Download for Mac — Apple Silicon · Download for Windows — x64
Free and open source. Mac download: 3 MB. Windows download: 2 MB.
Early preview: I've tested it on my Mac with procode.ghe.com.
Windows builds and tests pass, but I haven't tried it on a Windows machine yet.
Both downloads are unsigned, and the Mac app isn't notarized.
It relies on an internal GitHub endpoint that could change; other hosts and
plans haven't been verified.
- See remaining credits, allowance, usage, and your next reset date.
- Refreshes every ten minutes, or whenever you choose Refresh now .

It's about 500 lines of Rust, including tests, with no frontend JavaScript or webview window. The numbers are your monthly account balance, not usage for one terminal session. AI credits aren't the same as a count of premium requests.
1. Install GitHub CLI and sign in for your account's host, if you haven't already:
gh auth login --hostname YOUR_HOST
Replace YOUR_HOST with your GitHub hostname, such as procode.ghe.com.
2. Grab the download for your computer using the links above.
| Platform | Install | Find Afterglow |
|---|---|---|
| macOS 11+, Apple Silicon | Open the DMG; drag Afterglow to Applications | Ring and percentage in the menu bar |
| Windows 10/11, x64 | Run the installer; launch from Start | Right-click the tray ring, possibly under hidden icons |
These previews may trigger Gatekeeper or SmartScreen warnings. Only approve the app if you trust the download and your organization's policy allows it. Don't disable system protections. Help with installation.
3. Set your host if needed. The default is procode.ghe.com.
Choose Open settings file… from the ring's menu, edit the hostname value,
save, and choose Refresh now. Your gh login must match that host.
Windows shows the percentage inside the menu, not beside the tray icon.

It doesn't have burn-rate estimates, a model breakdown, notifications, or launch-at-login yet. GitHub's figures can take a while to catch up, so the menu shows when the API reported them and when the app last checked.
