Load Tester

Load Tester is a performance and load testing software used to simulate user traffic against web and mobile applications to identify bottlenecks. It helps test application stability under various realistic load conditions.

What is Load Tester?

Load Tester is a popular performance and load testing software used by developers and testers to determine if web and mobile applications can handle expected user traffic. It simulates hundreds or thousands of concurrent virtual users accessing an application to identify performance bottlenecks under load before the app goes into production.

Key features include the ability to:

  • Simulate different user behaviors like viewing products, adding items to a cart, logging in, etc.
  • Ramp up load using advanced scheduling options to increase traffic
  • Identify application bottlenecks down to the server and code level
  • Test APIs and measure response times
  • Integrate with CI/CD workflows for automation
  • Produce detailed analytics reports to share with stakeholders
  • Emulate global traffic originating from different geographic regions

Using Load Tester, development and QA teams can validate that web and mobile applications meet expected response time SLAs and ensure a smooth user experience even during traffic spikes. This prevents slow load times, errors, or crashes when an app transitions from staging to production. Teams can iteratively improve application stability and performance before launch.
