About Yacy
Yacy is a free, open source search engine software that operates on a peer-to-peer network. Instead of relying on a central index, each Yacy instance crawls and indexes web pages independently, then shares results with other peers. This makes it resistant to censorship and single points of failure. You can run it on your own hardware to search the public web or build a private search index for an intranet.
Written in Java, Yacy runs on Linux, Windows, and macOS. It includes a built-in web crawler, a search interface, and a peer-to-peer protocol for exchanging index data. You can configure crawling rules, manage blacklists, and set up remote administration. It supports full-text search, faceted filtering, and ranking based on page relevance and peer trust.
Yacy is maintained by the Yacy Search Engine Project and is distributed under the GPL. It is ideal for privacy-conscious users, organizations wanting internal search without third-party services, and anyone interested in a distributed alternative to centralized search engines. The project has been active since 2004 with a small but dedicated community.
