A project for high loads and special scenarios: headless architecture or API-first, advanced offline with queues and background synchronisations, extended SEO for PWA. If necessary, we will package the application for the store (TWA/Capacitor) and provide SLA support. Development includes:

PWA (Progressive Web App) is a technology that allows a website to function like an application: open instantly, work offline, and send push notifications.
Such an application is installed directly from the browser, without the App Store or Google Play, and uses all the capabilities of the device — from the icon on the screen to the camera and GPS.
The basic version of PWA costs from £800 and takes 2–3 weeks. Advanced solutions with push notifications, cache and integrations take 3 to 6 weeks.
The timeframe depends on the complexity of the interface, the availability of integrations, and the condition of the current website. After analysis, we prepare an accurate estimate and work plan.
We create Web App Manifest, Service Worker, adapt the design for mobile devices, and optimise performance according to metrics Core Web Vitals.
If necessary, we add push notifications, analytics, CRM and payment integrations — we select a set of features tailored to your business goals.
Push notifications are connected via OneSignal or Firebase — users receive news, discounts and reminders directly on their phone screen.
Offline mode is implemented using Service Worker: content that has already been opened is stored in the cache and is available without the internet.
PWA fully preserves page indexing — search engines see the site structure in the same way as before implementation.
Additionally, we configure meta tags, sitemaps, and micro-markup to speed up indexing and improve search engine rankings.
No, that's the advantage of PWA — installation happens directly from the browser. The user simply clicks ‘Add to screen,’ and the icon appears next to other applications.
If desired, we can package PWA for the App Store and Google Play using Capacitor or TWA technologies CapacitororTWA.
All you need to do is provide access to your current website, analytics, and logo. We will conduct an audit and propose the optimal PWA architecture.
If you already have a designer or a team of content managers, we will connect them to the process via a staging environment.
After release, we stay in touch: we monitor metrics, optimise the cache, and update libraries as new versions are released.
Under the SLA agreement, we can take care of regular updates, monitoring, and incident response 24/7.
