WHAT WE DO

Everything your PWA needs

From greenfield builds to legacy upgrades — we cover the full lifecycle of browser-native apps that work without an app store.

PWA Development

Full-stack progressive web apps built from the ground up — accessed instantly via any browser, no installation, no gatekeeping.

🔍

PWA Audits

Deep analysis of your existing web app: Lighthouse scores, Core Web Vitals, service worker coverage, and offline resilience.

🚀

Performance Tuning

Sub-second load times, perfect Lighthouse scores, and interactions so smooth users forget they're in a browser.

🔧

Maintenance & Support

Ongoing monitoring, updates, and improvements. We keep your PWA healthy, secure, and ahead of browser changes.

📡

Offline & Sync

Service worker strategies, background sync, and caching that make your app work reliably on flaky networks or no connection at all.

🔔

Push Notifications

Re-engage users with timely, targeted push notifications — no native SDK, no app store, just the open web.

WHY PWA

Feels like an app.
Lives in the browser.

A PWA is a website engineered to behave like a native app — without asking users to visit an app store, approve a download, or manage updates.

  • Open a URL — that's it. No install prompt, no friction
  • Works on any device: phone, tablet, laptop, desktop
  • Offline-capable with service workers and smart caching
  • Push notifications via the browser, no native SDK needed
  • Updates silently in the background — users always have the latest
  • Shareable, linkable, and indexed by search engines

HOW WE WORK

Simple, transparent process

No surprises. No scope creep. Just a clear path from idea to shipped PWA.

01

Discovery

We understand your users, your product, and your constraints — then define the right PWA architecture and offline strategy.

02

Design & Prototype

Interactive prototypes with app-shell UX, offline flows, and push notification patterns — signed off before a line of code is written.

03

Build

Component-driven development with CI/CD from day one. Lighthouse checks on every pull request. No app store, no waiting.

04

Launch & Monitor

Deploy to a URL and you're live — instantly accessible to every user on every device, with real-user monitoring from day one.
