Progressive Web Apps combine the best of web and mobile. They load fast, work offline, and can be installed on any device — without going through an app store. Could a PWA be the right solution for you?
A Progressive Web App (PWA) is a website that behaves like a native app. It can be installed on your home screen, works offline, sends push notifications, and loads almost instantly — all without being in the App Store or Play Store. For many businesses, PWAs offer the best of both worlds.
Twitter, Pinterest, Uber, and Starbucks all have PWAs. After Twitter launched its PWA, they saw a 65% increase in pages per session and a 75% increase in Tweets sent. Starbucks's PWA is 99.84% smaller than their iOS app — and works offline for menu browsing and order building.
PWAs are built on three core technologies: Service Workers (for offline and caching), Web App Manifest (for installability), and HTTPS (for security). Modern frameworks like React, Angular, and Vue all have excellent PWA support built in, which makes building one much simpler than it used to be.
Because a PWA is built once on standard web technology rather than separately for iOS and Android, development and ongoing maintenance costs are typically lower than building and maintaining two native apps. There's also no app store review process for updates — ship a fix and every user has it on their next visit. The tradeoff is limited access to some device-native features and, on iOS specifically, more restricted push notification and background capability than a true native app gets.
