  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:

        
          P2P Mode
      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.
       
        
          Intranet Search
      Create a search portal for your intranet or web pages or your (shared) file system.
        
      



Decentralization
Imagine if, rather than relying on the proprietary software of a large professional search engine operator, your search engine was run across many private devices, not under the control of any one company or individual. Well, that's what YaCy does!
