Build apps with entities, not code
Entity OS is a universal, observable, event-driven runtime. Define your data as entities, wire up events, and ship — everything else is handled for you.
Everything you need
A complete runtime for entity-driven applications.
Schema Registry
Versioned Types
Define entity types as data, not code. Versioned schemas with inheritance and chained migrations keep your data evolving safely.
Event Bus
Observable Everything
Every state change emits an event. Pattern subscriptions, auto-instrumentation, and full replay — observability is intrinsic.
Access Control
Capability-Based Security
Bus-level enforcement that cannot be bypassed. Per-entity overrides, owner tracking, and scoped execution contexts.
