Supergate

Enterprises using LLM providers face high API costs, lack of centralized rate limiting, and no unified way to attribute costs across multiple internal teams. They need a single, secure gateway to manage API keys, route requests, cache similar prompts semantically, enforce tenant-isolated RBAC, and mask PII — all while maintaining sub-millisecond overhead.

Supergate successfully reduces third-party LLM API costs by an estimated 40% on repeated prompt patterns through its pgvector semantic caching. It provides high-throughput routing with automatic fallback across five major LLM providers. The client SDK and Next.js analytics dashboard give engineering teams full visibility into cost attribution, rate-limiting statuses, and error rates in real time.
