What StresStimulus is
StresStimulus is Windows load-testing software for websites, mobile apps, and enterprise applications. It measures performance and scalability under heavy traffic through a wizard for recording, configuration, and execution, while its graphical interface can create test cases without scripting. Supported protocols include HTTP, HTTPS, AJAX, SOAP, WCF, binary WCF, and XML over HTTP. CSV data, browser and network mixes, think times, cache settings, and session behavior help shape workloads. During runs, the software graphs requests per second, response time, bandwidth, and errors, with reports covering pages, requests, and virtual users. Tests can run on one machine or use load generators on-premises, in private clouds, or in AWS and Azure. The free edition supports 250 virtual users and one-hour tests. An extendable seven-day trial supports up to 10,000 virtual users with full support.
