I don't need 'em. As I wrote earlier:
...aside from the database externals included with LC I
rarely use any at all. Most of the things I'd written
externals for in SC are included in LiveCode itself.
For example, here's a list of externals I used to sell in a collection
for SuperCard called scX, with their built-in LiveCode equivalents:
- AskColor
LiveCode: answer color
- CalendarField
LiveCode: we have no one-liner for making an ASCII
calendar layout, but it can be obtained in a one-line
call to the shell on OS X and Linux, and with LC's
weekdayNames and other features takes only a few minutes
to write - but who needs an ASCII calendar? I originally
wrote that because I needed one for an app and doing it in
script was slow - that's very rarely a problem in LC.
- Camera
LiveCode: export snapshot
- ClipToPICTRes
LiveCode: LC supports many resource fork operations,
but since that fork is marked for deprecation there's
little point in using them, and being Mac-specific they
offer nothing for the other 90% of the computing world.
- CmdPeriod
LiveCode: commandKeyDown
- DragThisWindow
LiveCode: mouseMove
- DrawIcon
LiveCode: see note on resource fork above.
- GetFolder
LiveCode: answer folder (much more flexible in LC)
- GetIndString
LiveCode: see note on resource fork above.
- GetVersion
LiveCode: see note on resource fork above, thought it's
worth noting that I now store version info in custom
properties, which can be used for the sorts of things
we used to use the old Mac res fork for, but are much
more flexible, more robust, and available on all platforms.
- GrowThisWindow
LiveCode: mouseMove
- InjectPPAT
LiveCode: backgroundPattern property
- IntersectRect
LiveCode: within
- LineMatch
LiveCode: lineOffset
- ListFonts
LiveCode: the fontnames
- ListRes
LiveCode: getResources
- MonitorRects
LiveCode: the working screenRects
- MoveFile
LiveCode: rename file
- NewFolder
LiveCode: create folder
- PixelColor
LiveCode: screenMouseLoc with mouseColor
- PopList
LiveCode: popup
- RestartMac
LiveCode: one-line call to shell
- SetColorCursor
LiveCode: all cursors can be color
- ShowProgress
LiveCode: built-in progress object
- ShutDownMac
LiveCode: one-line call to shell
- SnapDragon
LiveCode: built-in grid property
- xFileType
LiveCode: the detailed files
- xPrefs
LiveCode: specialFolderPath
Even the externals others wrote that I published for SC are easily done
in native LiveCode, from arrays to lists to statistical functions,
text-to-speech, and much more - easier to work with right in the
scripting language, and unlike externals can be used on multiple platforms.

Check out the LiveCode Market Place:
<https://livecode.com/store/marketplace/>
There are several dozen add-on packages there, and many more throughout
the community.
It's just that with LiveCode's very broad capabilities, relatively few
add-ons are externals per so, with many add-ons being libraries, custom
controls, and other forms.
