Overview
Helicone is an open-source AI gateway and LLM observability platform launched in 2023 through Y Combinator's W23 batch. It enables AI engineers to log, monitor, debug, and analyze LLM applications via a one-line code change that routes traffic through Helicone's proxy. The platform combines a unified AI gateway—providing access to 100+ models with intelligent routing, automatic fallbacks, and response caching—with full-stack observability covering request tracing, cost and latency analytics, prompt versioning, session tracking, and evaluation scoring. Available as a managed cloud service or self-hosted via Docker or Helm, Helicone supports major providers (OpenAI, Anthropic, Azure, AWS Bedrock, Google Gemini) and frameworks (LangChain, LlamaIndex, Vercel AI SDK). In March 2026, Helicone was acquired by Mintlify and transitioned to maintenance mode.
