ZeeCreatives MultiSites

WordPress Multisite gets you most of the way to a SaaS product. Where it stops short is isolation. Every site in a standard multisite network shares one database, distinguished only by table prefix. For a magazine network that is fine. For a product where each subdomain is a paying customer's workspace, it means one customer's data sits in the same database as everyone else's, backups are all-or-nothing, and migrating a single customer out means extracting their tables by hand.

ZeeCreatives MultiSites addresses that directly: each subdomain gets its own database and its own uploads directory, provisioned automatically, with a REST API so provisioning can be triggered by your signup flow rather than by an admin clicking through screens.

The plugin sits on top of WordPress Multisite in subdomain mode rather than replacing it. When a new site is requested — through the admin or the REST API — it provisions the database, creates the uploads directory, registers the site in the network, and activates the configured default theme and plugins.

Because provisioning is exposed over REST, the natural architecture is that your billing or signup system calls the endpoint when a plan is purchased and the workspace exists moments later. Nobody waits on manual setup, and the provisioning path is the same one every time.

The database-per-site design is the significant architectural decision and the one to be deliberate about. It buys real isolation and per-tenant operations. It costs you a database count that grows linearly with customers, and any cross-site reporting has to be built rather than being a single query.
