Freshin is a Chrome extension that enhances web development by automating the process of refreshing browser tabs. Ideal for developers using Visual Studio Code (VS Code), it listens for file changes in a specified directory and triggers an instant refresh in the browser. This feature eliminates the need for manual page reloads, allowing developers to see updates in real-time, which greatly improves workflow efficiency.

Key functionalities include auto-refresh on file change, where any saved file in VS Code causes the relevant browser tabs to refresh. Users can also specify keywords to target specific tabs, ensuring only those with the designated keyword in their URL are refreshed. The integration with the Freshin VS Code extension ensures a seamless experience, making it easy to set up and use for a streamlined development process.
