# Cordango

> Build complete business applications from a definition you own.

Cordango is an open application language and a deterministic compiler. You describe what an
application should do, and Cordango turns that description into a working application.

The description is the artefact that matters. It is called an **App Definition**, and it is the
same file whether you run the application on the Cordango Platform or generate a standalone
project and host it yourself.

<Note>
  Cordango is pre-alpha. The language, the CLI and the generated output all still change between
  releases.

## The two products

<CardGroup cols={2}>
  <Card title="Cordango Open Source" icon="box" href="/cli/install">
    Builds one application. Its own backend, frontend, database, users, authentication and
    permissions. Not multi-tenant, no AI at runtime, and no dependency on us once it is generated.
  </Card>

  <Card title="Cordango Platform" icon="building" href="/api-reference/introduction">
    Connects and governs many applications as one company system: shared people and organizations,
    cross-app references, audit history, AI, search and managed hosting.
  </Card>
</CardGroup>

The same App Definition works in both places. What differs is what each target supports, and every
target says so out loud rather than quietly dropping what it cannot do.

<Note>
  **Platform features are currently in invite-only beta.**
  [Sign up here](https://www.cordango.com/beta/) to be considered for one of our next phases.
