🧊 Open source LLM observability platform. One line of code to monitor, evaluate, and experiment. YC W23 🍓
Helicone is an open-source platform for monitoring and routing requests to large language models. AI engineers use it to inspect agent and application traces, track cost and latency, evaluate quality, manage prompts, and access multiple models through an API gateway. Catalogue add-ons support observability and LLM workflow tasks.
