Helicone AI

Helicone is an open-source observability platform designed to help developers monitor and optimise their large language model (LLM) applications. It provides visibility into LLM behaviour, performance metrics, and costs, making it easier to debug issues and improve reliability in production environments. The platform handles request routing, logging, and analytics for AI applications, allowing teams to track latency, token usage, error rates, and other critical metrics. Helicone is particularly useful for companies building AI features at scale, as it helps identify bottlenecks and reduce operational costs without requiring extensive custom instrumentation.
