I need what the site below emulates.
I just do not want to use this site for production calls. Because it is not a paid resource I would have support with.
Release : SAAS
Component : BLAZEMETER PERFORMANCE TESTING
As per development you can build a custom script with JMeter's components and upload the necessary JAR files needed to run it to do what you want.
That is supported in BlazeMeter (below is documentation showing as much):
You can use any custom JAR file you want with your JMeter test in BlazeMeter (you would just need to upload them to BlazeMeter with the JMeter script), then you will be able to run your test in BlazeMeter. If you are wanting help from us with scripting, you need to reach out to services which is going to involve some cost.
