Description
Respan is an AI observability and evaluation platform designed to help teams monitor, test, and optimize AI agents at scale. It provides deep execution tracing across conversations, tool invocations, routing logic, memory states, and final outputs. Rather than stopping at basic logging, Respan creates a closed-loop system that links monitoring, evaluation, and iteration into one workflow. Teams can define stable, metric-driven evaluation frameworks focused on performance indicators like reliability, safety, cost efficiency, and accuracy. Built-in capability and regression testing protects existing behaviors while enabling controlled experimentation and improvement. A dedicated evaluation agent uses AI to analyze failed trials, localize root causes, and suggest what to test next. Multi-trial evaluation accounts for non-deterministic outputs common in modern AI systems. Respan integrates with major AI providers and frameworks including OpenAI, Anthropic, LangChain, and Google Vertex AI. Designed for high-scale environments handling trillions of tokens, it supports enterprise-grade reliability. Backed by ISO 27001, SOC 2, GDPR, and HIPAA compliance, Respan delivers secure observability for production AI systems.
