🧪 Helicone: Open-Source LLM Observability Platform

Helicone is an open-source observability platform tailored specifically for Large Language Model (LLM) applications. As AI integrations scale, tracking API costs, latency, and response quality becomes a critical operational requirement. The hard part of LLMOps is extracting actionable analytics from raw API logs. Helicone simplifies this by requiring only a single-line change to the base URL to intercept and log all model requests. It provides comprehensive dashboards, prompt experimentation, and custom evaluation metrics. It is a robust infrastructure choice for teams moving AI applications from prototype to production.
