Helicone
Open-source LLM observability proxy for monitoring, evaluating, and optimizing cost and latency across providers with response caching and intelligent routing.
Our Take
Helicone provides a one-line proxy integration that captures every LLM request for cost analysis, latency tracking, and evaluation. It maintains the largest open-source API pricing database covering 300+ models, making it straightforward to benchmark Cost Per Feature across providers. Response caching can reduce costs by 15-30% on repeated queries, which is especially valuable in agentic workflows where agents re-issue similar prompts. Helicone is Apache 2.0 licensed and has been fully self-hostable since May 2025, giving teams full control over their observability data.
