How to make a website builder?

Question

Laravel

Can you suggest articles and frameworks for creating a multisite, that is, one admin panel could edit several different sites.

Answer 1

Admin panel - as a data management system that is stored in some kind of database
Sites that can be on anything uses data from this database. Shared tables, API requests, and so on…
In addition to combining data, multisite can also combine common files.
For example, you can specify in the nginx config that for domain1/domain2/domain3 app.php is in one place. And in the app.php itself, depending on the domain, do something different.
