Has anyone made any third party modules for MES - not sepasoft

I’m interested to see if anyone else has developed MES modules or base projects with scripting for MES functionality.
Interested in parts track & trace, production scheduling, erp backflush (SAP)

I know sepasoft was set up by one of the ignition founders or similar so see the close link - just wondered if there are alternative modules that do the same?

We've done all these with Ignition's out-of-the-box features + some Java libraries (it's extremely low on my priority list, but I'd eventually like to make a module to wrap up some OptaPlanner functions).

Nothing against Sepasoft, but I generally prefer to have complete control over the workflow/terminology.
