ObjectStack Protocol

ObjectStack is a Metadata-Driven Protocol for building enterprise applications. Define Data, UI, Automation, and AI as structured metadata — ObjectStack handles the rest.

npx @objectstack/cli init my-app && cd my-app && os studio

Open http://localhost:3000/_studio/ to browse objects, test APIs, and inspect metadata.
