Why Scavio Wins
- Six-platform search in one API key means your OpenWebUI instance grounds answers with Google, Reddit, and YouTube data simultaneously
- At $0.005/query with no self-hosting, total cost of ownership beats SearXNG once you factor in server maintenance time
- SearXNG wins for privacy-maximalist setups where no data leaves your infrastructure and you have DevOps capacity to maintain it
- Tavily wins when built-in content extraction matters more than platform diversity, especially for long-form research queries
- Scavio does not extract page content inline; if your OpenWebUI workflows depend on full-text extraction in search results, Tavily is the better fit
