LiteLLM review
A complete open-source gateway for multi-provider routing, controls, and observability.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
LiteLLM is an open-source LLM gateway and Python SDK for platform teams and developers managing access to multiple model providers. Its OpenAI-compatible API translates requests to provider endpoints, while routing, retries, fallbacks, virtual keys, budgets, rate limits, spend tracking, logging, and observability support shared model access. It is available through the web, API, and self-hosted deployments, with Docker, Helm, and Terraform options, including air-gapped deployments.
The Open Source plan is free forever and includes access to 100+ providers through one OpenAI API, virtual keys, users and teams, spend tracking, budgets, rate limits, LLM fallbacks, and request/response logging. Supported integrations include OpenAI, Anthropic, xAI, Vertex AI, NVIDIA, HuggingFace, Azure OpenAI, Ollama, OpenRouter, Novita AI, and Vercel AI Gateway. For teams operating several providers or deployments, provider and deployment routing, retry and fallback logic, Prometheus metrics, and observability callbacks provide a broad control layer without requiring a provider-specific interface.
Enterprise adds SSO and SCIM, OIDC/JWT authentication, audit logs, secret managers and key rotation, a multi-region control plane, 24/7 support, and SLAs. Its pricing is custom, so organizations should evaluate the governance and support requirements alongside the free forever Open Source plan. LiteLLM fits teams that want self-hosted control, centralized usage management, and routing across multiple LLM providers. Teams seeking only a direct connection to one provider may find its gateway, access-control, and operational features broader than necessary.
