CrewAI agents use BaseTool or built-in tool classes to access external data. The default SerperDevTool covers Google only. Adding a custom search tool with multi-platform support gives your crew access to Reddit opinions, YouTube content, and Amazon products alongside Google results. We compared five search options for CrewAI builders.
Scavio works as a CrewAI BaseTool with multi-platform search (Google, Reddit, YouTube, Amazon, Walmart, TikTok) at $0.005/search, giving crews diverse data sources.

Why Scavio Wins
- Multi-platform search lets CrewAI agents gather Google results, Reddit opinions, and YouTube content in one research crew
- BaseTool implementation is about 20 lines of Python, adding six data platforms to any CrewAI workflow
- SerperDevTool wins for teams that only need Google search and want zero custom code with built-in CrewAI support
- Tavily wins for agents that benefit from extracted page content included with search results
- Scavio requires a custom BaseTool class since it is not built into CrewAI, adding ~20 lines of boilerplate
