Progressive web apps (PWAs) in 2025: The smart alternative to native apps

Progressive Web Apps represent the most significant shift in mobile strategy since responsive design. By delivering native app experiences through web browsers, PWAs eliminate app store friction, reduce development costs by 70%, and reach users instantly. This guide provides everything you need to decide if a PWA is right for your business, backed by real implementation data and success metrics from 2025.

What PWAs Really Are (And Why They Matter Now)

Progressive Web Apps aren’t just websites pretending to be apps—they’re a fundamental reimagining of how we deliver digital experiences. PWAs combine the reach of the web with the engagement of native apps, offering capabilities that seemed impossible just years ago.

The PWA Revolution in Numbers

Current adoption and impact statistics paint a compelling picture:

• Twitter Lite (PWA) increased pages per session by 65% and tweets by 75%
• Pinterest saw 40% more time spent and 44% increase in ad revenue
• Alibaba achieved 76% higher conversions across browsers
• Starbucks PWA is 99.84% smaller than their iOS app

By 2025, PWAs have matured from experimental technology to proven business solution, with major brands replacing or supplementing native apps with progressive web experiences.

PWA Capabilities That Change Everything

Works Offline Like Magic

Unlike traditional websites, PWAs function without internet connectivity:

• Service workers cache critical resources
• Background sync uploads data when connection returns
• Offline forms save entries until connected
• Local storage maintains user state

Real-world impact: E-commerce PWAs show 20% fewer cart abandonments due to connection issues.

Installs Without App Stores

Users add PWAs to their home screen directly from browsers:

• No app store approval process or delays
• No commission fees (saving 15-30% on transactions)
• Instant updates without user action
• Smaller size (typically 1-10MB vs 30-150MB for native apps)

Business benefit: 3x higher installation rates compared to native app store downloads.

Sends Push Notifications

Engage users like native apps:

• Re-engagement rates 4x higher than email
• Segmented messaging based on user behavior
• Time-zone aware delivery
• Rich notifications with images and actions

Metric improvement: 50% increase in repeat visits when notifications enabled.

Accesses Device Features

Modern PWAs access extensive device capabilities:

• Camera and microphone for video calls and photo uploads
• Geolocation for location-based services
• Accelerometer for motion-based features
• Biometric authentication for secure access
• File system access for document handling
• Bluetooth and NFC for device connectivity
