kx is a flexible and extensible command-line framework, designed to help developers build and manage their own CLI tools under a unified entry point.
In addition to providing a solid foundation for custom commands, kx also comes with several built-in commands for common automation and data processing tasks, such as web data fetching, cookie management, and JSON-to-CSV conversion.
- Developers who need a lightweight, Kotlin-based CLI framework to organize internal tools.
- Teams looking for a unified way to expose multiple automation tasks under a single entry point.
- Data engineers and automation specialists who need ready-to-use commands for fetching, transforming, and processing data.
- Anyone who wants a flexible, extensible CLI framework.
