I'm wrapping up my 2+ years of work on a browser-based version of EverQuest that plays itself: https://idlequest.net/
Also have some other cool browser-based 3d game projects listed here: https://brynnbateman.com/
I'm building AllZonefiles (https://allzonefiles.io), aiming to make it the best domain data platform on the internet.
It covers 380M+ domains, with daily domain lists, additions/removals, and zonefiles with nameserver data. I recently added statistics for most zones, including domain counts and growth trends.
You might be surprised by what people build with domain data.
A job postings index built from employers' own applicant tracking systems instead of job boards. It polls about 17,000 public Greenhouse, Lever, Ashby, Workday, SmartRecruiters and Workable boards (hourly, Workday daily), dedupes them into one schema (parsed salary, seniority, remote/region), and keeps closed jobs with a closed_at date, so you can see how long roles really stay open. The fiddly part has been Workday: 20 jobs per page, and the total count only appears on the first page.
Disclosure, it's mine and it's paid per job returned: https://apify.com/cleanrowdata/fresh-jobs-index. Next up is per-company hiring rollups. Curious which filters people would actually use.
