Cloud-hosted tool for performance testing web services on demand

Performance testing is very important, so you should do it in the most insightful way possible. Simulate both real users' actions and real-life conditions when you end-to-end performance test a web application. If your web service fails to do the job for your customers, the cost of such issues can be tens of thousands of dollars. Imagine you can find all issues and system limitations, fix them and release a perfectly working web service. That is exactly what Loadero helps to achieve.
