About Helicone
Helicone is an AI observability and gateway platform for teams building and operating LLM applications and AI agent workflows. It helps developers log requests, inspect multi step workflows, analyze application behavior, and monitor production performance.
The platform provides request logging, session tracking, user analytics, custom properties, cost and latency analysis, prompt management, datasets, playgrounds, scores, reports, alerts, and query capabilities. Teams can use Helicone with its AI Gateway or bring their own provider keys for observability.
Helicone AI Gateway provides a unified OpenAI compatible API for access to more than 100 models and providers. It supports intelligent routing, automatic fallbacks, caching, rate limits, and built in observability. Helicone can be connected through SDKs, proxy based integrations, or provider specific integrations.
