Codex CLI Launcher

Codex CLI Launcher is an unofficial VS Code extension that opens OpenAI Codex CLI in a new side terminal directly from the editor toolbar.
Works on Windows, macOS, and Linux where Codex CLI is available to the integrated terminal.

Features
- Adds a launcher button to the editor title area
- Uses local Marketplace and toolbar artwork packaged with the extension
- Opens a fresh terminal beside the active editor on every launch
- Uses the active editor workspace when available, with a fallback to the first open workspace folder
- Runs a configurable Codex CLI command
- Offers guided installation when the default
codex command is not available
- Supports quoted Windows executable paths
- Does not collect telemetry, analytics, or personal data
Requirements
- VS Code
^1.86.0
- Codex CLI available in the integrated terminal environment, or a working custom launch command configured in settings
Installation
- Install the extension from the VS Code Marketplace.
- Install Codex CLI globally:
npm install -g @openai/codex
- Open any file in VS Code.
- Click the launcher button in the editor title.
Any equivalent install or launch method that makes codex available in your terminal also works.
Guided Installation
If the default codex command is missing, the extension shows a guided warning with options to install Codex CLI, open the Codex documentation, or open the extension settings.
Choosing Install opens a visible terminal and runs a generated prompt script. Installation only starts after explicit confirmation:
Codex CLI was not found.
Install Codex CLI now? (y/N):
Answer y or yes to run:
npm install -g @openai/codex
Any other answer cancels installation. Restart VS Code if your shell needs a new environment to see globally installed npm commands.
How It Works
Each launch creates a new terminal beside the current editor and sends the configured command immediately. Existing terminals are not reused.
When possible, the launcher opens the terminal in the workspace folder of the active editor. If the active editor is outside the workspace, it falls back to the first workspace folder in the current VS Code window.
The launcher checks command availability when the terminal runs, so it behaves consistently with your normal integrated terminal environment.
Configuration

Examples:
Default command:
"codexCliLauncher.cliCommand": "codex"
Launch through npx:
"codexCliLauncher.cliCommand": "npx --yes @openai/codex"
Windows executable path with spaces:
"codexCliLauncher.cliCommand": "\"C:\\Users\\You\\AppData\\Roaming\\npm\\codex.cmd\""
Troubleshooting
The terminal opens but codex is not recognized
Install Codex CLI globally and confirm that codex works in a regular integrated terminal:
npm install -g @openai/codex
If your setup relies on shell initialization, restart VS Code after installation so new terminals inherit the updated environment.
Check codexCliLauncher.cliCommand and verify that the same command works in a regular terminal.
Custom executable path on Windows
Quote executable paths that contain spaces. This is required for commands such as "C:\Users\You\AppData\Roaming\npm\codex.cmd".
Multi-root workspaces
The launcher prefers the workspace folder of the active editor. To control where Codex starts in a multi-root window, open a file from the target workspace before clicking the toolbar button.
Privacy
Codex CLI Launcher does not collect telemetry, analytics, or personal data.
All extension artwork is packaged locally in the VSIX. No external image assets are loaded at runtime.
Development
Local verification and packaging:
npm install
npm run check
npm run test:integration
npm run package
npm run package creates the .vsix file in the workspace root.
The repository includes unit tests, metadata checks, VS Code integration smoke tests, and CI coverage for Windows and Linux.
