Refiner

Code quality matters, but manually refactoring messy code is tedious and time-consuming. Refiner is an open-source service that uses AI to help developers improve their code through intelligent refactoring and generation capabilities — making cleaner, better-structured code more achievable than ever.

What sets Refiner apart is its strong commitment to privacy: it does not retain any code you enter, and it avoids third-party analytics tools entirely. You get the power of AI-assisted code improvement without handing your codebase over to a black box. Open source, privacy-first, and built for developers who care about both.
