Always-visible latency
Compact millisecond values stay in the menu bar, colour-coded green, amber, or red using global or per-resolver thresholds.
macOS Menu Bar Utility
DNS performance, always in view
Watch live, colour-coded latency for every resolver in the menu bar, then left-click for fast, dig-like DNS lookups over classic UDP or DNS-over-HTTPS.
Features
Answers at a glance, details on demand
Built for people who care which resolver is fast, which is failing, and what DNS actually returned.
Quick DNS lookup
Enter a domain, URL, or IP and get structured A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, PTR, and SRV results with TTLs.
UDP & DNS-over-HTTPS
Measure classic DNS on UDP port 53 and standards-compliant wire-format DoH side by side, including real connection overhead.
Live history
See a 15-minute hover graph, then open Detail for current, average, p95, peak, jitter, and loss across ranges up to 7 days.
Honest measurement
A monotonic clock measures real round trips. Timeouts become real loss, never invented latency, and answers must match the exact question.
Private by design
No account, cloud service, analytics, advertising, cookies, or tracking. Configuration stays in macOS user defaults on your Mac.
Your DNS queries go only where you choose
Monitoring sends the configured question only to the resolvers you add. Quick Lookup strips a pasted URL down to its host and sends only that host and the selected record types — never the path, query string, fragment, or credentials.
Resolver configuration and preferences stay in macOS user defaults. Nothing is sent to slepp.ca, dnsbin.ca, or any developer endpoint, and the privacy manifest declares Data Not Collected. Read the full privacy policy.
