Progressive Web App, PWA | PWAs Kraków Poland

01Our PWA development offer

In the ever-changing digital era, progressive web application development adds to your expertise. Each step is huge in manifesting the ideas into applications that perform well and combine functionality with user experience. We use the most current JavaScript technologies-for example, using React and Next.js to create a front end, then providing it with a strong Node.js back end, which together realize the aesthetically appealing, responsive, and intuitive solution that is your application. No matter whether you need to build anew from scratch or update your current application, you can depend on our team to be clear and swift in reaching your goal. It is all about communication. And when the limitations of a PWA do become restrictive, transitioning to a fully native app becomes simple with us, easy on both iOS and Android. Innovation is within reach with us - let's create something memorable together.

End-2-end PWA development

We take every stage of progressive web app development seriously - from prototyping to production. We'd design, build, and polish in the latest JavaScript technologies and with a strong Node.js backend to ensure a smooth ride from minute one. Whether it's a tight MVP just to test the waters or a fully polished solution ready to be scaled, we will deliver it in no time. Nothing fluffy, no unnecessary delays, just a sharp product very well executed. We also wouldn't bore you with details about CI/CD, deployments, or ongoing support, but you can rest assured that that is already in the cards. That's how we roll.

Frontend in JS - React / Next

Got an API? Great. We’ll bring it to life with a clean, fast, and highly interactive frontend. Whether you need a PWA built from the ground up or improvements to an existing one, we make it seamless. React is our core expertise, and when it comes to Next.js, we know it inside out. SSR, ISR, performance optimizations—whatever your project demands, we deliver. No unnecessary complexity, just a smooth, efficient frontend that feels right.

Development of APIs

In PWA development, it’s rare to require just backend services, but if you have your own frontend team, we can deliver the robust backends and APIs you need using Node and NestJS. Our development approach is detailed and thoughtful, ensuring every component of you PWA works harmoniously, even as your needs expand. Plus, we emphasize clear, ongoing communication, clear api docs, to keep your frontend team updated every step of the way, ensuring that what we build today is ready for tomorrow’s challenges.

UI and UX design

Want to shape your application’s design and prototype it before diving into development? Makes perfect sense. We’ll guide you through the process, refining user flows, interactions, and visuals to create something that feels intuitive and modern. Or maybe you already have a development team ready to go but lack a high-quality, state-of-the-art UI. We step in there too, delivering sleek, thoughtful designs that not only look great but enhance usability. Design isn’t just about aesthetics—it’s about making the experience seamless, engaging, and built for real users.

Migration to a native app

If your PWA is hitting a wall with limitations, we can transition it to a fully native app. With our expertise in React Native, we unify iOS and Android development under a single, efficient codebase—no duplicated effort, no unnecessary complexity. Some features might be achievable within your existing setup, while others may require a full migration. We’ll assess your case, give you a straight answer, and execute the best approach. Whether it’s performance, offline capabilities, or deeper hardware integrations you’re after, we’ll make sure your app delivers the experience your app users expect.

Deployment and maintenance

No guesswork. No vague assumptions. Before we ever touch the code, we seriously plan. PWA is not a website, not by a long shot, and treating it like one is absurd. First of all, we'll do competitive analysis, looking not to copy what's out there, but to uncover what gaps there are, what performance issues we may encounter and where we may improve the user experience. Then - requirements gathering: not just what features do we want, but how is it supposed to behave offline, how will it manage data sync and how fast does it load under actual network conditions. From there, roadmap. Not a one-time document, but a strategy that lives on as we move forward, checking for performance, scalability and security. And cost and time estimates? Not mere ballpark estimates, these complexity glitches-the service workers, caching strategies, APIs-all get broken down for projections that will actually hold in execution. Not everyone enjoys an endless gloom of development.
