About

Helicone is open-source LLM observability — drop in a proxy URL on your OpenAI/Anthropic SDK and get full request logs, cost tracking, prompt management, evals, and a query language for your traffic. Self-host the OSS edition for free or use the cloud tier. Most builders pick Helicone as their first observability tool because the integration is genuinely 1-line.

Best for: Solo and SMB builders who need basic LLM observability without enterprise pricing — the Hobby tier covers 10K requests free, Pro at $79/mo unlocks unlimited seats and HQL. Self-host for free if data residency is the constraint.
