Codex Pacer 2.1

简体中文 · Download the latest release

A native macOS island for Codex tasks, output rate and account quota. Hover to expand, move away to collapse, or pin it open.

• See local and enabled SSH tasks, their current stage, and ended turns; click a task to open its conversation.
• See the aggregate output-rate estimate for running tasks, with tool waits handled separately from generation.
• Track short and seven-day quota, reset countdowns, pacing and the current cycle. Banked resets expiring within the current cycle appear on the curve.
• View account Credit balance and available reset credits; click the reset count to see exact expiry times, or select an expiry marker on the curve.
• Keep ended-turn cards until clicked, their state changes, or the configured retention expires; receive a reminder while the island is collapsed.
• Adjust appearance, display, reminders and privacy. Menu-bar visibility is optional. Quit from the island or settings.
• Choose Automatic, Notch or Floating on any display; browse tasks three at a time while quota stays visible.
• Use adaptive width by default, or adjust a single width with a preview and slider in Settings.
• Customize the single-line collapsed bar: choose components by category and drag their order or left/right placement, with a live preview and one Save action.
• View task TPS and observed first-output latency; spawned agents are grouped under the parent with their running count and summed TPS. Previous measurements stay visible during tools or while awaiting new data; white means updated within 15 seconds, gray means older. Updates adapt automatically to collapsed/expanded state.
• Use English or Simplified Chinese, following your Mac's language by default or selecting a language in Settings.
• Update inside the app: daily checks by default, with download and installation after you choose to install.

Requirements: macOS 14 or later, Apple Silicon or Intel. Liquid Glass requires macOS 26 or later. An authenticated Codex installation and Python 3 provide account/task data; remote sources require existing non-interactive OpenSSH access.

Install the unsigned release

The unsigned release may be blocked by macOS before the DMG opens. For a manual replacement, quit the old version first. If your installed version has Check for Updates, use it to download, verify, install and relaunch automatically.

1. Download the DMG from the latest release and double-click it first. Dismiss the macOS blocking alert.
2. Go to System Settings → Privacy & Security, scroll to Security at the bottom, find the blocked installer, and choose Open / Open Anyway. Confirm when prompted.
3. Double-click the DMG again, drag Codex Pacer into Applications, then launch it from Applications.

If macOS also blocks the app, repeat step 2 for Codex Pacer, then launch it again.

Development

Requires Xcode 26 or newer. The app has no npm or Rust dependencies.

make test TEST_FILTER='CompletionInboxTests|SessionNameTests' # during development
make build # when an app is needed for UI checks

Run the full suite once for a release candidate. Builds run in local temporary directories, reuse pinned dependency caches and print the app path. Use make release-unsigned for the unsigned universal DMG, or make release for the separate Developer ID signing/notarization workflow; no separate preview build is needed just for publication. See development and data semantics and releasing.

The maintained codebase contains only native macOS code. React/Tauri and Windows 1.x remain available in Git history and previous releases.
