Internet Health
See whether the connection is Excellent, Good, Slow, Unstable, Offline, or waiting for network sign-in — with current latency, jitter, and recent failures.
Onlink for Mac · v1.2
Know when your internet is unreliable — and why.
Onlink quietly measures connection health, remembers the bad moments, and turns them into useful evidence — without turning your Mac into a speed-test machine.

Reliability, not one number
See how your connection behaves over time.
A fast speed test can still hide an unreliable connection. Onlink watches lightweight health signals so you can see latency, jitter, failed checks, incidents, and measured reliability together.
Reliability Today
Onlink’s 0–100 score combines measured uptime, incidents, latency, jitter, and failed checks while staying honest when there is not enough data yet.
History that has context
Keep outages and instability alongside the measurements around them, instead of trying to remember later whether the problem was Wi-Fi, the router, DNS, or the wider internet.

Keep the evidence around the incident.
Onlink can capture lightweight diagnostic evidence around an outage or unstable period, then explain the likely cause in plain language without claiming more certainty than the measurements support.
- BeforeWhat the connection looked like before the incident.
- DuringWhat failed or degraded while it was happening.
- AfterRecovery evidence once the connection comes back.
- Likely causeWi-Fi, router/local network, DNS, ISP/internet, sign-in, or unclear.

Useful after the problem is over
Turn “the internet was bad” into something you can show.
Run a lightweight diagnosis when you need one, let saved history surface recurring patterns, and turn the measurements into an ISP-ready snapshot. The optional menu-bar companion keeps the current state close without replacing the full app.

Local first
Your connection history stays on your Mac.
Onlink does not need an account or an Onlink backend. Historical insights are calculated locally, and no AI or cloud analysis is used to decide what your connection evidence means.
How Onlink handles network data →Free & Pro
Try the real tools before deciding.
Free includes core Internet Health, Reliability Today, 24-hour history, and monthly access to Diagnose, speed tests, and single-incident reports. Pro adds longer history, deeper trends and recurring-pattern analysis, and removes those monthly usage limits.
Free24-hour history · 3 speed tests, diagnoses, and reports per calendar month
Pro7 / 30 / 90-day history · deeper reliability analysis · unlimited quota features
Onlink 1.2
v1.2 adds automatic incident diagnosis, Incident Detail evidence, Internet Reliability Score, recurring insights, and stronger ISP-ready reporting.
Onlink for macOS
Know what happened the next time your internet acts up.
Keep lightweight reliability history running in the background, then inspect the evidence when you actually need it.
