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?

I love SonarQube (previously called SonarLint). I/We use it at work in dotnet/C# and web/Blazor projects.

Their free offer is great.

The dotnet and Visual Studio analyzer suggestions are already a great tool. Adding SonarQube on top, and recently I've added Roslynator Analyzers as well gives great free tooling, linting, suggestions of various levels, and quick actions to apply.

With the commercial backing they have, SonarQube is very well maintained/developed as well, with regular updates.
