LiteLLM

Overview​

LiteLLM is an open-source SDK and self-hosted gateway that presents a common API across many model providers with routing, budgets, rate limits, fallbacks and logging. It reduces integration work, but centralizes keys and traffic in a critical component that must be hardened and updated carefully.

Best for​

Engineering teams needing one model API, provider routing, virtual keys, spend controls, fallbacks and self-hosted LLM gateway governance

Pricing and availability​

The open-source gateway is free to self-host, excluding infrastructure and model-provider charges. Enterprise licensing adds SSO, audit, support and advanced governance under annual quote-based pricing.

Platforms and integrations​

Available through: linux, api.

LiteLLM connects to numerous model providers and exposes OpenAI-compatible endpoints. It integrates with observability, secret-management, identity and deployment systems through proxy configuration and hooks.

Privacy and security​

Self-hosting keeps the gateway under customer control, but it concentrates provider keys, prompts and logs. Teams should pin reviewed versions, isolate the service, use vault-backed secrets, restrict logging and monitor security advisories and dependencies.

Key strengths​

• Common API reduces provider-specific application code
• Budgets, virtual keys and fallbacks support shared model access
• Open-source self-hosting enables infrastructure control

Key limitations​

• Gateway compromise can expose many keys and prompts
• Production operation requires upgrades, monitoring and secure configuration
• Provider feature differences can leak through the common interface
