How we rank these
One signal, honestly applied: GitHub stars, refreshed from the API when the site builds. It's a blunt measure — it favours older and open-source projects, and says nothing about whether a tool is right for you — but it's real, and you can check it yourself.
- GitHub stars
- Pulled from the API at build time for every tool with a repo.
- Hand-curated
- Every tool is reviewed before listing. Nobody pays to be here.
- Not a rating
- We don't score tools out of five. There are no reviews here to average.
