Helicone
Open-source LLM observability, caching, and rate limits
Helicone (helicone.ai) Review
Helicone is an open-source observability platform for LLM applications. A lightweight proxy or SDK integration logs every request, enabling dashboards for cost, usage, and latency, along with caching, rate limiting, user tracking, prompt experimentation, and evaluations. The free plan covers 10,000 requests per month without a credit card; paid plans start at $79 per month, with a Team tier at $799 per month. Because it is open source, Helicone can be self-hosted for full data control. It supports all major LLM providers through a single integration point.
