I'm also using Docusaurus for Fugu (https://docs.fugu.lol).

One thing that bothers me is that they offer a free Algolia integration for open-source projects, but they declined my application despite being open source.

So, search not working for now, need to have another look at that :-)

Edit: I just got an email from Algolia DocSearch saying that my documentation qualifies after all :-) If someone from that team read my comment and send the email, thanks! If not, it's a big coincidence, also good!
