Sparrowgate

什么是 Sparrowgate ？

Sparrowgate is a lightweight, open-source proxy router that protects you from unexpected cloud and AI billing shocks. It checks incoming requests and routes them across different AI providers based on cost and availability. As usage nears its limit, it automatically applies a cap — so your bill never crosses the line. Built for developers and startups who want to keep their server/API costs under control, without getting locked into a single provider.
