Cloud-based or self-hostable

You can host CheerpX on public or private clouds, or private airgapped networks. CheerpX does not require a backend other than an HTTP server.

How it works

Three key components

Adobe Flash Player

The Adobe Flash Player and its full runtime are at the core of CheerpX for Flash. This allows any existing, unmodified application to run with CheerpX for Flash.

CheerpX

The Flash Player 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.
