Internet Health Check: Connection Monitor & Speed Test

Is your Wi-Fi down, your ISP slow, or just one site offline? Internet Health Check is an outage log + connection monitor with a free speed test — it watches your connection in the background and records every slowdown, dropout, and outage with timestamps. ONE-CLICK ANSWERS (FREE) • Free speed test: ping, download, and upload — right from the popup • Live health score: latency, uptime, dropouts, and total offline time • Outage log: a timestamped timeline of every dropout you can export to CSV • "Is it just me?" check — tells whole-network outages apart from a single site being down • Public IP display with change detection • Custom test endpoint and a latency toolbar badge • Desktop notifications the moment your connection drops or recovers DIG DEEPER WITH THE DASHBOARD • Realtime view: watch latency as it happens • History: a full timeline of outages and unstable periods • Insights: trends that show whether your connection is getting better or worse • Honest by design: periods when the browser is closed are marked as unmonitored, never faked as outages PRIVATE BY DESIGN • No account, no sign-up • No browsing history access — the extension never sees what sites you visit • Your monitoring history stays on your device in local storage • Speed tests run against Cloudflare's public speed test endpoints • Optional anonymous product analytics is off by default and never includes your browsing, monitoring, speed-test, or email content • What leaves your device, and only when you choose it: license activation, opt-in anonymous analytics, and the public-IP lookup WHY THESE PERMISSIONS? • alarms — runs background connection checks on a schedule • storage — keeps your local outage history and settings on your device • notifications — alerts you the moment the connection drops or recovers • Custom test endpoints — adding your own URL asks for access to that site only (optional host permission) No permission is used to read browsing history. Ever. FREE AND PRO Free answers "is it down right now?": speed tests, outage logging, and the "is it just me?" check are all free, with 7 days of history.
