Why the models rank LiteLLM — on best api gateways for ai and llm apis
“The de facto open-source standard for LLM gatewaying — a self-hosted proxy that normalizes 100+ providers to the OpenAI format with virtual keys, per-team budgets, rate limits, caching, fallbacks, and spend tracking; free to run, huge community, and it solves the exact problem (multi-provider routing + cost governance) most teams actually have. Assumption: the typical practitioner is a platform/ML engineer standing up an internal LLM proxy.”
Why the models rank Portkey — on best api gateways for ai and llm apis
“Best overall balance of a universal API, fallbacks, conditional routing, load balancing, retries, circuit breakers, caching, budgets, guardrails, and strong observability; near-tied with LiteLLM, but easier for a typical team to operate”
