CCS Bar — Native macOS Menu Bar App

CCS Bar is a native macOS menu-bar app that shows live subscription quota and usage at a glance for your Claude Code, Codex, and CLIProxy accounts, without opening the dashboard.

What It Is

CCS Bar is a thin client of the CCS local web-server. It never talks to a provider directly: every call goes to localhost, and CCS performs any provider fetch server-side. Opening the menu fires a debounced force-refresh so the glance reflects live data without blocking the UI.

It is macOS only.

What It Shows

• Per-account quota percent and reset countdown
• Account tier
• Today, 7-day, and 30-day cost
• A 30-day usage sparkline
• Account state (active, paused, default)
• Native subscription rows for Claude Code and Codex

Requirements

• macOS
• CCS CLI installed and configured (ccs config works)
• The CCS web-server reachable on loopback. ccs bar (or ccs bar launch) starts it for you.

Install

ccs bar install

This downloads CCS-Bar.app.zip from the floating ccs-bar-latest GitHub release and installs CCS Bar.app into ~/Applications. Downloads are restricted to github.com and objects.githubusercontent.com, and extraction is guarded against zip-slip.

After installation, CCS reads the app version directly from the bundle's Info.plist and pins it to ~/.ccs/bar/.version. It then performs a reachability check against the bar API (GET /api/bar/summary). A 404 response means the running CCS server predates CCS Bar support — update CCS to a version that includes CCS Bar, then restart ccs bar.

Gatekeeper note

The v1 builds use ad-hoc signing, so the first launch may be blocked by Gatekeeper. Either right-click the app and choose Open, or clear the quarantine attribute:

xattr -dr com.apple.quarantine "$HOME/Applications/CCS Bar.app"

Launch

ccs bar          # alias: ccs bar launch

This checks whether a CCS web-server is already running (probing port 3000, 3001, 3002, 8000, and 8080, with the port from the previous bar.json checked first). If a live server is found it is reused; otherwise a new one is started. Either way the discovery file ~/.ccs/bar.json is written and the app is opened. The discovery file looks like this:

{ "baseUrl": "http://127.0.0.1:3000", "port": 3000, "authMode": "loopback" }

The Swift app reads ~/.ccs/bar.json to find the server.

Loopback / Localhost Requirement

CCS Bar talks only to http://127.0.0.1:<port>. v1 supports authMode: "loopback" only, meaning dashboard auth disabled on localhost.

If you bind the dashboard beyond localhost (for example --host set to a non-loopback address) with dashboard auth disabled, the bar's read endpoints (GET /api/bar/summary, GET /api/bar/analytics) are refused for non-loopback callers, and the app cannot reach the server. Keep the dashboard on loopback for CCS Bar to work.

Uninstall

ccs bar uninstall

This removes ~/Applications/CCS Bar.app and the installed version pin. It is a no-op if the app is not present.

Troubleshooting

• Install fails with "server predates CCS Bar" or bar API returns 404: the CCS server running does not yet include CCS Bar. Update CCS (npm i -g ccs@latest or equivalent), then restart ccs bar.
• Server failed to start: ccs bar first checks whether a CCS server is already running on the candidate ports (3000, 3001, 3002, 8000, 8080) and reuses it if found. A true failure here means a non-CCS process is occupying all candidate ports. Free one of those ports and re-run ccs bar.
• App won't open (Gatekeeper): right-click and Open, or clear quarantine with the xattr command above.
• Blank app: the web-server is not running. Re-run ccs bar and confirm ~/.ccs/bar.json exists.
• Quota not updating: re-open the menu to force a refresh, or confirm the server is still reachable on loopback.

Development

The source lives in macos-bar/. Contributors can build and run the logic checks with a Swift 5.9+ toolchain (CommandLineTools is enough, full Xcode not required):

swift build                 # build all targets, including the app
swift run ccs-bar-check     # run the logic tests
