Gatling Studio is a desktop application designed to seamlessly transform actual user interactions from web browsers into effective load tests that are executable, leveraging the powerful Gatling engine in a Java/Maven project format within a matter of minutes. It allows users to capture a live browsing session or import a previously recorded HAR file, automatically filtering out unnecessary elements like static files, advertisements, and external trackers, while also enabling customization of the user-flow by domain or request type. This process results in the generation of production-ready Gatling code which can be managed through version control and further developed as needed. Users can then open the generated project in an Integrated Development Environment (IDE), commit it to source control, and tailor it with injection profiles or parameterization, facilitating local execution with Gatling Community Edition or scaling up through Gatling Enterprise Edition. The application is compatible with Windows, macOS, and Linux, and integrates well with Chromium-based browsers, making it ideal for performance engineers, QA teams, and developers who want to streamline test creation while adhering to comprehensive “test-as-code” methodologies. With its user-friendly interface and robust functionality, Gatling Studio significantly enhances the efficiency of load testing processes.
