Internet Health Check: Connection Monitor & Speed Test

Monitor your internet in real time: free speed test, outage log, latency & ping tracking, and reports to prove it's not on your end.

Is it your Wi-Fi, your ISP, or just one slow website? Internet Health Check answers that question in one click — and keeps the receipts. It quietly monitors your connection in the background, scores its health in real time, and records every slowdown, dropout, and outage so you can see exactly when your internet failed and for how long. Perfect evidence for that next call with your ISP. WHAT YOU GET FREE • One-click speed test: ping, download, and upload • Health score with live latency, uptime, dropouts, and total offline time • Outage log with a full timeline 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 • All monitoring data stays on your device in local storage • Speed tests run against Cloudflare's public speed test endpoints FREE AND PRO The free plan covers everyday monitoring — speed tests, outage logging, and the "is it just me?" check are all free. Pro is built for proof and power users: the ISP Evidence Report (a polished outage timeline plus your measured speed vs. your advertised plan), automatic scheduled speed tests with trends, gaming/call session diagnostics (jitter and packet loss), extended history, smart insights, and advanced charts. Every Pro feature is free for 7 days — no card required. WHO IT'S FOR Remote workers who need to prove "it's not on my end", gamers and video callers hunting lag spikes, anyone with flaky home internet, and IT folks who want a lightweight connection monitor in the browser. Install it, open the popup, and know in seconds whether your internet is healthy, slow, or down. Questions or feedback: https://internethealthcheck.anhbui.dev/support
