YaCy is a full search engine application in Java that combines a web crawler, a search index server, and a web front-end. It can run standalone for personal or intranet search or join a decentralized peer-to-peer network where peers share a distributed search index.

Use cases

  • run my own web search engine
  • build a private search portal for my intranet
  • search the web without being tracked
  • join a decentralized peer-to-peer search network
  • index my organization's shared file system and web pages
  • self-host a Google alternative
  • crawl and index specific websites

When to choose

  • you want a self-hosted, privacy-focused search engine with no central provider
  • you need an intranet or enterprise search appliance without commercial licensing
  • you want to participate in or run a distributed P2P search index
  • you need a built-in crawler, scheduler, and search UI in one package

When to avoid

  • you need Google-quality relevance for general web search at scale
  • you want a lightweight embedded search library rather than a full server application
  • you need a managed cloud search service
  • you cannot run Java 17+ on your infrastructure
