Zero for the Codex app

June 12, 2026 · View on GitHub

How to install Zero in the Codex desktop app and keep it up to date.

Using the Codex CLI in a terminal instead? See the Codex CLI guide.

Install

The app and the CLI share one install — if you've already added Zero in the Codex CLI, it's already here too.

  1. Open Plugins in the sidebar.

  2. Click the + button in the top-right corner and choose Add marketplace.

  3. In the Source field, enter:

    officialzeroxyz/zero-plugins

    Leave Git ref and Sparse paths as they are, and click Add marketplace. You'll see a "zero-plugins marketplace added" confirmation.

  4. A Zero filter now appears next to Curated by OpenAI. Select it, then click Add plugin on the Zero plugin.

  5. Start a new chat and ask Codex: "Help me set up and test Zero." It walks you through signing in.

Staying up to date

Nothing to do — updates are automatic:

  • The Zero runner updates at the start of each session.
  • The plugin itself checks for updates once a day, in the background, and they apply the next time you start Codex.

To turn off the daily plugin check, set ZERO_PLUGIN_AUTOUPDATE=0 in your environment.
