What is React Developer Tools?
React Developer Tools is a Firefox extension that gives developers the ability to inspect the React tree within their webpages, including aspects such as the component hierarchy, props, state, and more. The tool respects user privacy as it requires permissions to access the page's React tree, yet it transmits no data remotely. It is also fully open-source, with its code base available for perusal and contribution.
