EnvVars is a free Chrome add-on designed for developers working with various frontend frameworks. It allows users to view and debug environment variables seamlessly from applications built with React, Vite, Next.js, Vue, Nuxt, and more. With features like multi-framework detection and smart parsing, it simplifies the process of accessing configuration details in bundled or minified code. The interface is user-friendly, requiring no setup, and offers one-click access to scan the current web page for environment variables.

Key functionalities include search and filter capabilities for locating specific variables, along with options to copy or export variables as JSON. EnvVars prioritizes user privacy by processing data locally in the browser without any external communication. This open-source tool not only aids in debugging API URLs and verifying environment deployments but also ensures that developers can maintain security by auditing exposed variables.
