Would you use a service that automatically identifies refactoring opportunities in your code? (feddit.org)

Hey,

I’m exploring the idea of a webpage where you can paste a function (or a block of code) in any programming language, and it outputs a list of specific, actionable refactoring suggestions - things like:

  • Unnecessary complexity
  • Poor naming conventions
  • Duplicated logic
  • Violations of language-specific best practices
  • Readability issues

The goal is to help developers quickly spot areas for improvement and make their code cleaner, more maintainable, and easier to understand.

Questions for you:

  • Would you use such a tool? Why or why not?
  • What features would make it important for you? (e.g., integration with GitHub, support for obscure languages, explanations for each suggestion, etc.)
  • Are you ready to pay for a tool like this (for example, paying for access to advanced checks or being able to tune checks for your programming style)?
  • Are there existing tools you love (or hate) that do something similar?

Just because a product exists already doesn't mean there isn't opportunity for a competitor! You could try competing on price, maybe offer a more generous free tier which can help you get more sign ups. Maybe make it free for self-hosting, but you make money offering it as a service as most devs probably won't bother.

Sonarqube proved there's a market for this type of product already, which is the hardest part!
