Appium was created by Dan Cuellar in 2011 and later maintained by the open-source community under the JS Foundation. The initial vision was to provide a cross-platform, open-source automation tool for mobile apps that didn’t require modifying app code. Cuellar aimed to bring the simplicity of Selenium testing into the mobile ecosystem. The result was a tool that supports multiple programming languages, platforms, and automation strategies. Today, Appium continues to evolve with contributions from global developers, including teams in New York, USA, who rely on it for testing high-performing mobile applications efficiently across devices.
