VibeCheck - Limits Companion

Stop guessing how much AI you have left. VibeCheck shows real-time usage limits, reset times, and cost history for every AI coding tool you use -- Claude Code, Cursor, Windsurf, Codex CLI, OpenAI API, Anthropic API, Gemini CLI, and Antigravity -- all in one unified dashboard on your iPhone, iPad, and Apple Watch.

HOW IT WORKS

Your Mac runs VibeCheck in the menu bar. It collects usage data directly from each provider's API and CLI, normalizes everything into a single snapshot, and sends it to your devices over your local network. No cloud. No account. Your API keys never leave your Mac.

Pair once with a QR code, and your iPhone becomes a live dashboard for all your AI tool limits.

WHAT YOU GET

-- Unified Dashboard --
See every tool's usage percentage, requests remaining, and reset countdown in one glance. No more juggling browser tabs or terminal commands to check your limits across Claude Code, Cursor, Windsurf, and more.

-- Cost History Charts --
Track your AI spending with 30-day daily cost breakdowns. See exactly how much each provider is costing you and spot trends before they become budget surprises.

-- Usage Pace Tracking --
Reserve and deficit indicators show whether you are on track to last until your limit resets. Plan your coding sessions around your remaining capacity.

-- Provider Status Monitoring --
Know when your AI tools are experiencing outages or degraded performance before you hit a wall mid-session.

-- Threshold Alerts --
Set custom warning thresholds. Get notified before you hit your limit, not after.

-- Home Screen Widget --
A quick-glance iOS widget shows your most critical usage stats right on your Home Screen. Know your limits without even opening the app.

-- Apple Watch --
Check your AI tool limits from your wrist. Approve or deny tool permission requests directly from your Watch when Claude Code or Codex asks for approval.

-- Privacy by Design --
API keys and secrets stay on your Mac in the system Keychain. Your devices only receive normalized, signed usage snapshots over your local network. Nothing is sent to the cloud. Nothing is stored on a server.

-- Global Keyboard Shortcut --
Press Cmd+Shift+V on your Mac to instantly check all your AI limits without switching windows or opening a browser.
