Gatling is a load- and performance-testing framework based on Scala and Netty. The first stable release was published on January 13, 2012. In 2015, Gatling's founder, Stéphane Landelle, created a company (named "Gatling Corp"), dedicated to the development of the open-source project. According to Gatling Corp's official website, Gatling was downloaded more than 20,000,000 times (2024). In June 2016, Gatling officially presented Gatling Enterprise the commercial version which included test orchestration and team collaboration features.

The software is designed to be used as a load testing tool for analyzing and measuring the performance of a variety of services, with a focus on web applications, application programming interfaces (APIs), and microservices.

Gatling was mentioned twice in ThoughtWorks Technology Radar, in 2013 and 2014, "as a tool worth trying", with an emphasis on "the interesting premise of treating your performance tests as production code".

The latest minor release is Gatling 3.14, published on May 12, 2025.
