Web (PWA) Hosting

Primio can host your app as a Progressive Web App (PWA) for free. You get a unique URL that anyone can visit — no app store required.

How to publish

Open the Publish section

Go to Workspace → Publish → Web tab.
Click “Publish for free”

If you’ve published before, the button says “Update for free” instead.
Wait for the build

The build takes about 3 minutes. You can see the progress in real time.
Copy your URL and share it

Once the build completes, your app is live. Copy the URL and send it to anyone.

Updating your app

Publish again anytime to push changes to the same URL. It’s always free. Your visitors see the latest version the next time they open the link.

What’s a PWA?

A Progressive Web App runs in the browser but can be installed on a user’s home screen like a native app. PWAs support offline access and push notifications (if your app implements them). They work on any device with a modern browser.

How users install your PWA

Your visitors don’t need to install anything to use the app — it works in the browser. But they can optionally install it for a more native experience:

Mobile (Android/iOS): Tap the browser menu and select “Add to Home Screen.” The app gets its own icon and opens without browser chrome.
Desktop (Chrome): An install icon appears in the address bar. Clicking it installs the app as a standalone window.

When to use web hosting

Quick sharing with friends, clients, or testers
User testing and collecting feedback
Client demos and presentations
Simple web presence for your project

Limitations

No app store listing — users find your app through the URL, not by searching a store
Some native features (camera, Bluetooth, NFC) may not work in web mode
Performance is good but not identical to a native APK or IPA build
