Gatling

Gatling is a load testing and performance engineering platform. Tests are written as code using SDKs for Java, Scala, Kotlin, JavaScript and TypeScript, which makes a load testing strategy versioned, reviewable and runnable inside a continuous integration pipeline. The hosted Enterprise Edition executes those tests across load generators and reports results in dashboards, with distributed tracing and a failure diagnosis feature that points at the root cause of a broken run. The AI layer is newer. An assistant named Aim helps assess testing maturity, plan a test strategy, set realistic service level objectives, choose a load injection shape and set up a testing campaign. An MCP server lets a coding agent drive Gatling Enterprise Edition directly, so tests can be created and run from the same place the application code is being written. The platform is aimed at performance engineers, site reliability engineers and development teams in organizations where capacity and latency carry real cost.
