LiteLLM - Pros & Cons
Pros
- ✓Open-source edition has no license charge for production self-hosting
- ✓One interface reduces application coupling to individual providers
- ✓Centralizes model and MCP access, cost controls, and logs
- ✓Supports private and air-gapped deployments
Cons
- ✗The customer must operate a critical production gateway
- ✗Enterprise pricing is custom and requires an annual agreement
- ✗Upstream model usage and infrastructure remain separate costs
- ✗Provider-specific behavior can leak through the normalized API
OpenRouter - Pros & Cons
Pros
- ✓One API key and one bill for hundreds of models across dozens of providers
- ✓Automatic fallback keeps apps running when a provider throttles or fails
- ✓OpenAI-compatible schema drops into most SDKs and agent frameworks unchanged
- ✓BYOK lets you keep your provider contracts/rate limits while using the gateway
- ✓Provider preference controls (price/latency/ZDR) give real routing flexibility
Cons
- ✗Extra network hop adds a small amount of latency versus calling providers directly
- ✗Single point of failure — an OpenRouter outage takes down every model at once
- ✗Free-tier models are rate-limited and rotate, so not suitable for production
- ✗BYOK still incurs a 5% fee after 1M requests/month, on top of provider billing
- ✗Enterprise controls (SSO, VPC peering, audit exports) are lighter than dedicated gateways like Portkey
