About Helicone

Helicone offers an AI gateway and observability platform that logs requests across model providers through one integration. What sets it apart is that teams get caching, rate limiting, cost analytics and prompt management without changing their model code. It is aimed at builders who need agents that stay observable, controllable and useful once real users and real data are involved every day.
