StresStimulus is a load testing tool for websites, mobile and Enterprise apps. It determines the web performance and scalability of your application under the rigors of heavy traffic load. Hundreds or thousands of physical users are realistically emulated through on-premise load generators or in a cloud testing environment. At the same time, server monitoring information is collected in real-time to pinpoint application performance bottlenecks and isolate web speed issues. StresStimulus makes website stress testing and mobile performance testing super easy thanks to its end-to-end test wizard that walks you through recording, configuring and executing tests. It also saves time on mobile app load testing due to its out-of-the-box support for native app frameworks. What sets StresStimulus apart from other performance testing tools is its support for complex websites and apps combined with its competitive pricing.

The ReadyAPI platform accelerates functional, security, and load testing of RESTful, SOAP, GraphQL and other web services right inside your CI/CD pipeline. ReadyAPI allows teams to create, manage, and execute automated functional, security, and performance tests in one centralized interface - accelerating API quality for Agile and DevOps software teams. Teams can get started by importing API definitions like OAS (Swagger) or WSDLs, testing and recording live API traffic, or virtualizing web services to remove pipeline dependencies. Create comprehensive, data-driven functional API tests without the hassle of maintaining scripts. Generate load, stress, and spike tests to validate whether your API can handle real-world traffic conditions. Secure your vulnerable APIs from XSS, malformed XML, SQL injections and more with each deployment. Remove dependencies in your testing pipeline by virtualizing RESTful, SOAP, TCP, JMS, and other web services.

Loadster is a load testing platform for websites, web applications, and APIs. Your site has a breaking point. Loadster can find it before your users do! Create realistic test scripts and play them back with thousands of virtual users to find bottlenecks, improve performance, and prevent crashes. Record load test scripts right in your browser, with the Loadster Recorder extension for Chrome or Firefox. Just step through your site like a real user would while Loadster records every step into a script. After recording, play your script back in real time, and edit it if necessary. It's simple to add custom validation and capture server responses to reuse later in the script. Configure your test scenario with groups of bots in regions of your choosing, running your scripts, ramping the load up and down, to simulate the geographically distributed traffic you see in the real world.

IBM® Rational® Performance Tester helps software testing teams test earlier and more frequently as part of a DevOps approach. It validates the scalability of web and server applications, identifies the presence and cause of system performance bottlenecks and reduces load testing. Your software testing teams can quickly execute performance tests that analyze the impact of load on applications. Focuses the testing team on validating the scalability of applications rather than using a complicated test tool. Combines optimal access to underlying protocol data and remote system statistics with the ability to insert custom Java code. Builds on open standards and shared user experiences to integrate project team members. IBM Rational Performance Tester on Cloud enables large-scale and globally distributed performance testing. Rational Performance Tester generates performance and throughput reports in real-time, offering awareness of performance problems at any time during a test.
