:The closed-source proprietary reference implementation by Adobe, who discontinued it in 2020. The web version relies on [[wikipedia:NPAPI|NPAPI/PPAPI]], an obsolete browser plugin system that for many years only stuck around specifically because of this Flash pluginPlayer; when the plugin was officially dropped by Adobe, so too was the plugin system dropped by all the major browser vendors. The desktop player version is still available for download from the debug downloads section of Adobe website's debug downloads sectionwebsite, and Harman International is also [https://airsdk.harman.com/flashplayer maintaining an extended support version specifically for enterprise users].

::A payware HTML5 software package which combines basically just takes Harman's version of Flash Player and uses CheerpX, an x86 emulator in WebAssembly, with Harman International's extended support version of Adobe Flash Player as a way of basically just getting the original Flash Player code to make it run in a modern browserbrowsers. No-one on this wiki has had the chance to properly evaluate it, but we would 'd expect reference-level accuracy at the cost of woeful performance.

:A C++ implementation that's designed specifically to provide a drop-in FLOSS alternative to replacements for both the desktop and NPAPI versions of Adobe Flash Player. Says it has 79% of the APIs covered as of January 2022.

:A desktop-only C++ implementation that's technically still active but has made very little progress since early 2012went inactive in 2017, which with the most recent stable release dates dating back to2012. It focuses on older versions of Flash that Lightspark was historically less focused on supporting properly, hence why Lightspark could (and still can) use Gnash as an automatic fallback if both are installed simultaneously. However, newer versions of Lightspark have all but completely superseded Gnash and there's not much reason to use it anymore.
