| Description | 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. | Vercel is the platform for frontend developers, providing the speed and reliability innovators need to create at the moment of inspiration. Built by the creators of Next.js, Vercel powers Nike, eBay, Mercedes-Benz, and millions of developers. |
