Sparrowgate
Open-source AI API router to prevent cloud billing leaks
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.
Hey Product Hunt!
Whenever I built something on cloud infra and AI APIs, one fear always stayed with me — waking up to a shocking bill I never saw coming. This kept bugging me over and over, so I decided to build a fix for it myself.
Sparrowgate was built for exactly this problem — a simple, open-source router that checks your traffic and smartly routes it across AI providers, so costs stay low and your bill never blows up out of nowhere.
What makes it stand out:
Fully open-source, nothing hidden
Smart routing that helps cut costs
Protection against sudden traffic or billing spikes
Check out the GitHub repo and let me know what you think — or if you've got ideas on how to make cost control even better, I'd love to hear them.
