Decentralized Web Search
Web Search Engine Software
YaCy is free software for your own search engine. Join a community of search engines or make your own search portal!
There are these three use cases you can choose from:
Web Search by the people, for the people: decentralized, all users are equal, no central, no search request storage, shared index.
Your Search Portal
Your YaCy installation is independent from other peers. Define your own web index and starting your own web crawl.
Create a search portal for your intranet or web pages or your (shared) file system.
Imagine if, rather than relying on the proprietary software of a large professional search engine operator, your search engine was run by many private computers which aren't under the control of any one company or individual. Well, that's what YaCy does!
