Similar to the 512KB club, there exists the 250KB club. It collects web pages that focus on performance, efficiency and accessibility.
Qualifying sites must fullfil one requirement.
The website must not exceed 256KB compressed size.

256KB Club also contains very niche sites and is great to discover some new corners of the Internet.
The linked pages are often minimalistic personal pages and geeky blogs.

I submitted my blog for inclusion in the club, as it measures less than 250KB.
It was accepted a day earlier than for the 512KB club :-)
Now the blog has its own page in the club: https://250kb.club/blog-x-way-org/
