LiteLLM (BerriAI) (litellm.ai) Review

LiteLLM is an open-source project by BerriAI that provides a unified interface to call over 100 LLM providers with the same input-output format. Its Python library and proxy server translate requests to OpenAI, Anthropic, Azure, Vertex, and many other backends, adding load balancing, fallbacks, rate-limit handling, spend tracking, and pass-through endpoints. The core library and proxy are MIT-licensed and free to self-host. A paid enterprise tier adds features like SSO and RBAC; enterprise pricing is quote-only, so no public starting price is listed.
