Open-source AI gateway and observability layer for LLM teams to route, trace, and cost-track requests with a one-line integration.

What it does

Helicone is an open-source AI gateway and LLM observability platform that AI companies use to route, debug, and analyze their applications. It provides request monitoring dashboards, sessions, user analytics, custom properties, and HQL (a query language), plus prompt management, a playground, datasets, scores, and webhooks for testing and improvement. Gateway features include caching, rate limits, and automatic fallbacks. Helicone integrates with providers such as OpenAI, Anthropic, Azure, LiteLLM, Anyscale, Together AI, and OpenRouter, and offers HIPAA and SOC-2 Type II compliance on higher tiers.

How to use: Integrate Helicone with a single line of code to access cost tracking, agent tracing, prompt management, and more. Use the dashboard to monitor requests, segments, sessions, properties, and users. Improve prompts using the playground, experiments, and evaluators.
