CodexSwitcher

A tiny native macOS menu bar app that switches the ChatGPT Codex app between your OpenAI account and DeepSeek (Flash / V4 Pro) with one click.

Features

• Menu bar dropdown: ChatGPT / DeepSeek · Flash / DeepSeek · V4 Pro
• API keys stored in macOS Keychain — never written to config.toml
• Surgical config editing: preserves your MCP servers, plugins, and project trust
• Auto-restarts ChatGPT after a switch; backs up config.toml before every change
• Includes a CLI with the same logic (codex-switcher)

Install

Download CodexSwitcher-0.1.0-macOS.zip from Releases, unzip, move to /Applications, and open.

The app is self-signed (not notarized), so on first launch right-click it and choose Open.

Use

1. Open the app and click its menu bar icon.
2. Click Set DeepSeek API Key… and paste your sk-… key.
3. Click a provider to switch.

# CLI
codex-switcher status
codex-switcher switch deepseek        # or: deepseek-pro / chatgpt
codex-switcher switch deepseek --restart
echo sk-… | codex-switcher key deepseek
codex-switcher restart

Build from source

./scripts/setup-signing.sh   # once: stable code-signing identity so Keychain keys survive rebuilds
./build.sh

Adding a provider

Add an entry to Providers.all in Sources/Providers.swift, then rebuild. Providers must speak the OpenAI Responses API (wire_api = "responses").
