Ripplet is a powerful,high available,flexible,collaborative load/stress test tool. It aims at providing an environment where users are able to do the tasks as follows :

* illustrate test design and outline load description clearly
* control realistic performance load efficiently, both on logic and data flow
* diagnose performance spikes and bottlenecks easily
* evaluate system capacity quickly and correctly
* share achievements for developers or customers, not only reports but test plan for product enviroment stage evaluation

Use it, extend it, just making your load test fruitful, your production stable. Hopefully, it's pretty much everything you seek in load test and it's beyond your expectation.
