See beyond a single ping.
Follow multiple targets over time, with latency, jitter, packet-loss measurements, outages, and recovery. Compare the signals instead of relying on one green light.
BUILT FOR MAC · CURRENTLY IN TESTING
Your connection
has a history.
The call froze. The game lagged. Then everything looked fine.
LagLog keeps the connection history you wish you had—right in your Mac’s menu bar. See what happened, when it happened, and what to check next.
Native macOS app. Local history. No speed tests.

A moment is easy to miss.
A history is easier to understand.
Built for the menu barMore than one targetHistory, with contextYour reports, your choice
LESS GUESSWORK. MORE CONTEXT.
Keep the details.
Make sense of the disruption.
A quick check only tells you about right now. LagLog helps you look back at the moments that matter.
Turn an incident into a useful report.
Capture a bounded incident, review what’s included, and export evidence to help a support conversation. Privacy controls let you use aliases and choose whether to include notes.
Did the change help?
Compare equal windows before and after a change. See differences alongside coverage and configuration limits—without mistaking correlation for a proven fix.
Different places. Distinct histories.
Keep connection history in the context of your named locations and network routes. Review home, work, and VPN use without treating them as the same connection.
A heads-up when normal changes.
Optional baseline alerts can flag sustained changes from a learned connection baseline. Turn them on when you want an extra signal.

A FEW THINGS TO KNOW
Clear about what
it can tell you.
Can I download LagLog today?
LagLog is currently in testing and has not been publicly released on the Mac App Store. There is no public download or sign-up available on this page. Availability will be announced here.
Is this a speed test?
No. LagLog monitors connection quality over time. It does not run bandwidth, download, or upload speed tests, inspect your browsing traffic, or log in to your router.
Does local history mean no network traffic?
No. Monitoring history is stored locally on your Mac, but connectivity checks communicate with configured network targets. DNS checks and, when needed, TCP reachability checks also generate network traffic. You choose when to export and share a report.
Will it prove that my ISP caused an outage?
No. LagLog records observations that can help narrow the investigation. Firewalls, VPNs, target behavior, and local network conditions can affect results. A missed ping alone does not prove an Internet outage or identify who is responsible.
What happens while my Mac is asleep or monitoring is paused?
Periods without observations remain gaps in the history. They are not counted as proof that your connection was working—or offline. Reports and comparisons show coverage limitations.
Which Macs will it support?
The current testing build requires macOS 26 or later. Final system requirements and release details will be confirmed when LagLog becomes publicly available.
