在Laravel / MVC上使用第三方脚本/应用程序

I'm new to Laravel and some MVC theory, so I have been doing some research as to the best way to use third-party scripts and applications within Laravel (this question, however, certainly applies to any MVC framework). Unfortunately, I have not found an answer to my question so I thought it would be helpful to myself and others to ask it here!

Basically, I have osTicket and I wish to use it in my Laravel setup. Since osTicket is it's own, third-party application, where is the best place to upload this within my Laravel installation? My initial thought is /public/, but the little documentation I read on /vendor/ makes me think it belongs there.

Would love best practice advice on where this should go...thank you!
