LiteLLM vs Bifrost: I Tested Both in Production. Here's What Actually Matters.

I spent two weeks running LiteLLM and Bifrost side by side. Same traffic, same models, same infra. I needed to pick one gateway for our team and I wanted real numbers, not marketing pages.

This is what I found.

The Setup

Both gateways sat behind the same load balancer. Traffic split 50/50. Backend was a mix of OpenAI, Anthropic, and Bedrock calls. Nothing synthetic. Real user-facing requests from our agent platform, roughly 200-400 RPS during business hours.

I tested on c5.xlarge instances (4 vCPUs, 8GB RAM). Not the t3.medium you see in most benchmarks. If you're choosing a production gateway, you should test on production hardware.
