Ranger focuses on end-to-end QA testing for web-based products by combining AI and human expertise. An AI agent writes tests, which are then reviewed by a team of human QA experts to ensure quality. This dual approach helps catch real bugs and keeps core workflows intact, so development teams can move faster on their product roadmaps. Ranger targets teams that want rapid development and deployment, offering a service that automates and refines testing tasks. On average, its clients save about 200 hours per engineer each year. The company's goal is to make QA more efficient and trustworthy, pulling testing work away from developers so they can focus on building features.
