I will turn your website into an installable PWA with offline support and push

I will turn your existing website into a fast, installable Progressive Web App with reliable offline support and working push notifications — no rebuild, no framework lock-in.

What you get

• A production-ready Web App Manifest (manifest.webmanifest) wired into your pages, with name, short name, theme/background colors, display mode, scope, start URL, and orientation tuned for your brand.
• A complete icon set generated from your source logo: maskable icons, Apple touch icons, and the favicon sizes modern browsers expect, plus the <meta>/<link> tags that make them load.
• A hand-written service worker (no opaque boilerplate dump) implementing a caching strategy chosen for your content: cache-first for static assets, stale-while-revalidate for semi-dynamic pages, network-first with timeout for API calls.
• Offline support — a custom offline fallback page, cached core routes, and precaching of your critical CSS/JS/fonts so the app opens and stays usable without a connection.
• A working install experience: a controlled "Add to Home Screen" / install prompt with your own button and copy, instead of the silent browser default, plus correct behavior on iOS, Android, and desktop Chrome/Edge.
• Web Push notifications end to end: VAPID key generation, a subscribe/unsubscribe flow, the client-side push/notificationclick handlers, and a documented payload format your backend can POST to. A minimal send script/snippet is included so you can fire a test notification on day one.
• Smart cache versioning and update flow so new deploys don't get stuck behind a stale service worker — including a "new version available, refresh" pattern you can keep or remove.
• A Lighthouse PWA pass: I run the audit and resolve the installability and best-practice items that are in scope, then hand you the before/after report.
• A short handover doc explaining what was added, how to change cached routes, how to send a push, and how to bump the cache version when you deploy.

How it works

1. Share your site. Send me the live URL plus access to the codebase or the ability to add a few files (manifest, icons, service worker, and the registration snippet). Static sites, server-rendered apps, WordPress, Shopify themes, and most JS frameworks all work.
2. Audit & plan. I review your stack, hosting, and HTTPS setup, run a baseline Lighthouse audit, and map which routes and assets should be cached and how. You get a short plan before I build.
3. Build the PWA layer. I generate icons, write the manifest, author the service worker with the agreed caching strategy, and wire in registration. For push, I set up VAPID keys and the subscribe flow.
4. Test across devices. I verify install on Android and desktop, confirm the iOS add-to-home-screen behavior, pull the network cable (literally — offline mode) to confirm the app loads, and send a real test push.
5. Review & revise. You install it yourself and try it offline. I refine copy, icons, cached routes, or strategy within your plan's revisions.
6. Handover. You get the files, the doc, and a clear path to maintain it.

Why choose this

I write the service worker by hand and explain every line, so you own maintainable code instead of a generated black box you're afraid to touch. The caching strategy is matched to your content — a blog, a store, and a dashboard each need different rules, and I don't apply a one-size template. I test offline behavior and push on real devices, not just in a single desktop tab, because iOS in particular has quirks that only show up on a phone. And I keep your stack: no migration, no rewrite, no new framework — the PWA layer sits on top of what you already ship.

Who it's for / use cases

• E-commerce and content sites that want an installable, app-like presence without building a native app.
• SaaS and dashboards that need offline-tolerant views and re-engagement via push.
• Local businesses and events wanting a home-screen icon customers tap instead of typing a URL.
• Agencies and developers who need the PWA layer done cleanly so they can focus on features.
• Anyone failing the Lighthouse "installable" check who wants it resolved properly.

FAQ

Q: Will this slow down or break my existing site? No. The PWA layer is additive — manifest, icons, and a service worker that I scope and test. If anything looks off in review, I adjust the caching rules; nothing about your current rendering changes.

Q: Does push really work on iPhone? Yes, on iOS 16.4 and later, but only after the user installs the app to the home screen — that's an Apple requirement, not a limitation of my work. I set it up correctly and tell you exactly what your iOS users need to do.

Q: I'm on WordPress / Shopify / a no-build static site. Is that fine? Yes. As long as I can add a few files and serve over HTTPS, the approach works. Some platforms need a small plugin or theme edit, which I'll handle or document.

Q: Do I need a backend for push notifications? To send pushes, you need somewhere to POST the payload from — I provide the keys, the client handlers, and a minimal send script. Wiring it into a large existing backend or a scheduler is possible as an add-on if you'd like.

Q: What do you need from me to start? The live URL, your logo in a high-resolution square format, and either repo access or the ability to add files to your project. Confirmed HTTPS is required for service workers to run at all.

Q: Will the app update when I deploy new content? Yes. I include cache versioning and an update flow so users get fresh content instead of being stuck on a cached version. The handover doc shows how to bump the version on each deploy.

Q: Can users actually install it, or is it just "offline"? Both. A valid manifest plus the service worker makes it genuinely installable with its own icon and window, and I add a custom prompt so the install option is visible rather than hidden in a browser menu.

Q: What if I only need offline support and not push? The Basic plan covers the installable, offline-capable PWA without push. You can always add push later, and the architecture leaves room for it.
