If you want to manage multiple AI vendors through one gateway, you generally want an AI gateway / model gateway / LLM proxy.
Good options
- OpenAI-compatible gateways/proxies
- LiteLLM
- Portkey
- Helicone (more observability-focused, can also help route traffic)
- Cloud/vendor-neutral API gateways
- Kong
- Envoy
- Apigee
- Tyk
- with AI-specific routing/plugins layered on top
What to look for
A good multi-vendor AI gateway should support:
- Unified API across vendors/models
- Routing and fallback between providers
- Load balancing and traffic splitting
- Retries, timeouts, rate limiting
- Cost tracking
- Logging/observability
- Key management and secrets isolation
- Policy controls for compliance and data filtering
Practical recommendation
If your main goal is one developer-friendly gateway for OpenAI, Anthropic, Gemini, Azure OpenAI, etc., start with LiteLLM or Portkey.
-
Choose LiteLLM if you want:
- open-source
- lots of provider support
- flexible routing/fallback
- easy self-hosting
-
Choose Portkey if you want:
- a more managed product
- strong observability and control features
- simpler team operations
If you want, I can also recommend the best choice for your stack (self-hosted vs managed, startup vs enterprise, OpenAI-compatible vs not).
