Offline functionality
Service worker caching set up so key parts of the app still work without a connection, not just a generic offline page.
Overview
An app-like experience without the app-store process
A progressive web app is a website built to behave like an installed app: it can work offline, be added to a home screen, and send push notifications, without going through app store review or requiring a separate native codebase. It's not a replacement for a native app in every case, but for a lot of products it covers what users actually need.
We build the underlying frontend to the same standard as any other project, then add the PWA layer on top: a service worker for offline caching, a web app manifest for installability, and performance tuning aimed at PWA-specific targets rather than just general page speed.
Tools & platforms we use
- Workbox
- Web App Manifest
- Lighthouse
What's included
Offline support and installability, built properly
Installable app setup
A proper web app manifest so users can add it to their home screen and it opens like an installed app.
Push notifications
Wired up where the product actually needs them, not added just because the platform supports it.
PWA-specific performance tuning
Optimized against the specific targets that make a PWA feel like an app rather than a slow website.
Questions
Common questions about progressive web apps
4 questions
What's the actual difference between a PWA and a native app?
A PWA is still a website under the hood, installed to a home screen and capable of offline use and notifications, but without app store distribution or access to every native device API. A native app has deeper device access and typically better performance for graphics-heavy use cases, at the cost of app store review and separate iOS and Android codebases.
Can users install it without going through an app store?
Yes, that's one of the main appeals. Users add it to their home screen directly from the browser, no app store listing or review process required.
Does a PWA work well on iOS?
Reasonably, though Apple has historically supported fewer PWA features on iOS than Android does, particularly around notifications. We'll tell you upfront if a feature you want isn't reliably supported on iOS Safari.
When should we build a PWA instead of a native app?
When the features you need (offline access, installability, notifications) fit within what a PWA supports, and you'd rather maintain one codebase than separate iOS and Android apps. If you need deep native device integration, a native or React Native app is usually the better fit.
