Sifthound

Sifthound is an open-source, self-hosted web search and extraction API that replicates the Tavily API, enabling AI agents and large language model apps to perform web search, content extraction, site crawling, and site mapping on your own infrastructure. It integrates with SearXNG for metasearch results and supports downstream AI integrations such as LangChain and Claude MCP clients, providing a privacy-oriented, MIT-licensed alternative to proprietary hosted services.
