FreeLLMAPI is an open-source LLM gateway that combines free tiers from multiple AI providers behind a single OpenAI-compatible /v1 endpoint.

It currently supports dozens of providers and hundreds of free model endpoints, with automatic routing, fallback when a provider hits rate limits, encrypted API key storage, and usage tracking for different free-tier limits. It can also connect to custom OpenAI-compatible endpoints.

The project can be self-hosted with Docker or used through its desktop app, and works with OpenAI-compatible clients and coding tools such as Claude Code, Codex CLI, Cline, Continue, Aider, Cursor, and others.

It is mainly intended for personal experimentation and prototyping rather than production workloads.
