Best LLM API gateway / router

Combined ranking

1. 1
   LiteLLM—18 pts

   GPT #1Claude #2Gemini #1Grok #2

   Best all-around gateway for serious multi-model apps: open-source, self-hostable, OpenAI-compatible proxy, 100+ providers, virtual keys, budgets, spend tracking, load balancing, retries, fallbacks, caching, guardrails, and strong enterprise deployment options

   To stay #1 Make the managed cloud experience as polished and trustworthy as the self-hosted core

2. 2
   OpenRouter▲115 pts

   GPT #3Claude #1Gemini #4Grok #1

   Largest unified catalog (400+ models across every major lab) behind one OpenAI-compatible API, transparent pass-through pricing, automatic failover and provider routing, and massive developer mindshare that makes it the default for shipping multi-model apps fast

   To rank higher Offer stronger enterprise controls (self-hosting/VPC deployment, granular compliance and data-residency guarantees) so larger companies don't graduate off it

3. 3
   Portkey▼114 pts

   GPT #2Claude #3Gemini #2Grok #3

   Strongest production control plane: universal API, advanced configs, conditional routing, nested fallbacks, load balancing, retries, circuit breakers, semantic caching, guardrails, observability, budgets, rate limits, and self-hosting

   To rank higher Simplify the developer experience so basic routing feels lighter and less config-heavy

4. 4
   Cloudflare AI Gatewayincumbent—6 pts

   GPT —Claude #4Gemini #3Grok #5

   Global edge deployment for fast responses, aggressive response caching, and direct integration with Cloudflare Workers.
