Developer Tools
These are the small utilities that don't belong in an IDE but get used constantly during development anyway — a JSON formatter to make an API response readable, a JWT decoder to check what's actually inside a token, a regex tester to figure out why a pattern isn't matching, a Base64 encoder for a quick one-off conversion. There are also generators for the boring-but-necessary files every site needs: robots.txt, sitemaps, crontab expressions. Nothing here requires an account or sends your data anywhere — it's meant to be faster than opening a new project just to run one function, which is really the whole point of a tool like this.
