GreyFox – Free self-hosted AI proxy, token quotas, and local cache

GreyFox is a self-hosted AI proxy that provides token quotas and local caching for managing API usage across multiple AI services. It is designed for developers and teams who want to control costs, enforce usage limits, and reduce latency by caching responses locally. The project is interesting because it offers a free, privacy-focused alternative to centralized API management, giving users full control over their AI infrastructure.
