Four apps, live now

Two in the Mac menu bar, two on iPhone — all fully sandboxed.

AI-Cockpit

Every AI budget in one place.

Claude subscription usage — 5-hour and weekly windows, with forecasts
Two Claude accounts side by side — personal and work, each on its own named card
ChatGPT/Codex quotas, OpenAI and Anthropic API costs, Kimi credit, OpenRouter credits, Grok balance — plus GitHub Copilot usage, coming with 6.5 (in App Store review)
Live Claude Code sessions with subagents, token shares and context windows
Alerts at 75% and 90% — before the window closes on you
Drag the cards into the order you want, and pick which figures the menu bar shows
Every card marked with its own coloured letter — C for Claude, C2 for a second Claude account, G for ChatGPT, O and A for the APIs, K for Kimi, R for OpenRouter, X for Grok, GC for GitHub Copilot, S for sessions

How I build

At rest

AI-Cockpit's API keys and sign-ins live only in the macOS Keychain — encrypted by the OS, tied to this device, never synced to iCloud. BarBox and Baumängel Tracker store no credentials at all — there is nothing to keep, so nothing sensitive ever touches a settings file, a database or a log.

In transit

AI-Cockpit and BarBox connect over HTTPS to a fixed, published allowlist of hosts — nothing else, redirects never followed. Baumängel Tracker makes no network connection at all. Every host is named in each app's privacy notes; check for yourself rather than trusting a summary.

Yours to keep

Usage history exports as HTML or CSV whenever you want, and clears just as easily from Settings. Nothing sits behind a login only I control — it's your file.

Checked, not assumed

AI-Cockpit was reviewed against OWASP ASVS 4.0, OWASP MASVS, the Apple Secure Coding Guide, RFC 8252/7636 and the CWE Top 25.

Native, not wrapped

Swift and SwiftUI throughout. No Electron, no bundled browser, no 300 MB for a menu bar icon. All three apps ship through the App Store, fully sandboxed.

Open where it can be

BarBox (GPL-3.0) and Baumängel Tracker (MIT) are open source — so you don't have to take my word for any of this: the network code is public. Build it yourself with swift build -c release. AI-Cockpit is proprietary, but its documentation is public.
