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?
- Are you aware of sonarqube? - It does the complexity and best practices parts of your list, and can be plugged into continuous delivery systems. Jetbrains’ IDEs have a free plugin that will run it locally, and I would be surprised if similar integrations didn’t exist for (neo)vim, vs-code, etc. - It’s pretty decent at explaining why it considers a chunk of code to be problematic, and can even propose quick fixes as if it were an LSP. - You can also flag issues it finds as “intended/deemed non-fixable by the dev(s)”. - I use this at work. It’s actually quite good. Its suggestions aren’t the sort of thing you’d ignore. - It does slow the IDE on large projects though. 
- Hi, hmm, I think that’s almost the tool I had in mind. So if sonarqube exists, I guess there is no need for another tool in the same area. Thanks for sharing - You’re welcome! I would suggest giving it a try, maybe there’s a feature or functionality you have in mind that sonarqube doesn’t do. 
- 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! 
 
- 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. 
 
- This has been a feature in IDEs since like 2000. - Hi, can you share an example? - Im not OP but I use VS Code and it’s setup to: - perform a static code analysis
- auto format code according to my defined code style
- highlight unused variables, namespaces, etc.
- make some suggestions to improve code quality
 - Which is what I think OP is trying to say. Your idea sounds like what IDEs should do (and mostly do). 
 
 
- JetBrains and Cursor do that already but better and without pasting anything. I’m sure it also exists with Copilot, Claude or ChatGPT. - Hello, please, see my comment -> https://feddit.org/post/20205034/9426357 
 
- Should be incorporated to my editor or some CLI reporting tools. 
- Are there existing tools you love (or hate) that do something similar? - This sounds similar to “Static code analysis” tools. Especially now that these code analysis tools are getting AI integrations. - For example we use coderabbit.ai. That does a code review on PRs in github, and reviews these sort of things. Especially the simpler things that you’ve mentioned like poor naming conventions, violations of language-specific best practices, and readability issues. I’m not sure if it will automatically come up with “large refactoring opportunities” by default - but maybe you can custom-prompt configure it to try, I guess - (Comment) Why have a separate webpage if such of helper can be built into IDE/editor? - Coderabbit also has IDE extensions: https://www.coderabbit.ai/ide - I think the separate webpage exists for org level configurations and overviews. These “best practices” are probably defined on a team level to ensure everyone uses the same code-style and things like that - I’m not sure if “just a website to copypaste code and get reviews” is really a good idea. Maybe for juniors that want to review one class or method or something. But usually code is spread across multiple files, and structural refactor opportunities are on a larger scale then just a couple files - Hi, thanks for sharing the info, appreciated 
 
- Make an open source project for this. I’d love something like this for neovim. Not that I ever have any novel code to leak but I still find it odd that we just invite businesses to just spy on our code. 
- @YUART what would be tje difference to do it with Zed or Avante (nvim) directly? I already ask sometimes to my editor for refactor a code. I also somtimes copy and paste it to Lumo (from proton) - I believe those are tools that use general-purpose LLMs, which aren’t tuned for refactoring specifically. So I guess a specifically tuned tool for refactoring will beat those you mentioned in refactoring tasks. - I also imagine a tool that is not AI-driven. While AI will be used for sure for some checks, I believe static checks and other “computable” heuristics will produce better output faster. I don’t want to throw a bunch of prompts into AI and sell mediocre-quality software to people. - But overall, I think about what you said, but from another perspective - why have a separate webpage if such of helper can be built into IDE/editor? I think this is harder to do than to create a webpage, but maybe this will be better for users (developers). - @YUART yes too, i thibk will be hard to hace another tab just for that purpose. And for refactoring you must know what refactor, I mean, I know when a name is no the best or the code was repeated or a code produce a n+1 problem, so when I ask for refactor to an LLM I make a specific query and not just: refactor it - That’s true, and that’s a hard part. I have some ideas on how to solve that problem, but I can’t prove anything because this is the first time I’m working on a helper like that one. - That’s also the reason why I decided to ask people - there is no point in engaging in complex problem-solving, like for that tool, to only find out that no one actually needs it 
 
 
 
- So it’s basically AI - Hi, not really. Please, see my comment -> https://feddit.org/post/20205034/9426357
