Antigravity in the cloud.

A dedicated Linux machine provides browser VS Code and Antigravity in the terminal. Authentication uses Google-account sign-in on the machine, with no API-key option.

Sign in

Google-account sign-in inside the machine; no API key.

Antigravity has no API-key path. After selection at launch, the agy command in the terminal prints a Google sign-in link. Completion of that sign-in makes it ready. The credential stays inside that codespace, so a new codespace requires another sign-in. Antigravity is terminal only on Oyren: it does not run as an Agent app, and the launch list marks it experimental.

# No key to set. Sign in with your Google account when agy asks, inside this codespace.
agy

Oyren credits and API keys do not apply to Antigravity. It runs on the signed-in Google account, with a separate sign-in for each new codespace.

Cloud machine

Codespace capabilities

The same machine under every agent. Antigravity is one way to drive it.

  • A dedicated Linux machine

    Full Linux with sudo supports installing the build dependencies.

  • VS Code in the browser

    Editor, file tree and terminal in one tab, on any device.

  • A terminal next to the agent

    The agent and development server run in separate terminals.

  • A public URL

    Every codespace has a public URL that routes a port for app access from any device.

  • Billed by the hour while it runs

    Runtime is billed by the hour. Stopping the machine stops runtime billing.

  • Snapshots to pause and resume

    Snapshots preserve the machine's state for later use and are billed monthly in credits.

First run

From launch to a public URL with Antigravity

  1. 1

    Codespace launch with Antigravity

    Codespace launch selects Antigravity, marked experimental in the launch list. It runs in the terminal only.

  2. 2

    Terminal sign-in

    The agy command in the VS Code terminal provides a Google-account sign-in link. Sign-in is required once per codespace.

  3. 3

    Task brief and public URL

    A task brief describes the change. VS Code supports review, and a running app port can be assigned a public URL.

Questions about Antigravity on Oyren

Why is Antigravity terminal only on Oyren?
Google-account sign-in takes place inside the machine and leaves no portable credential. A chat-style Agent app starting without a terminal cannot sign in, so Antigravity runs in the VS Code terminal.
Do I sign in to Antigravity every time?
Sign-in is required once per codespace. The credential lives on that machine and is not copied to a new one. A snapshot preserves the same setup for later use.
What does experimental mean for Antigravity here?
The launch list marks Antigravity experimental: the integration is newer than the others and relies on a community bridge for parts Oyren does not ship itself. In the terminal, Antigravity runs as Antigravity itself, and the machine remains available for inspection.
Can Antigravity use my Oyren credits or an API key?
No. Antigravity signs in with a Google account only. Credits and keys cover other agents on the same image, such as Qwen Code and opencode.
Can I switch to another agent on the same codespace?
Yes. Claude Code, Codex CLI, opencode, Cursor CLI and Qwen Code are also on the codespace image. Each can be started manually in the terminal with its supported sign-in or key. Oyren wires one agent at launch; the others require manual startup.
