Please don't feel obligated to answer if you can't, but why can't you use FOSS libraries like Laravel? Are you not even allowed to use MIT licensed stuff? What industry do you work in?
I pushed hard and was able to get us to the point where stuff runs in PASE with modern languages (like PHP).
It’s not any specific licensing issue, just organizational distrust of anything that isn’t paid for.
So when we needed a wiki (before confluence was bought and we only had file shares) I put dokuwiki on a server that already had apache and PHP from years prior. When we wanted to build internal web guis for automation and jobs, we used Bottle.py, since it can run a web server and operate without installation - just copy and paste the library.
Tldr bureaucracy leads to shadow IT.
