Helicone review
A broad LLM monitoring stack with gateway, tracing, evaluations, and self-hosting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Helicone is an LLM observability platform and AI gateway for developers and teams building AI applications. It routes, logs, traces, and analyzes model requests through dashboards for requests, sessions, users, prompts, datasets, alerts, and cost analytics. Its scope also covers prompt management, evaluations, agent workflows, and vector database interactions, making it suited to teams that need both operational visibility and model-routing controls.
The plan structure gives smaller projects a free entry point. Hobby includes 10,000 free requests, 1 GB of storage, 1 seat, and 1 organization. Pro costs $79 per month and adds unlimited seats, alerts and reports, and the HQL query language; usage-based pricing applies. Team costs $799 per month and adds 5 organizations, SOC-2 and HIPAA compliance, and a dedicated Slack channel, with usage-based pricing also applying. Enterprise provides custom-built packages, a custom MSA, SAML SSO, on-prem deployment, and bulk cloud discounts. A 7-day free trial is also available.
Helicone’s ecosystem fits applications that use OpenAI, Anthropic, Azure, LiteLLM, Anyscale, Together AI, or OpenRouter, while LangGraph supports agent workflow tracing and Ragas supports evaluation integrations. The platform can expose an OpenAI-compatible gateway for 100+ models, track costs, apply rate limits, send alerts, and use automatic fallbacks. Docker supports self-hosting. Teams wanting one layer for observability, gateway routing, prompt workflows, and evaluation should consider Helicone. Smaller users with simple logging needs may find the paid usage model and broad feature set more than they need.
