Progressive Web Apps (PWAs) are web applications that have responsive designs, work offline, and can be installed on a user's home screen. Key features of PWAs include being responsive across devices, working offline through service workers, being discoverable through web app manifests, automatically updating, using secure HTTPS connections, and allowing users to re-engage through push notifications and installing on home screens without an app store. PWAs provide faster experiences for web users compared to regular websites and allow developers to engage users similar to native mobile apps.
