I built a menu bar utility to monitor VPN status and detect leaks on macOS.
The problem: macOS doesn't make it obvious when your VPN silently disconnects, and even when connected, DNS or IPv6 traffic can leak outside the tunnel without you knowing.
VPN Peek shows your connection status at a glance and runs leak detection:
- DNS leak detection: checks if your DNS queries go through your VPN or leak to your ISP
- IPv6 leak detection: detects if your real IPv6 address is exposed
- Shows current public IP and location
- Notifications when VPN drops or leaks are detected
- Auto-refreshes on network changes
Works with any VPN provider – it monitors at the system level, not tied to any specific app.
Built with SwiftUI/AppKit hybrid for native macOS feel. Runs locally, only reaches out to check your public IP for leak detection.
$3.99 on Mac App Store, no subscription.
Feedback welcome – especially from anyone who's dealt with VPN leak issues.
