What is QALIPSIS?

QALIPSIS is a specialized solution designed for performance and load testing, aimed at teams focused on the validation of distributed applications and services. By employing a Java-based domain-specific language, it enables developers, QA engineers, and DevOps teams to create testing scenarios, run tests with distributed load generators, and interpret results through a user-friendly web interface. The platform supports a variety of components, such as HTTP services, messaging systems, and databases, and provides plugins to execute workloads as well as integrations for test data export. Teams can choose to run QALIPSIS in a self-managed environment or utilize its cloud-based option, which streamlines the automation of tests within continuous integration and continuous deployment pipelines. Moreover, the platform features extensive reporting and monitoring tools, allowing teams to analyze critical metrics like response times, throughput, errors, and overall system performance when under load, which significantly bolsters their performance analysis and regression testing capabilities. By harnessing this valuable data, teams are empowered to make strategic decisions aimed at refining the efficiency and dependability of their software. Ultimately, QALIPSIS not only enhances testing processes but also contributes to delivering high-quality applications that meet user expectations.

What is Loadster?

Loadster helps engineering and SRE teams protect uptime and customer experience without standing up their own testing infrastructure. The platform combines on-demand load testing with continuous synthetic monitoring, so teams validate capacity before launches and catch problems in production between them. Load tests run from cloud regions and simulate users at any scale — from a few hundred to many thousands of concurrent virtual users. HTTP, real browser, and Playwright-based bots cover the range from API throughput checks to full end-to-end user journeys. Reports break down response times, error rates, page rendering metrics, and per-user playback, then save into a shared history that stakeholders can review together. The same scripts can be repurposed as 24/7 monitors that run continuously from multiple regions. Incidents flow through configurable notification policies to email, SMS, voice, or integrations like Slack and PagerDuty, and maintenance windows pause monitoring during planned work. Status pages give external audiences a clear view of service health. Loadster is consumption-priced through Loadster Fuel, with free units to evaluate the platform and no credit card required to sign up. Engineering, QA, and SRE teams use it to validate releases, catch regressions before users do, and respond faster when something breaks.
