Why look beyond Respan?
Respan is the AI router with built-in observability and automated evals, built for teams running AI agents and LLM apps in production. Its LLM gateway gives you one OpenAI-compatible API for 1,000+ models across every major provider, and switching models is a one-word change.
Common reasons users explore alternatives
- Additional latency (30-40ms) from routing through a gateway layer
