluster logic more accessible and reliable.
