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 RunInfra if
Developers who use coding agents heavily and want open models at a flat, predictable monthly price.
- Predictable monthly cost from $10 for agent-heavy coding
- Drop-in for tools that already speak the OpenAI or Anthropic API
- Very low per-token prices on small and fast open models
Look elsewhere if: Teams that need the strongest closed models for complex coding work (Claude, ChatGPT Codex).
