Trusted and top rated tech team

Cross-platform app development without native codebases

Native apps require separate iOS and Android teams that slow releases. PWAs use service workers and web APIs to deliver installable applications with offline capability and push notifications from a single codebase. We work with CTOs where maintaining multiple native apps hinders velocity but web-only solutions lack device capabilities.

Our capabilities include:

Service worker implementation
Offline-first architecture
Web app manifest configuration
Push notification integration
App store distribution strategy
Native app to PWA migration

Who we support

We work with organizations where maintaining separate native apps creates bottlenecks and PWAs can deliver app-like functionality across platforms without platform-specific development teams.

SaaS Companies Reducing Overhead

You maintain iOS and Android apps with separate teams coordinating feature releases. Platform-specific bugs delay launches, and hiring specialists for each platform is expensive while web developers are more available.

E-Commerce Platforms Improving Reach

Your mobile web traffic converts poorly compared to apps but app store friction limits downloads. Users abandon during app installation, and search engines can't index native app content or product pages.

Media Companies Scaling Content Delivery

You publish content that needs instant updates across devices without app store approval delays. Native app maintenance consumes resources while most users access content through browsers anyway.

Ways to engage

We offer a wide range of engagement models to meet our clients’ needs. From hourly consultation to fully managed solutions, our engagement models are designed to be flexible and customizable.

Staff Augmentation

Get access to on-demand product and engineering team talent that gives your company the flexibility to scale up and down as business needs ebb and flow.

Retainer Services

Retainers are perfect for companies that have a fully built product in maintenance mode. We'll give you peace of mind by keeping your software running, secure, and up to date.

Project Engagement

Project-based contracts that can range from small-scale audit and strategy sessions to more intricate replatforming or build from scratch initiatives.

We'll spec out a custom engagement model for you

Why choose Curotec for PWA development?

PWA adoption often fails due to misunderstood service worker complexity or ignored iOS limitations. Our engineers know which features work reliably across platforms, when to opt for app store distribution, and how to build offline-first without sync conflicts. This ensures a realistic PWA implementation that accounts for platform constraints, preventing unwelcome surprises post-launch.

FAQs about our PWA development

How do PWAs compare to native apps?

PWAs offer single codebase deployment and instant access through browsers without app store approval. Native apps provide better performance for graphics-intensive tasks and fuller device API access. Most content and commerce applications work well as PWAs.

What are the iOS limitations for PWAs?

iOS historically limited PWA capabilities but iOS 17 improved push notifications and installation. Limitations remain around background processing and some device APIs. We design fallbacks for iOS-specific gaps while leveraging full capabilities on Android and desktop.

Can PWAs be distributed through app stores?

Yes, PWAs can be packaged for Google Play Store and Microsoft Store, combining app store discoverability with single codebase benefits. This hybrid approach reaches users who prefer app stores while maintaining web deployment flexibility.

How do you handle offline functionality?

We implement service workers with caching strategies for application shells, assets, and API responses. Offline-first architecture queues user actions locally and syncs automatically when connectivity returns, preventing data loss during network interruptions.

How quickly can your engineers start contributing?

Our PWA engineers typically begin implementation within the first week. They’re familiar with service worker patterns, manifest configuration, and offline-first architecture that match progressive web app standards.

What's involved in migrating from native apps to PWAs?

We assess device API requirements, identify features needing fallbacks, and implement progressive migration. Critical functionality moves first while testing cross-platform behavior. Most teams run PWA and native apps in parallel initially before full transition.
