Can a PWA work offline?

Yes. Selected content and workflows can remain available using service workers, Cache Storage and IndexedDB.

Can users submit forms while offline?

Yes. Supported actions can be stored locally, queued and synchronized after connectivity returns.

How do you prevent stale data?

We define freshness policies, versioning, timestamps, cache invalidation and visible synchronization states.

What happens when two users change the same record?

Conflict rules can compare versions, timestamps or business priorities and then merge, reject or request review.

Can media be available offline?

Yes, selected images, documents or other assets can be cached when storage limits and product requirements allow.

How are failed synchronizations handled?

The application can retry safely, show pending or failed states and provide recovery actions to the user.

Can users install a PWA?

Supported browsers allow users to add a PWA to a home screen or desktop without a traditional app-store installation.

Can a PWA send push notifications?

Yes, where supported by the browser and operating system and after the user grants permission.

Does a PWA need an app store?

No. It can be accessed directly through a URL, while selected packaging approaches can also support some stores.

Can the install prompt be customized?

The browser controls the native prompt, but a branded educational prompt can be shown at the right moment before triggering it.

Can a PWA have its own icon and splash screen?

Yes. The manifest defines icons, colours, display mode and other installation presentation settings.

Can we track installations and notification engagement?

Yes. Analytics events can measure install prompts, accepted installations, notification permissions, opens and downstream actions.

Can a PWA improve Core Web Vitals?

Yes. Better caching, code splitting, responsive media and frontend delivery can improve loading, responsiveness and stability.

Do PWAs work in every browser?

Core web functionality works broadly, while advanced capabilities vary. We design progressive enhancement and graceful fallbacks.

How do service-worker updates work?

An update strategy controls when new service-worker code and cached assets are downloaded, activated and shown to users.

Can a PWA be SEO-friendly?

Yes. Search-friendly routing, metadata, rendering, structured data and crawlable content can be included in the architecture.

How do you test weak-network performance?

We test throttled connections, offline states, repeat visits, cache behaviour, interaction latency and recovery scenarios.

Can a PWA support high traffic?

Yes. Scalability depends on frontend architecture, APIs, caching, CDN configuration, database capacity and infrastructure.

Can you convert an existing website into a PWA?

Yes. We can assess the current architecture and add appropriate PWA capabilities where technically suitable.

Can you modernize an existing PWA?

Yes. We can improve caching, browser compatibility, service-worker updates, performance, notifications and architecture.

What affects the cost of PWA development?

Cost depends on design, features, offline complexity, integrations, backend work, security, testing and migration requirements.

Do you provide support after launch?

Yes. Support can cover performance, caching, compatibility, analytics, security updates and feature enhancements.

Who owns the PWA source code?

You retain ownership of approved custom code and project deliverables according to the agreed engagement terms.

Can you work with our internal development team?

Yes. We can provide complete delivery, a dedicated team or focused architecture and engineering support.

What is a Progressive Web App?

A Progressive Web App is a web application enhanced with capabilities such as installation, offline access, fast repeat loading and supported push notifications.

How is a PWA different from a normal website?

A PWA uses service workers, a web app manifest, local storage and browser APIs to deliver more reliable and app-like behaviour.

When should a business choose a PWA?

A PWA is valuable when reach, mobile performance, weak-network support and lower installation friction are important.

How long does PWA development take?

Timing depends on product complexity, offline workflows, integrations, design scope and whether an existing system is being converted.

Can a PWA replace a native mobile app?

For many content, commerce and operational products it can. Hardware-heavy or platform-specific products may still need native development.

Can you audit our current website for PWA readiness?

Yes. We can review architecture, performance, HTTPS, browser compatibility, caching opportunities and conversion effort.
