JSFX are distributed as text files, not binaries, and they can even be edited on the fly while the DAW is running. I don't think they can be called VSTs, but they sure are extremely powerful (I have written a couple myself). JSFX can also be run in most DAWs using ReaJS, a JSFX VST host written by Cockos (not updated in a while, so some recent features of the language won't work), or another similar thing called YSFX. Playtime probably uses Reaper-specific API calls and UI manipulation, but why the author chose to write a Reaper-specific VST instead of a plugin, IDK.

> I don't think they can be called VSTs They aren't VSTs but that's my point. A "Reaper plugin" to the community usually means a JSFX plugin. Playtime is a VST plugin, not a JSFX plugin, but it also relies on Reaper specific API calls making it incompatible with other DAWs that support VST. It matters because you'll find it in the VST section of your Reaper plugin list and I believe Steinberg also requires you to use the VST branding on any plugins using the VST SDK VST isn't an open plugin format and it doesn't guarantee compatibility across all hosts. It's a source-available format owned by Steinberg who grants financial free use of it (but not free use in the FOSS sense)
