A PWA (Progressive Web App) is like a website that acts like a mobile app—but you don’t have to download it from the app store. It gives you the best of both worlds: the convenience of a website and the features of an app. You can use it offline, it loads super fast, and you can even add it to your phone’s home screen without taking up much space. PWAs make using a site feel smoother and more app-like, even if your internet is slow. Plus, they can send push notifications, which is great for businesses that want to stay in touch with their users.
