LiteLLM

Open-source LLM gateway with cost tracking, routing, and fallbacks.

  • + Cost tracking, budget alerts, and spend limits per project or user
  • + Fallback chains and load balancing across providers
  • − Broad surface area; many features to configure
  • − Some advanced features require the paid CloudUI tier

Portkey

AI gateway with caching, fallbacks, and observability.

  • + Caching and fallbacks that survive provider outages
  • + Unified logging across all providers in one dashboard
  • + Self-hostable gateway with a managed cloud option
  • − Newer ecosystem than LiteLLM
  • − Managed cloud is the revenue layer; OSS is the gateway core
