Open-source LLM observability platform and API gateway that provides cost analytics, request logging, caching, and rate limiting through a simple proxy-based integration requiring only a base URL change.
Helicone is an LLM observability platform and API gateway that provides cost analytics, request logging, caching, and rate limiting through a one-line proxy integration, with pricing starting free and scaling from $20/seat/month. It's designed for engineering teams running LLM applications in production who need cost visibility and operational controls without rewriting application code.
Helicone is built around a proxy-based architecture — you change your LLM provider's base URL to Helicone's gateway (e.g., replacing api.openai.com with oai.helicone.ai) and add a Helicone-Auth header. Every request is forwarded to the original provider, and Helicone captures full request/response metadata including token counts, latency, computed cost, and status codes. The proxy approach means there are no SDKs to install, no decorators to add, and no trace context to propagate — it works with any HTTP client library including requests, fetch, axios, or native SDKs from OpenAI, Anthropic, and others.

Yes, Helicone is good for analytics & monitoring work. Users particularly appreciate proxy-based integration requires only a base url change — genuinely zero-code setup for openai and anthropic users in under 5 minutes. However, keep in mind proxy architecture adds 20-50ms latency per request, which compounds in latency-sensitive agent loops with many sequential calls.
Yes, Helicone offers a free tier. However, premium features unlock additional functionality for professional users.
Helicone is best for LLM Cost Visibility & Spend Management: Teams that need immediate visibility into LLM spending across multiple models and providers without writing integration code — just swap a base URL and see real-time spend within minutes and API Cost Reduction via Caching: Applications with repetitive query patterns (FAQ bots, documentation assistants, classification tasks) where gateway-level caching can meaningfully reduce API costs by 20-50%. It's particularly useful for analytics & monitoring professionals who need proxy-based request logging.
Popular Helicone alternatives include Langfuse, LangSmith, Braintrust. Each has different strengths, so compare features and pricing to find the best fit.
