What is Respan?

Respan is an LLM engineering platform designed to help teams build and deploy reliable AI applications. It unifies observability, evaluations, prompt management, and an LLM gateway into a single platform, giving engineering teams full visibility and control over their AI workflows.

​
Key capabilities

  1. LLM Observability — Trace every LLM call end-to-end. Monitor latency, token usage, costs, and error rates across all your AI workflows.
  2. Evaluations — Run automated assessments on prompt and model changes to catch quality issues before they reach users.
  3. Prompt Management — Version, test, and deploy prompts collaboratively without code changes, with rollback and A/B testing support.
  4. Unified LLM Gateway — Route requests across OpenAI, Anthropic, Google, and other providers through a single interface with built-in load balancing, fallbacks, and rate limiting.
