Use Cases & Benefits
- Provides a Go-based SDK and framework for building Kubernetes APIs using custom resource definitions (CRDs).
- Reduces boilerplate and complexity by offering high-level abstractions and code generation for Kubernetes API development.
- Use for rapidly scaffolding and developing Kubernetes controllers and APIs with built-in testing and deployment workflows.
- Use for extending Kubernetes with custom resources and admission webhooks following canonical Kubernetes patterns.
- Use for integrating Kubernetes API development into other projects or operator frameworks via its plugin architecture.

From the README
Kubebuilder is a framework for building Kubernetes APIs using custom resource definitions (CRDs).
Similar to web development frameworks such as Ruby on Rails and SpringBoot, Kubebuilder increases velocity and reduces the complexity managed by developers for rapidly building and publishing Kubernetes APIs in Go. It builds on top of the canonical techniques used to build the core Kubernetes APIs to provide simple abstractions that reduce boilerplate and toil.
Kubebuilder does not exist as an example to copy-paste, but instead provides powerful libraries and tools to simplify building and publishing Kubernetes APIs from scratch. It provides a plugin architecture allowing users to take advantage of optional helpers and features. To learn more about this see the Plugin section.
Kubebuilder is developed on top of the controller-runtime and controller-tools libraries.
Kubebuilder is extensible and can be used as a library in other projects. Operator-SDK is a good example of a project that uses Kubebuilder as a library. Operator-SDK uses the plugin feature to include non-Go operators e.g. operator-sdk's Ansible and Helm-based language Operators.
