Your (git) repository with one or more Contember projects.


Every project contains Contember Schema definition for your simple website, blog or any other content-based platform or database. Optionally any project can have its Contember Interface.


A running Contember Engine server hosting as many Contember projects as you like (and providing their Content API). Each instance has a single Tenant API, so you can store and manage access from a single point.

APIs on a single instance

Content API

The main GraphQL API for your project. It is automatically generated from your schema definition

System API

Is a complementary API for your project. Used to manage schema migrations.

Tenant API

Using this API you can manage users, API keys and project memberships on an instance

Project Schema

Definition of your model, ACL rules and input validation rules.

Project Schema Migrations

Chronologically sorted immutable JSON files containing all schema changes. These files are "source of true" of a schema.


Each operation you make in your data is stored in an event log. This log can be used for history.


Is a special user role. This user is the most powerful user of a system.
