Feature-by-feature comparison
Verdict
DuckDuckGo is fine for development and prototyping where occasional failures are acceptable. For production agents, Tavily wins on reliability. For agents that need multi-platform data (not just web search), neither covers Amazon, YouTube, Reddit, or Walmart.
Consider Scavio instead
Scavio offers a middle ground: $0.005/credit (37% cheaper than Tavily), 250 free credits/month, multi-platform coverage (Google, Amazon, YouTube, Reddit, Walmart), and production-grade reliability. If DuckDuckGo is too fragile and Tavily too expensive per credit, Scavio fits between them.
