Gatling

Gatling is a software tool used to test how well a website or online service can handle many users at once. It simulates multiple people accessing the site simultaneously to identify potential performance issues or bottlenecks. By doing this, developers can ensure their website remains fast and reliable under heavy load, improving user experience and avoiding crashes during peak times. Gatling provides detailed reports on response times, errors, and server performance, making it a valuable resource for optimizing web applications before they go live.
