The World Wide Web has brown into an ever so bloated mess of massive libraries, client-side scripts, and ever growing complex frameworks. The 99KB Organization is a one-man project started by Anton McClure, who was inspired by the 1mb.club, the 512kb.club, and the 250kb.club. Even though Anton had the option of calling it the 99KB Club, to fit in with their names slightly better, he does not like the "new TLDs" and he does not like using them. A good .org domain is also far cheaper than a .club domain name.
Because it would be unrealistic to have an entire web site fit in less than 100KB of space, only the listed web page needs to fit this criteria, but it would be best if all of your web pages would fit the eligibility criteria.
Getting listed is simple. Anton has a Git repository that you can clone with git clone https://www.99kb.org/sites.git. Once done, follow the instructions in the README file, and submit your new listing as a git-email patch to 99kb@next.gen.oh.us.
