  2. as Progress Web App
  3. as Standalone Desktop (Electron) App Offline Cache

After is loaded, it can automatically be used offline without requiring an Internet connection.

That’s to say, once you have loaded online (with an Internet connection), if an Internet connection is not available later on, all web archives already loaded will continue to be available because it’s cached.

To do this, in your Chrome browser, and the site will start loading local archives even without an Internet connection.

What's cache?

Cache is a temporary storage space in your browser that keeps certain files. Cached data is used to quickly load an application or website (like!) every time you log on. as Progress Web App can also be installed as Progressive Web App and be available as a standalone app on desktop and mobile.

These type of apps use the same, current version of Chrome you normally use while searching or browsing the web. This is still experimental, but should provide the same behavior as regular

To do this, on the site, you might have noticed a “new window icon” in your search bar. Clicking on this icon will open the progressive web app on your computer so you can use it offline.

What's a Progressive Web App?

Progressive Web Apps can be considered as a cross-platform app: part web and part native. PWAs are built on the web and has web features that make is faster and easier to discover and share.

Although the Web Page/Progressive Web App versions have almost the same features, the standalone App is useful for two primary reasons:

1) For viewing web archives that contain Flash. Flash is not supported by default in most browsers and will soon be removed. The App will bundle a Flash plugin to continue to make Flash accessible for web archives.

2) Primary use for viewing offline web archive. If your primary use is to view web archives stored locally, the App is a better option, as it provides direct access to the file system. Once loaded, App can continue to load web archives from disk. The desktop app fully replaces Webrecorder Player

When using, you may be asked to re-open a local file because a web site can not have persistent access to your file system.

What's a standalone desktop (Electron) app?

Electron is the framework being used for a native application. A standalone desktop app just means that you can download the application to your desktop and open it up whenever without Internet!
