📦 Export your app on PWA (multiOS installation)

The PWA tab of the Publish window directly exports a Progressive Web App: a web app that installs on desktop and mobile, and works offline. This export requires a Pro plan (without it, the button at the bottom becomes « Upgrade »).

1. Click on Publish

in the top bar of your project, then choose the PWA tab.

2. Fill in the PWA fields

• Window title: the title of the browser tab;
• Progressive webapp name and Progressive webapp short name: the name shown under the icon on the home screen (the short name is used when space is tight);
• Progressive webapp icon: a 512 × 512 pixel image, otherwise Celestory rejects it.

The Export button stays greyed out until the name, the short name and the icon are filled in.

3. Choose the version, then click on Export

A notification « App exported! You will receive an email with the link to download it. » appears.

4. Download the zip received by email

It contains your ready-to-use web app: the index.html file and the PWA's manifest.json file, already filled in with your app's name.

5. Host the content of the zip

Unzip it and put its content on HTTPS web hosting (your website, or a static site host): a PWA can only be installed from an HTTPS address. Then share the address of the index.html page.

6. Install your app

ON CHROME DESKTOP

Click on the + appearing on the right of the url.

Then click on the Install button.

Your app is fully installed and avaible offline like other Windows or MacOS App. You  get a shortcut that you can pin on your task bar.

**
ON CHROME MOBILE**

Or any mobile chromium (based on chrome) browser, you will see a contextual button to Add your app to Home screen.

Click on it and you app is now available on your Android or iPhone like any other app.

As you share the link, there are 2 ways to restrict the access to your app:

• You can set a generic password in your app directly.
• You can embaded the link to install your app into a web page with a generic password, or in any way you can filter the user accounts (email, private shared documents, plateform with accounts).

🌟

Congratulations, your app is now installed on the device of your audience. As it is a PWA installation, the weight of the app is very light. As it's only adding files into the local storage of your browser and doesn't have any interaction with your device system, you can install it on any professional device without any IT permissions.
