About Entity OS
We believe building software should be about defining what your data is, not writing boilerplate.
Our Mission
Entity OS was built on a simple idea: everything is an entity. Instead of writing code to manage state, handle events, and enforce access control, you define your data types as schemas and let the runtime handle the rest. We want to make building applications as straightforward as describing what they should do.
What We Do
Entity OS is a universal, observable, event-driven runtime. It provides a schema registry for versioned types, an event bus with full observability, capability-based access control, a sync engine for multi-tier storage, and domain event rules for reactive behavior. All with zero dependencies.
Whether you are building a design tool, an email platform, a project manager, or something entirely new, Entity OS gives you the primitives to ship faster and iterate with confidence.
Our Values
Simplicity
Data, not code. Schemas, not classes. Events, not callbacks. We choose the simplest abstraction that works.
Observability
Every state change is an event. You can see exactly what happened, when, and why. No black boxes.
Zero Dependencies
We control every line of code. No supply chain risk, no version conflicts, no surprise breaking changes.
Open by Default
Your data is yours. Export it, migrate it, inspect it. No lock-in, no proprietary formats.
