Web Apps (PWA)
Progressive Web Apps – Native-Grade Offline Power & Zero App Store Friction – Fast, durable, and transparently calculated at 140 €/h package rate.
App Store monopolies throttle your growth, steal 30% of your revenue, and gatekeep your deployments. Progressive Web Apps (PWAs) deliver native application experiences directly via the browser—securing 100% of your profits through an unrestricted Mobile Conversion Engine. We systematically eliminate technical debt and optimize end-to-end data pipelines for sub-second rendering, superior conversion rates, and 100% data sovereignty. Engineered bespoke for ambitious B2B enterprises, SaaS builders, and mid-market leaders to drive verifiable enterprise value without vendor lock-in.
Do you want app-like engagement without app store fees?
PWAs deliver native app experiences directly through the browser. We engineer offline-capable, highly interactive web applications that drive retention.
You are wasting capital developing multiple native apps that nobody wants to download.
The traditional app model is broken for B2B. Forcing your enterprise clients to navigate an App Store creates massive friction. You pay an agency €150k for an iOS and Android codebase, face constant approval delays, surrender 30% of your margins to Apple, and end up with terrible installation rates.

Enterprise Web Architecture Checklist
Audit your current infrastructure before commissioning a major platform overhaul:
- Does your initial mobile JS bundle stay below 100 kB?
- Are assets automatically served in modern AVIF/WebP formats with static dimensions?
- Are your critical APIs protected by Zero-Trust hardware tokens and strict rate limiting?
- Does your application execute on a serverless Edge runtime with global caching?
- Do all interactive elements pass WCAG 2.1 AA contrast and screen-reader standards?
- Can your platform operate 100% tracking-free without requiring an annoying cookie banner?

Outdated Agency Standard vs. MyQuests Engineering
The Service Worker Bypass
We implement advanced Service Workers—background scripts that intercept network requests. If your team loses 5G connection in a warehouse, the PWA doesn't crash; it reads off the local cache, allows data manipulation, and precisely syncs back to the server the millisecond the connection is restored.
„Developing a native app as a first step can often introduce unnecessary overhead. A Progressive Web App (PWA) delivers comparable push-notification capabilities and home-screen presence, but with minimal installation friction and a unified, cost-effective codebase.“
Apple iOS does not support PWAs or web push notifications reliably.
Since iOS 16.4, Apple natively supports Web Push Notifications, badge counts, and full-screen Home Screen installation. PWAs match native app capabilities for 95% of business use cases without app store tax.
FAQ
What is the primary commercial advantage of a PWA over a native iOS/Android app?
PWAs run directly in the browser across all devices with zero 30% App Store fees, zero app store review delays, and instant frictionless Home Screen installation via single URLs.
What does it cost to engineer an enterprise B2B Progressive Web App?
PWA development starts at 3,920 € (Tier I: 28h) for core caching and installation setups, and ranges to 7,700 € – 13,300 € (Tiers II & III) for full offline sync and barcode scanner engines.
How does offline mode function in a Progressive Web App?
Service Workers intercept network requests to serve cached assets while client data persists in local IndexedDB storage. Changes automatically queue and sync once connectivity is restored.
Can PWAs access mobile hardware features like cameras, GPS, and barcode scanners?
Yes. Modern Web APIs allow PWAs to access cameras, GPS geolocation, barcode/QR scanners, device orientation sensors, and local file storage with standard user permissions.
How do customers or employees install a PWA without an app store?
Users tap 'Add to Home Screen' via standard browser prompts. The PWA installs instantly without multi-hundred megabyte downloads, launching full-screen without browser address bars.
Do PWAs support Web Push Notifications across both desktop and mobile devices?
Yes. PWAs support native Web Push Notifications across Android, Windows, macOS, and iOS (since iOS 16.4), allowing automated re-engagement even when the app is closed.
What is the difference between a PWA and hybrid frameworks like React Native or Flutter?
Hybrid frameworks require separate compilation and app store approvals. PWAs maintain a single unified TypeScript codebase accessible instantly via standard web URLs.
How much development and maintenance cost does a PWA save compared to native apps?
A PWA eliminates maintaining separate iOS (Swift) and Android (Kotlin) codebases, cutting initial engineering costs and ongoing maintenance budgets by 50% to 70%.
Are PWAs suitable for industrial field service, logistics, and warehouse workflows?
PWAs are ideal for field operations. Technicians record inspections, scan inventory barcodes, and capture signatures offline in remote basements without network dropouts.
How secure is data stored within a B2B Progressive Web App?
Data is encrypted in IndexedDB using Web Cryptography APIs, secured behind biometric WebAuthn logins, and transmitted exclusively over TLS 1.3 encrypted connections.
Why do you exclusively build with Next.js, React, and Astro instead of WordPress or Typo3?
We rely uncompromisingly on modern frontend architectures. Legacy PHP monoliths introduce security vulnerabilities and slow rendering. With Next.js 15, React 19, and Astro, we deliver sub-second performance, maximum scalability, and 100% long-term investment protection.
Why do you charge 140 €/h for packages instead of the regular hourly rate of 200 €/h?
Our regular rate of 200 €/h applies to spontaneous ad-hoc consulting. Contracted packages allow us to plan engineering capacity efficiently. We pass this 30% planning advantage directly to our clients.
Do we own 100% of the intellectual property, code, and deliverables upon project completion?
Yes, completely. Upon full payment, you receive 100% full ownership of all source code, Git repositories, design files, campaign accounts, and data. There are zero licensing dependencies or vendor lock-ins.
How does day-to-day collaboration work in practice?
We operate 100% remote, digital, and async-first via GitHub, Linear, Notion, and Loom. Touchpoints are focused into compact, outcome-driven sprint reviews, eliminating costly travel and meeting overhead.
Do you provide ongoing support and SLAs after launch?
Yes. Through our transparent SLA packages starting at 350 € / month, we provide continuous uptime monitoring, encrypted security backups, Web Application Firewall (WAF) tuning, and core framework updates.
