Cool, I didn't see this tool before. I have tried most open source load testing tools out there, as part of writing a couple of review articles on them (https://grafana.com/blog/2020/03/03/open-source-load-testing...) and my gut reaction is this one looks like a Golang alternative to Wrk (https://github.com/wg/wrk) in that its main feature is speed. I'd bet Wrk still blows it out of the water though - in my testing, no other tool got anywhere close to Wrk's level of performance. Still, if you need scale and want to hammer a single URL with a very large number of requests/second and prefer a Go application (Wrk is written in C) it may be a good alternative.
