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.
Current release: 0.1.7.

✨ Want one launcher for every agent? Try Super CLI — a single sidebar that launches Claude Code, Codex, Copilot, Cursor, Grok, Kilo, Antigravity, OpenCode, and more. Install this launcher for Codex alone, or Super CLI for the whole set.
Features
- Adds a launcher button to the editor title area
- Uses local Marketplace and toolbar artwork packaged with the extension

- Uses the active editor workspace when available, with a fallback to the first open workspace folder
- Runs a configurable Codex CLI command
- Links to the official Codex CLI installation documentation when the default
codex command is not available
- Supports quoted Windows executable paths
- Does not collect telemetry, analytics, or personal data
Requirements
- VS Code
^1.103.0
- 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 by following the official Codex CLI installation documentation.
- 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.
Missing CLI
If the default codex command is missing, the extension offers to open the official Codex CLI installation documentation in your browser. The extension does not download installers, create installation scripts, or run package-manager installation 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
| Setting |
Default |
Description |
codexCliLauncher.cliCommand |
codex |
Command executed when the launcher button is clicked. The command is sent directly to the integrated terminal. |

Use the Command Palette to open the extension settings:
Codex CLI Launcher: Open Settings
Examples:
Default command:
"codexCliLauncher.cliCommand": "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
Follow the official Codex CLI installation documentation, then confirm that codex works in a regular integrated terminal.
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.
