you mean they share a database?
If you don't need different themes, you can just set up 2 Site
objects, and create your entries, using single byteflow instance.
If you need different themes, I'm afraid you have to use 2 different
instances with different settings_local.py files (unless you like to
manually create a theme that will render differently for different
sites).
They can share a database, you just set up Site objects for domains you use.
And when you add posts, choose correct site.
