A new contender has entered the crowded field of Go HTTP routers. MuxMaster, released as v1.1.0 under the MIT license, is a radix-tree router built on the Go standard library alone — no external dependencies, no custom handler types, and, according to its published benchmarks, faster than every alternative currently available to Go developers. The module is hosted on GitHub at github.com/FlavioCFOliveira/MuxMaster , with documentation, an API reference, and reproducible benchmarks at muxmaster.net . What it is At its core, MuxMaster is a drop-in replacement for http.ServeMux . Routes are matched through a radix tree with O(k) lookup complexity, where k is the length of the request path rather than the number of registered routes. The router preserves the net/http handler interface exactly: handlers remain http.Handler , middleware remains func(http.Handler) http.Handler , and existing code compiles without modification.…
