  • @eliasulrich Interesting! By reading that, I remember that #YaCy is still around, haven't had a look to this projects for over a decade, but I guess they made some progress, too :)

What “yacy” means

Wikipedia

YaCy is a free distributed search engine built on the principles of peer-to-peer (P2P) networks, created by Michael Christen in 2003. The engine is written in Java and distributed on several hundred "YaCy-peer" computers, as of September 2006.

#yacy across platforms

every network with a public tag surface

Follow #yacy straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/yacy
