Looks real nice! Unfortunately doesn't have graphs like "ali" or other popular load testing tools, and the cloud version is very expensive (starts at $74/month) if you just want some nice visualization of your results.
You can use it with influxdb and grafana which gives you 5seconds delay - almost real time I say.
k6 can be used together with Grafana[1] so you can get pretty charts for free :-)
As a lover of Grafana, I love this! Thanks, didn't know. I'll definitely give k6 a try!
I tried the cloud version of this out on someone's recommendation last week, and was impressed. It gets expensive quite fast looking at the price plans though. The k6 open source library behind it seems cool too.
