Why CheerpX For Flash

By combining the CheerpX virtualization technology with the Adobe Flash Player, CheerpX For Flash provides an easily-integrated, HTML5 middleware library that allows normal browsers to continue using Flash applications without a plugin. No special browsers or installable components are required by the users, and no change to the Flash application is required.

CheerpX For Flash runs securely, fully client-side, on normal browsers, without any local installation or requirement. Available to both Flash developers and integrators, it does not require access to the source code.

Preserve Vital Applications

Continue supporting your internal, customer-facing or public-facing applications after the deprecation of Flash, without doing a full HTML5 rewrite.

Secure by design

CheerpX for Flash works on modern browsers, reducing the risks of keeping a legacy browser running. Thanks to HTML5 sandboxing, it radically improves safety compared to the Flash player.

Ease of access

CheerpX for Flash can be used for external B2B and B2C applications, as it doesn’t require users to download or install anything specific to your application.

HOW CHEERPX FOR FLASH WORKS

Three key components

Adobe Flash runtime

A commercial build of the Adobe Flash runtime is at the core of CheerpX For Flash. This allows any existing, unmodified application to run with CheerpX For Flash, with no deadlines.

CheerpX

The Flash runtime is run by an HTML5 ’emulator’ based on CheerpX, on the user browser. It executes fully client-side, without the user noticing.

HTTP Hosting

The Flash Player and CheerpX are hosted on any HTTP server. CheerpX For Flash is integrated on any Flash HTML5 page by adding a one-line script to the page.

CheerpX for Flash is an easy-to-integrate solution to seamlessly extend the life of existing Flash applications, without special browsers or any action from the user.

Easy Integration

CheerpX For Flash can be integrated easily on both static and dynamically-generated pages.

If you can, simply add a single <script> line to your HTML <head> and your application will run on modern browsers without installing Flash.

For dynamically-generated pages, you can integrate CheerpX For Flash with a browser extension (deployable with GPOs if required), or with a reverse proxy.
