Miraheze seems to be offering a platform to create private wikis and it runs the same software as Wikipedia. You do need to fill out a form and request a wiki but after that you and people you specify should be able to see and edit that wiki (with the exception of the main page which can be seen by everyone).

The people over at https://miraheze.org/ have been kind enough to host a wiki for us to upload our lore onto. Source: about 1 year ago

For those looking for an alternative to fandom https://miraheze.org is a good choice. Not for profit and they use vanilla mediawiki (what wikipedia uses) instead of whatever abomination fandom has going on. Source: over 1 year ago

For file transfers over the internet, https://wormhole.app/ and https://toffeeshare.com/ are often suggested. - Source: Hacker News / 3 months ago

Isn’t https://wormhole.app/ the solution here? Note I haven’t used it, it’s just often brought up here as a good solution for this class of problem. Is it surprising that the author mentions a ton of solutions but not this one? - Source: Hacker News / 4 months ago

One of the two creators of https://wormhole.app here :) Now that we’ve shifted our company’s focus to https://socket.dev, I’d love to open source Wormhole. I’m quite proud of the code - I’ve worked on P2P and file transfer systems for so so long that I think this might be some of the best code I’ve worked on. It’s just a matter of finding the time, but I expect this will be open source eventually. - Source: Hacker News / 5 months ago

It's unfortunately not FOSS, but I quite like https://wormhole.app/ - It's client side encrypted and P2P when possible. - Source: Hacker News / 5 months ago
