Is it the Wi‑Fi,
or the internet?
straylight measures latency, jitter and packet loss to your router and to the internet side by side, so the menu bar answers the question before a call starts stuttering. It keeps a week of per-minute history, with outages logged and exportable for your ISP.
WHAT IT SHOWS
ROUTER AND INTERNET
Your router and two internet hosts from different providers, measured together, with a plain verdict: Good, Internet problem, Internet down, Local network problem or Offline.
LATENCY, JITTER, LOSS
The latest reply, median and p95, jitter and loss for each target, with a 60-second trace where a lost ping drops the line flat. Wi‑Fi signal and noise alongside.
HISTORY
Per-minute stats for 7 days and hourly for up to 90, outages and spikes logged, sleep and pauses marked as gaps. Export it as CSV to show your ISP.
NETWORK TRAFFIC
straylight sends small ping packets (56 bytes) to the targets you choose: your router, 1.1.1.1 and 8.8.8.8 by default, plus 1.1.1.1 over IPv6 on networks that have it. That's one per target per second on power and one every 5 seconds on battery. It stops while the screen is locked unless you turn on overnight monitoring. If a network blocks ping, it times a normal HTTPS connection instead.
The only other request is a daily update check to this site. There's no telemetry, and history stays on your Mac unless you export it.
