how about jekyll? Lots of customization available.

Glad it worked. It looks like its for getting the big stuff while communityboost is designed to help find the small.

From the way I read it, you create a user for the tool so when you submit your instance, it can run on your instance. One of the users chosen at random is here https://discuss.tchncs.de/u/communityboost

You can read a discussion about it here https://pawb.social/post/4136386

I also came across https://github.com/Fmstrat/lcs

Edit: Looks like https://sh.itjust.works/u/iso might be the user behind it.

There is a tool I’ve heard about that subscribes to remote communities for federation until a real subscription. https://boost.lemy.lol/
