Free LLM API

Overview / Description

Free LLM API is an open-source, OpenAI-compatible proxy that aggregates the free-tier access of roughly 16 LLM providers behind a single /v1 endpoint — about 1.7B tokens per month combined. It handles smart routing and automatic failover between services (and any custom OpenAI-compatible endpoint), with encrypted key storage, so you can experiment with many models through one interface. It's intended for personal experimentation only, not commercial use.
