I wrote Helium https://github.com/geuis/helium-css a while back to help find unused css on a site. The process of building sites has changed a lot since then so it’s not as universally useful as it used to be. (...Glares at React...). Joking aside, it’s had a good run. I’ve had some ideas for a few years about an updated version but it would really be an entire new project. Also created https://jsonip.com. Get your IP address in a json object. I created it a decade ago to solve some problem I had and have been running it ever since. Last I checked it’s supporting 4-6 million requests per day from a pretty wide group of users.
