Unfragile

httperf is named in the request but none of the candidate products' sources is httperf's own page, so no candidate can be confirmed as httperf itself. The closest matches in the sources are HTTP load and benchmarking tools: ghz 5 for gRPC load testing and httptap 9 for per-phase HTTP request timing, while hyper 3 and HTTPCore 8 are HTTP client libraries rather than load testers.

A question back: Do you want a tool to run httperf itself, or an alternative HTTP load-testing tool? Please confirm which platform or language you are working in.
