Progressive web apps,
installable and offline

A progressive web app development company designs and builds installable, app-like web experiences using service workers and a web app manifest, creating apps that work offline, send push notifications, and install to the home screen without going through an app store. Beyond building the PWA, that means performance and Lighthouse work, an offline and sync strategy, and ongoing maintenance. At Idealogic it is senior engineers who have shipped production PWAs, not a junior team learning on your budget.

PWA cost is driven by scope, including features, integrations, and how much offline and backend work the app needs, not by a fixed price. A PWA is often the most economical route to an installable app because one codebase serves the web and the install, so there is no second native build. We scope it precisely before any commitment, and our full breakdown lives in the mobile app development cost guide.

A progressive web app is a website built to behave like an installed app: it loads fast, works offline, sends push notifications, and installs to the home screen, all from one web codebase. Choose a PWA when reach, low cost, and instant updates matter more than app-store presence or the deepest native features. When you do need the store or native depth, we cover that trade-off in our native vs cross-platform guide.

Yes. We turn existing websites into installable PWAs by adding a service worker for offline and caching, a web app manifest for install, and push where it helps, then tuning performance so it feels like an app rather than a page. We start with an audit of the current site and ship the PWA layer incrementally rather than rebuilding from scratch.

Yes. A service worker caches the app shell and data so a PWA keeps working with no connection and syncs when it returns, and the web push API delivers notifications on supported platforms. These are core to a good PWA, not extras; we design the offline and sync strategy up front, since retrofitting it later is the expensive path.

Usually, yes. A PWA is one web codebase that serves the browser and the install, so there is no separate iOS and Android build to fund and maintain, and updates ship instantly without app-store review. The trade-off is less access to native depth and no app-store storefront, which is the exact native-versus-PWA call we help you make for your product.

Mostly React and Next.js, with Vue or a vanilla service-worker setup when that fits the job better. For commerce we build on Magento PWA Studio and headless stacks. The framework follows the product, not the other way around, so we pick it during scoping instead of forcing every PWA through one toolchain.

Yes, and that's one of their quiet advantages. A PWA is still a website, so it gets crawled and indexed like any page, unlike a native app search engines can't see inside. The service worker also makes it fast, and speed feeds Core Web Vitals. We add the install and offline layer without breaking server rendering, so the SEO you'd get from a normal site stays intact.
