What is Gatling?

Gatling is an open-source tool for performance and load testing, particularly well-suited for testing web applications. It is built on Scala, Akka, and Netty, and allows you to write test scenarios using expressive SDKs in Scala, Java, Kotlin, JavaScript, or TypeScript. Gatling is designed to be high-performance and can simulate thousands of concurrent users with minimal system resources. It provides detailed reports and integrates well with CI/CD pipelines.
