Your stats page is lovely, akdk7. Thanks for creating and maintaining it.
With the time you have available, one thing I would like to see is a live page of currently accessible, publicly searchable instances of YaCy. This would be useful for people who don’t want to install YaCy, but just want to search using the YaCy network. If there were an option on the page to submit your own instance with the webpage, that would be great. If YaCy integrated this that would be even better. Perhaps there is something in the “Principal” peers mechanism which could accomplish this. (Where is the documentation on uploading from YaCy to an FTP server, by the way?)
There are a couple of examples of Free Software code for this in other web based projects. For example, when the maintainer dropped out of invidious, this page was useful:
The Jitsi project has a page with similar functionality (Free or non-Free Java might be a possible thing to include)
