Helicone: Open-Source AI Gateway & LLM Observability

Helicone is an open-source, self-hostable AI gateway and LLM observability platform that gives developers a single OpenAI-compatible API to reach 100+ model providers with request routing, caching, rate limiting, and cost analytics. It's aimed at engineering teams and AI startups that need low-friction cost tracking and request logging — you change a base URL to start logging — rather than deep agent-workflow debugging. Its main differentiator is being an open-source, self-hostable gateway that unifies multi-provider access at 0% markup while doubling as an observability layer.
