Multi-site hosting
One account, many named sites — each with its own memorable URL, managed from the Settings panel.
Open in the interactive manual →The interactive version has full-text search, a table of contents, and light/dark themes.
One 3dCMS account can host several named sites side by side — a portfolio, a showroom, and a one-off launch page, all from the same editor. Manage them in Settings ▸ Sites.
Your handle and your URLs
Your handle is the personal part of every publish URL:
https://3dcms.info/<handle>/sites/<slug>/Set it on your Account page. It's editable until your first publish, then locked — so links you've already shared never break.
The primary site
Exactly one site is the primary. The primary additionally answers at the bare-domain (root) URLs, so it's the "front door" of your domain. Set it with the Primary button on a site row.
The active site
Publishing always targets the active site. In the Sites list, each row has:
- Edit / Editing — make this the active (publish-target) site.
- Primary — make this the primary (front-door) site.
- Delete — remove it (disabled when only one site exists).
Creating a new site
Under "Add a new site," enter a Slug (lowercase letters, digits, hyphens) and a Display name, pick a starter template, and click Create site. 3dCMS seeds it from the template and publishes it right away, so there's something live immediately.
