The generative AI operating system.

• Stable shell prototype

  A navigation rail, windows and workspaces that stay consistent while agents and apps change underneath.

• Agent surface prototype

  Chat and tools that share which workspace, window and entity are in focus.

• Generated apps prototype

  Interfaces assembled from Arco tokens, components and blocks, rather than pasted as text.

• Hosted or self-run available

  Kosmos Cloud for a private managed instance (beta), or run it locally or self-host with Docker.

Sources: docs guide kosmos/what-is-kosmos, kosmos/run-locally, kosmos/self-host. The app itself is a prototype repository; a running shell was not rendered for the archive.

When an agent generates UI, Kosmos provides the context (workspace, window, entity in focus), Arco provides the valid blocks and props, and a registry validates the output. The registry is planned; the tokens and primitives are prototype.

Sources: docs guide kosmos-vs-arco, what-is-arco. Components, tokens and the live demo are on the Arco page.

npm install @kosmos-computer/sdk

import { KosmosClient } from "@kosmos-computer/sdk";

const kosmos = new KosmosClient({
  baseUrl: process.env.KOSMOS_URL!,
  token: process.env.KOSMOS_TOKEN!,
});

await kosmos.ping();

for await (const event of kosmos.chat.stream({
  message: "List my calendar events for today",
  mode: "agent",
})) {
  if (event.type === "text_delta") process.stdout.write(event.delta);
}

Packages: @kosmos-computer/sdk and @kosmos-computer/types. You need an external client token from Settings, External Access, and Node.js 22 or later.

Sources: docs sdk/overview, sdk/getting-started; repository Kosmos-computer/kosmos-sdk (MIT).

1. Install Node.js 22 or later, then clone Kosmos-computer/Kosmos.
2. From the repository root run:

   npm install
   npm run setup   # first run
   npm run dev     # shell :4610, API :4600

3. Open http://localhost:4610 and complete the install wizard (model mode, then owner account).
4. Want it managed? Sign up for Kosmos Cloud (beta), or self-host with Docker.
