Multi-tenant

One CMS, many tenants

Manage multiple brands, clients, or projects from a single instance. Each organization can have unlimited sites with fully isolated content, users, and permissions.

Unlimited organizations with unlimited sites each
Content and roles isolated per organization and site
Content types can be global or site-specific
Auto-namespaced database views per org and site
Timezone and geographic settings per site
Users can be members of multiple organizations simultaneously

API-first delivery

Auto-generated REST endpoints

Every content type automatically generates a namespaced database view — accessible via REST, Supabase client libraries, or direct SQL. No custom endpoints to write or maintain.

Views named by organization + site + content type
Only published content exposed via public views
Users can issue and revoke their own API keys
API keys secured with HMAC in Supabase Vault
Endpoints for resource management and content preview

Generated view name

Pattern

{org}_{site}_{content_type}

Example

acme_corp_main_site_blog_posts

Query directly via Supabase client, REST, or PostgREST. Only published entries are included.

User Management

Roles & Hierarchy

Custom Permissions

Create permissions in any category and attach them to any role

API Key Auth

Organize files with folders and tags
Automatic image resizing and optimization

Content localization

Per-field translations with fallback to default language

Locale tabs

Dedicated editor tab per enabled locale in the content editor

Dashboard i18n

Separate multi-language support for the admin UI itself

Content type level

Enable or disable localization per content type

Localization

Built for multilingual content

Enable localization at both the content type and field level. Each locale gets its own tab in the editor, with automatic fallback to the default language. The admin dashboard itself also supports multiple UI languages independently.
