Introduction
Applications as graphs. Intelligence on the same substrate.
Closure Platform is the runtime for Semantic Applications — software whose UI, workflows, AI, integrations, and governance live in one governed product graph. Systems of record stay authoritative; Closure seals work back into them.
These docs are the practical layer: how to build, run, and operate on Closure. The narrative layer — why Semantic Applications exist and where they lead — is the book, The Last Application.
The short version
- Everything product-shaped is data — pages, workflows, skills, connectors — as typed JSON-LD DataObjects.
- Closure is the runtime that stores, authorizes, runs, and renders that graph.
- You build from your IDE — one install, Connect in Cursor, then craft on the live org graph. Your agent learns the paradigm from the runtime itself (the authoring contract) and ships through the same gates as every other author.
- You seal results into Form.io, ServiceNow, Slack, email, and other systems of record.
How the product is organized
| Layer | What it is | The four |
|---|---|---|
| Pillars | What you author — the atoms of a product | Experiences · Workflows · Knowledge · Integrations |
| Ops | How the runtime executes, remembers, judges, steers, and ships | Runs · Events · Issues · Goals · Versions |
Pillars are the building blocks. Ops is the living loop + release control plane — not a fifth pillar.
