YaCy

Free, distributed peer-to-peer search engine software.

About YaCy

YaCy is free software for running your own search engine, built as a distributed peer-to-peer network rather than a central index. Every participant contributes crawling and indexing capacity, and users can also run private local search over their own intranet or files. Released under the GPL, YaCy appeals to people and organisations that want web search independent of centralised, advertising-funded providers.
