SWFObject

[2][3] The library can also detect the installed Adobe Flash Player plug-in in all major web browsers, on all major operating systems (OS), and can redirect the visitor to another webpage or show alternate HTML content if the installed plug-in is not suitable.

The developer may interface with the library in a standardized manner, the minimum being a single line of JavaScript code.

[13] For websites that aim to reach the widest possible audience an alternate method is available, by using standards-compliant HTML markup to embed the Flash movie (typically using the tags for the best browser compatibility[14]), and using the registerObject() function within the library's API[15] to register the Flash content enabling usage of the other features that the library provides.

[19] SWFAddress is a JavaScript and ActionScript library that allows Flash websites to support deep linking, and can automatically integrate with SWFObject.

SWFFit (formerly known as FitFlash) is a JavaScript library used to resize Flash movies according to the browser window size, keeping it accessible independent of the screen resolution.
