Multitenancy with Laravel is a course and package offering that I've been working on for some time. It covers everything you need to do to get started with multitenancy and Laravel.
Mulitenancy is a software architecture that allows a single instance of software to server multiple tenants as if each were a separate instance.
Multi-tenancy seems to be a hot topic at the moment, with many hoping that Laravel Nova was going to solve all of their issues. There are a lot of packages out there that aid you with your multi-tenanted endeavour, but it doesn't have to be that complicated. Honestly.
