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
