wtf is devtools?

Vue DevTools is a debugging tool for developers who build web applications using Vue, a JavaScript framework for creating user interfaces. It lets developers inspect the internal state of a running Vue application, which is something a browser's built-in developer tools cannot do on their own. The tool is available in several forms. It can be installed as a browser extension for Chrome or Firefox, which adds a dedicated panel inside the browser's existing developer tools. It can also be added as a plugin directly into a Vite-based project, which means it appears as an overlay inside the application itself during development. A standalone desktop app version also exists for cases where the extension approach does not fit. The README for this repository is brief and mostly points to external documentation for setup details. It covers the four installation options and links to a contribution guide for anyone who wants to help improve the project. This is version 7 of Vue DevTools, which was previously called Vue DevTools Next during its development period. The older version 6 has been moved to a separate repository and is considered legacy. For a developer working with Vue, this tool makes it much easier to understand what a component is doing, track data changes, and find the source of unexpected behavior without adding console logs throughout the code.
