What is a PWA?
A website that
behaves like an app.
A Progressive Web App is a single web codebase that installs to a phone home screen, runs offline, sends push notifications and feels native. No app stores, no submission fees, no waiting on App Review.
Updates ship the second you push to production — your users never have a "please update" friction. Same URL works on desktop, mobile, tablet.
Works offline
Service Workers cache the shell + last data. Tunnel? Plane? Still works.
Push notifications
Web Push on Android, Web Push on iOS 16.4+. Same code path.
One codebase, every platform
Desktop, iOS, Android, Windows, Linux. Same URL, same code.
Instant updates
No App Review, no 7-day rollouts. Push to prod, every device gets the new version on next open.
No store fees
Zero 30% Apple/Google take. You own the channel.
Honest comparison
PWA, Expo, native — when to pick what.
No religion, no "X is dead" takes. Each has a sweet spot. We'll tell you which one your project actually needs.

The fast-mobile stack
Why we ship to stores in four weeks.
A small, opinionated stack we've been refining since React Native 0.50.
Mobile UI
Expo + React Native
EAS Build & Submit handles signing, profiles and store delivery. OTA updates via EAS Update mean we patch live apps without re-submission.
Backend & APIs
Go & Rails 8
Go for high-throughput, low-latency endpoints (location, telemetry, payments). Rails 8 for everything else — auth, admin, billing, scheduled jobs.
PWA / Web
Service Workers + Workbox
Offline-first caching strategies, background sync for offline writes, Web Push for notifications. Ships as a single Rails 8 app.
CI / Distribution
EAS + GitHub Actions
TestFlight + Play Internal Testing builds on every PR merge. Beta to production toggle on-demand.
