SaaS plugin
Introduction
The Maglev SaaS plugin (maglevcms-saas-plugin) extends Maglev core so you can run a multi-site, multi-theme page-builder platform inside your own Rails application—the same model as the legacy Maglev PRO gem, built for Maglev v3.

The open source Maglev gem targets a single site per app. The SaaS plugin removes that limit: signed-in users can create and manage many sites, pick from the themes you ship, and edit content in the Maglev editor.
Typical use cases:
- Franchisors — give each location its own site from one Rails app.
- Agencies — spin up microsites or campaign landings without a separate CMS product.
- SaaS products — offer a site builder as part of your platform, on your infrastructure.
