What people search for in this segment
Searchers often want gateways, routing, testing, BYOK support, deployment, and compatibility layers, not necessarily generic agents. This category needs to speak directly to developer and platform intent.
How to compare infrastructure products
Prioritize protocol compatibility, model coverage, logs, monitoring, fallback behavior, and operational cost control. Teams care more about reliability and operability than feature sprawl.
