Developers and QA testers often need to switch user-agents to test websites across different devices and browsers. A Chrome extension could allow users to create, save, and manage custom user-agent profiles, making testing more efficient. Developers and testers would pay for advanced features like profile sharing or syncing. Start with a basic extension offering custom profiles and expand with premium features. The biggest risk is competing with free alternatives.
