Kosmos

Generative AI operating system

What Kosmos is

Kosmos is a generative AI operating system for integrated work and life. One shell for chat, code, files, and generated apps, with agents that share focus context across every workspace. It is not a chat sidebar bolted onto an IDE: it owns the shell, the workspaces, the agent UX, the app platform and the APIs that clients and the SDK talk to.

The Arco shell

A window frame and a dock, in the real tokens

An illustration rebuilt from the original shell's window frame, dock and dark Arco tokens (accent #7c9dff). It is not a screenshot of the running product, and the conversation is made up. Pick a dock item to switch the window.

$ npm install @kosmos-computer/sdk

$ node hello.mjs
Connected to your Kosmos environment.

Runs everywhere

Platforms and their status

Status tags are copied from the original platforms and download pages. Those pages are live on www.kosmos.computer but sit behind a temporary access gate, so this site treats them as a preview of what is planned, not a launch announcement.

Also: self-host with Docker or Coolify (listed as Available), and Kosmos Cloud for a managed instance (Beta).

Kosmos SDK MIT

Official TypeScript client

Connect your apps, scripts and automations to a Kosmos environment: a local desktop, a self-hosted server or a hosted tenant. Mint an external client token in Settings, External Access. The SDK talks to Kosmos server APIs; it is not the App Bridge SDK for iframe apps inside the shell.

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();

const result = await kosmos.chat.complete({
  message: "Summarize what you can help me with.",
  mode: "ask",
});

console.log(result.text);
