What is a Web App Manifest?
The Web App Manifest is a simple JSON file that tells the browser (and the operating system) how your web application should behave when installed on the user's desktop or mobile device. It dictates the app's name, icons, start URL, background color, and display mode (e.g., hiding the browser UI for a native feel). You can create it from scratch with our online manifest generator tool or use the full version of Progressier.
