Ranger is a software testing platform designed to enhance quality assurance (QA) processes for engineering, product, and design teams. The platform leverages advanced AI technologies, including large language models, to generate efficient end-to-end tests automatically, identify and resolve flaky tests, and provide improved failure insights. With a mission to empower ambitious teams to focus on development rather than testing, Ranger collaborates with fast-growing companies such as Clay, Suno, and Dust, as well as notable partners like OpenAI. By streamlining the testing and QA process, Ranger aims to enable teams to deliver high-quality software at a faster pace while minimizing downtime associated with bug fixing and test maintenance.
