The models' case: Achieves industry-leading raw throughput and sub-millisecond response times by building on fasthttp rather than standard net/http, leveraging zero-allocation buffer. The models' main caveat: Not for teams requiring standard net/http handler compatibility. The strongest alternative is Gin — Best overall balance of top-tier zero-allocation routing, mature production behavior, broad middleware support, and net/http compatibility. Not unanimous: ChatGPT picks Gin; Claude picks net/http.
