Desktop traffic control for developers juggling Codex accounts

What it does

Codex Switcher is a Tauri-based desktop application that consolidates multiple OpenAI Codex accounts into a single interface. It lets you add, rename, and switch between accounts from the main window or system tray, while tracking 5-hour session limits, weekly usage, and manual reset credits. The app also supports automatic “warm-ups” — sending a minimal request to trigger a quota window — on a schedule or whenever a reset period hits.

The interesting bit

The warm-up scheduler is the unusual angle: you can pick specific times of day to ping all accounts, ensuring your 5-hour windows start when you want them to, not when the server decides. It also recovers gracefully from blocked switches by detecting active Codex sessions and offering to force-close them before swapping accounts.

Key highlights

• Switch accounts from the main window, native tray menu, or tray popup.
• View granular usage stats for OAuth accounts: lifetime tokens, daily buckets, streaks, and top integrations.
• Schedule timed warm-ups that run once per day and skip missed slots if the machine was asleep.
• Run fully in the menu bar on macOS, or keep a Dock icon; tray display modes include session percentage or text-only readouts.
• Serve the dashboard over HTTP for LAN or remote access via a built-in web mode.

Caveats

• macOS release builds are not Apple-notarized, so expect to clear the quarantine flag manually.
• The tool is explicitly designed only for individuals who personally own multiple accounts; credential sharing or pooling is discouraged and violates OpenAI’s terms.
• Timed warm-ups require the machine to be awake; the scheduler skips missed times rather than running them late.

Verdict

Worth downloading if you personally maintain multiple Codex accounts and want a single place to switch identities, watch quotas, and warm up windows. If you only use one account or need team-wide credential sharing, this won’t help.
