LiteLLM Gateway

LiteLLM's proxy gateway server provides a production-ready OpenAI-compatible API endpoint that routes requests across 100+ LLM providers with cost tracking, rate limiting, load balancing, fallback logic, and caching built in, enabling engineering teams to manage LLM provider access centrally without distributing API keys across services. Its budget management features enforce per-user and per-team spending limits, while its logging integrations capture detailed usage analytics for cost attribution and optimization. Platform engineering teams managing LLM access across multiple teams and applications use LiteLLM Gateway to standardize LLM access, control costs, and maintain flexibility to switch providers without application code changes.
