RolesTab is a desktop browser built specifically for developers, QA engineers, and AI-powered development workflows.Every tab has its own isolated cookies, local storage, IndexedDB, cache, and authentication state. This makes it possible to log into multiple accounts simultaneously within the same window and test complex role-based applications with ease.Beyond manual testing, RolesTab lays the foundation for AI-assisted browser automation by providing isolated environments where AI agents can safely execute and validate end-to-end user workflows.
