A PWA joins web and app: short load times, offline use, push notifications and installation on the home screen without a store. We bring existing React Native apps to the web with React Native Web.
With just one codebase you reach web browsers, mobile devices and desktop applications, without separate development processes for each platform.
Compared to native development for iOS, Android and web, a PWA drastically reduces development and maintenance effort, with a nearly identical user experience.
Progressive Web Apps run reliably on all modern browsers and operating systems, regardless of device type or manufacturer.
You talk to the people who build your app. No account manager in between, and no change of team between concept and operation.
From startup MVP to complex enterprise solution, we bring project experience
We have been working with React and modern web technologies since the early days, so we know all the pros and cons.

A PWA is a web application that behaves like a native app. It offers offline functionality, push notifications and can be installed on the home screen. PWAs are ideal for web apps that require app features without having to be published in app stores.
PWAs offer native app features such as offline functionality, push notifications, installation on the home screen and better performance. They load faster, work even without the internet and offer an app-like user experience.
Yes. With React Native Web your existing app also runs in the browser, from the same codebase. That saves development time and keeps the experience consistent.
Almost all app types can be developed as a PWA: E-commerce apps, business apps, social media apps, gaming apps, educational apps and more. Only apps with very specific native features require native development.
The development time depends on the complexity: an MVP takes 3-6 weeks, a complete PWA 2-4 months, complex applications 4-8 months. PWAs are often faster to develop than native apps.
We rely on modern web technologies: React, TypeScript, Tailwind CSS, Bun Runtime, React Query, React Router, Shadcn/ui, Zod, Conform and Framer Motion. Our stack is optimized for performance and maintainability.
We implement comprehensive testing: unit tests with Jest, integration tests, E2E tests with Playwright, PWA-specific tests (service worker, offline functionality) and manual tests on various devices.
PWAs don't have to be published in app stores, that's one of their advantages. They can be installed directly via the browser. For additional reach, however, they can also be published in app stores.
We offer comprehensive maintenance and support: regular updates, performance optimizations, new features, security updates and PWA-specific improvements. Our team remains your point of contact even after the launch.
We offer direct support from our development team. We respond to technical problems within 24 hours and to critical issues immediately. You have a dedicated contact person and can contact us at any time.
The costs depend on the complexity: simple PWAs cost €10,000-25,000, medium PWAs €25,000-50,000, complex PWAs €50,000-120,000. PWAs are often cheaper than native apps. Use our free app cost calculator for a precise estimate.
Yes. An MVP shows within three to six weeks whether your idea holds up: a working version with the core features, 10,000 to 20,000 euros.
Included in the price: Concept & UX/UI design, complete development, PWA optimization, testing & quality assurance, deployment, 3 months support after launch, documentation and knowledge transfer. Optional: SEO, marketing support, long-term maintenance.
We work in partnership: regular video calls, transparent project management, weekly updates, direct contact with the developers. You always have an insight into the progress and can give feedback at any time.
Yes: part-time or full-time developers, code reviews, architecture consulting, knowledge transfer. We work inside your processes and fill the gaps where knowledge is missing.
We can usually start with the conception within 1-2 weeks. For MVPs, we often start even faster. The actual development time depends on availability and project complexity.
No, we work transparently: all costs are discussed in advance and set out in the contract. No hidden fees, no surprises. In the event of changes during development, we discuss the effects openly.
Your satisfaction is our top priority. We work iteratively and regularly gather your feedback. If you are not satisfied, we adapt the PWA to your wishes. Our goal is for you to be delighted with your app.
Yes, we offer continuous further development: new features, updates, performance optimizations. Many customers work with us on a long-term basis. We know your PWA and can develop extensions quickly and efficiently.
We sign NDAs (Non-Disclosure Agreements) and treat your idea confidentially. The code belongs to you, we transfer all rights. We only use open source licenses that have no restrictions for your project.
Yes, we develop complete solutions: APIs, databases, authentication, push notifications, analytics, payment integration. We use modern technologies such as Bun Runtime, Node.js, PostgreSQL and can also integrate existing systems.
