Sub2API gateway subscription → Codex CLI / Codex App injector. macOS-native, zero-deps Python single-file. Supports codex2api.com and any self-hosted Sub2API instance.
sub2cli is a macOS application that helps people manage their Codex AI assistant connections. It provides a visual dashboard where users can add multiple relay services (third-party API providers) and official Codex accounts, test which endpoints work best, view account balances and usage, and automatically configure Codex to use their preferred setup. The app handles the technical details of switching between different services and accounts, creates automatic backups before making changes, and can be used either through a desktop interface or a terminal-based control panel.
How It Works
You've been using Codex but switching between different services and accounts feels complicated. You discover sub2cli, a tool that promises to make managing everything in one place.
You download the app and drag it to your Applications folder. The app walks you through getting started with a friendly interface.
You add your favorite third-party service (or Codex's official service) by entering your account details. The app saves your login information securely in your Mac's password manager.
With one click, you see which servers respond quickest. You can even test different pricing groups to find the best deal for your needs.
You select the relay, endpoint, and pricing group that work best for you. The app shows you exactly what will change before anything is modified.
The app sets up Codex for you - updating all the necessary settings and files. It creates a backup first, so you can always undo if something goes wrong.
Your Codex assistant is now connected to your chosen service. Switching between different accounts or relays is as easy as clicking a button.
