Clean, Code through interactive refactoring, katas, Master

Stop reading about Clean Code and start writing it. We’ve all read the books, but applying SOLID principles or DRY in real-world messy code is a different story. Cleankata is an interactive platform designed to bridge that gap. Why Cleankata? Hands-on practice. Curated Katas: Exercises focused on specific smells (long methods, primitive obsession, nested conditionals). Instant feedback: See how your changes improve code maintainability and readability.

Hi everyone! I’m the creator of Cleankata. I built this project because I noticed a common pattern in our industry: many of us read books like "Clean Code" or "The Pragmatic Programmer", but when we face a messy, real-world legacy file, we don't always know where to start. Theory is great, but refactoring is a muscle that needs to be trained. Cleankata is my attempt to create a "gym" for developers. A place where you can: Get your hands dirty with real refactoring exercises. Internalize SOLID and DRY principles by actually applying them. Level up your code quality without the fear of breaking a production environment. The platform is completely free and I’m constantly working on new katas. I’d love to hear your thoughts: Which refactoring patterns would you like to see next? Is the difficulty level right for you? I’ll be here all day to answer your questions and chat about code quality. Thanks for checking it out!

Why mastering Clean Code is more critical than ever in the AI Era

I created Cleankata because we are entering a new paradigm: AI-driven development.

Today, tools like Copilot or ChatGPT can write code in seconds, but they often produce "working" code that is architecturally messy, hard to test, or full of subtle technical debt. To get the best out of AI, you need to be a great editor, not just a prompter.

If you don't know what "Clean Code" or "SOLID" looks like, you can't guide the AI to produce high-quality, maintainable software. You will simply end up with a faster way to create legacy code.

Cleankata is designed to train that "architect's eye." By practicing these katas, you develop the muscle memory needed to:
