WAPT User Interface

We help businesses eliminate the risks of unexpected performance faults in their web solutions. Our load testing tools and services are targeted at all types of websites from online stores to corporate ERP and CRM systems.

With help of our WAPT solution you can design load tests and make thousands of virtual users execute concurrent sessions against your web application in a matter of minutes. Session-specific parameters and variables are defined with help of a convenient user interface that lets you browse and modify your test as a plain sequence of HTTP requests. This way you can emulate even the rich client functionality in the data-driven mode without any script programming.

Descriptive graphs and reports will show the performance of your system components under various load conditions, isolate and fix any bottlenecks and optimize your software and hardware configuration.

If you are about to release a new version of your web application, WAPT will help you answer several questions that may be crucial for the success of your business:

How many users the website can handle concurrently?
How fast your application will respond to the user actions?
How often users will get errors and need to reconnect?
Will your website respond correctly to a stress load?
Can it get back to normal operation after peak hours?

For customers requiring high capacity load tests and fine tuning of complex test scenarios we offer the Pro version of our product. In addition to the regular WAPT features it provides distributed cloud-ready testing solution, online server and database monitoring, ability to implement session values calculation with JavaScript code, custom pass/fail criteria and integration capabilities.

What testing specialists say:

Not your father's testing tool: As a matter of fact, WAPT takes user simulation to a higher level.

- Edmond Woychowsky, CNET Networks

We've been using WAPT and have been quite pleased with the result. Great tool for benchmarking/replay. I have to admit the tool is rock-solid, incredibly performant itself, and delivers dependable, repeatable data.

- John Overbaugh , QA professional

This software has proven invaluable as a means of being able to simulate virtual user load on the new web servers located in our new Data Centre. We are currently in the process of migrating over, and this solution was key for testing how much load our new DC could take in its current setup.
