Respan

Respan is a comprehensive LLM engineering platform built for teams that need to build, monitor, and optimize AI agents without juggling disconnected tools. It brings observability, evaluations, prompt optimization, and a unified AI gateway together in a single interface, so your whole workflow lives in one place.

When something goes wrong in production, you can trace the full execution path of any agent to see exactly what happened. Measure quality the way that fits your team, whether that is LLM-as-judge scoring or human review, and manage prompt versions with confidence as you iterate.

Instead of wiring up different providers one by one, access more than 500 models through a single API endpoint. The platform is engineered for massive scale, handling trillions of tokens while maintaining rigorous security standards including SOC 2 and HIPAA compliance.
