OpenWebUI + SearXNG vs API Backend Search
OpenWebUI's default search integration uses SearXNG, a self-hosted metasearch engine. API backend search replaces SearXNG with a managed search API (Scavio, Tavily, Brave) that returns structured results without self-hosting. The tradeoff is operational complexity versus per-query cost. SearXNG is free but requires maintenance. API backends cost money but eliminate infrastructure headaches. For teams running OpenWebUI in production, search reliability directly impacts user experience.

OpenWebUI + SearXNG
Free (both open source). Hosting costs only.
Strengths
- Zero per-query cost after initial server setup
- Full privacy: no search queries sent to third parties
- Customizable search sources and ranking
- Complete self-hosted stack with no external dependencies
Weaknesses
- SearXNG instances get rate-limited by upstream search engines
- Requires Docker setup, maintenance, and monitoring
- Result quality degrades when engines block the instance
- No structured SERP feature data (AI Overviews, etc.)
API Backend Search
Scavio: $0.005/query. Tavily: $0.008/credit. Brave: $0.005/query.
Strengths
- Reliable: managed service with consistent uptime
- Structured JSON results with typed fields
- No infrastructure to maintain beyond the OpenWebUI instance
- AI Overview and SERP feature data available (Scavio)
Weaknesses
- Per-query cost scales with usage
- Search queries sent to third-party API provider
- Dependent on external service availability
- Requires API key management
Feature-by-feature comparison
Verdict
OpenWebUI + SearXNG wins for privacy-sensitive deployments and teams with DevOps capacity willing to maintain the search infrastructure. API backend search wins for teams that prioritize reliability and minimal maintenance. In production, SearXNG's rate-limiting issues cause the most problems: when Google blocks your instance, users get empty search results with no fallback. API backends trade per-query cost for consistent behavior.
Consider Scavio instead
Scavio can replace SearXNG as OpenWebUI's search backend at $0.005/query. Configure OpenWebUI to call api.scavio.dev instead of a local SearXNG instance. The result is more reliable search with structured data, including AI Overview content, at a cost of roughly $50/mo for 10K queries. For teams tired of SearXNG maintenance, this is a direct swap.
