The perfect tool to load test your app.


While migrating ScrapingBee out of Heroku we wanted to know how the new infra would react to the load. Simulating 400 users can be very resource-intensive and it would have been difficult to do it on our own machine. In Loadster it took me literally less than a minute. Using Loadster also allowed us to perfectly size our servers and we now know perfectly what are our bottlenecks what we will need to upgrade once we hit a certain usage threshold.


One killer feature would be to compare multiple testing runs. Let's say I launch test A. Then tweak my app and launch test B, I'd love to be able to easily compare A and B regarding what I changed in the app.
