Swagger Data Saver is a Chrome extension designed to enhance the Swagger UI experience for API development. This free tool introduces advanced features such as smart data persistence, which remembers user inputs in request fields, making them reusable with a simple click. The interface remains clean and non-invasive, featuring a subtle lightbulb icon that indicates saved suggestions, ensuring that users can focus on their API testing without unnecessary distractions.

Key functionalities include smart suggestions for recent values based on method/path/parameter, the ability to favorite important entries, and a safe clear option to remove unpinned data. The extension operates entirely on local storage, guaranteeing user privacy with no tracking or cloud storage involved. Compatible with Chrome and Chromium-based browsers, Swagger Data Saver streamlines the API testing process, making it a valuable tool for developers.
