Concepts

Understand how Nebula works — from its data model to real-time processing to access control. Each concept builds on the previous, but they can be read independently.

Data-First Design

Entities, components, and the relationship graph that replaces traditional data modeling. The foundation everything else builds on.

Behaviors

Declare what data you care about with composable queries. Nebula routes matching entities to your systems automatically.

Orchestration

How entity changes flow through checkpoints, queues, and worker pools to reliably trigger the right systems.

Access Control

Principals, roles, per-component policies, and a hierarchy model that handles real organizational structures.

Component Design

Schema definition, validation, rich property types, and the evolution model that prevents breaking changes.

Scripted Systems

Write and deploy system behaviors directly from your app with instant feedback and revision history.
