Choose Exa if
Developers and AI teams who need a fast, controllable web search and content layer for agents, RAG or research products.
- Free $10 monthly credit grant with no card required
- Lite search at $4 per 1,000 requests suits high-volume agents
- Highlights cut token usage and LLM costs compared with full pages
Look elsewhere if: Non-technical users who want a finished answer engine or chat app rather than an API (Perplexity, You.com).
Choose NitroStack if
Developers and product teams building custom MCP servers on their own APIs who want SDK, testing and hosting in one place.
- Covers the full MCP lifecycle from SDK to hosting and chat front end
- Free hosting tier and open-source SDK
- Low $30 Pro plan priced per organization, not per seat
Look elsewhere if: Teams that only need MCP servers generated from an existing API spec as part of SDK tooling (Speakeasy).
