One or multiple projects to scale properly?

Hi, I’m building a CRM + payment forms. There are 3 parts

  • My website / with a blog
  • The app / CRM
  • The landing page + payment forms my client will generate with the CRM app

Question is : do I have to put all in a single project or split into 3 projects ?
1 project : www.mycrm.com
1 project : app.mycrm.com
1 project : page.mycrm.com

Please explain how project pages are loaded. once ? when you navigate ?
does splitting into multiple project affect performance ?
Is there a reasonable number of pages not to exceed ?
collection static/dynamic/cached for a blog ?
collection static/dynamic/cached for the client pages/payment forms ?

Hey, as much as I love WeWeb, you might want to go for a website/blog with something else like webflow.
Maybe also a landing page. Then handle the business logic with Weweb app/crm
