Load Time Tracker

Track and aggregate page-load times for selected sites, now with yearly stats.

Overview Load Time Tracker helps developers and QA teams capture every page load—across multiple tabs—then aggregates real-world load times over the last hour, day, week, month, and year. As soon as you hit refresh, you’ll see a live badge timer tick in your toolbar. Once loading completes, that final load time is recorded (with a timestamp) and included in all your sliding‑window totals. Historical data older than 365 days auto‑prunes so you keep only what matters. New: an optional on‑page overlay chip shows “Now • Last • Avg • Reloads” while you browse, and local anomaly alerts can notify you when a load spikes. Key Features - One-click tracking — Add the current domain with the “＋” button—no extra setup required. - Live badge timer — Watch your toolbar icon badge count up in real time (per tab) while the page loads. - Accurate final measurements — Uses the Performance API (with a timestamp fallback) for millisecond-precision. - Sliding-window aggregates — See total load time over the current hour, day, week, month, and year—auto‑reset as each window rolls over. - Per-site insights — Each domain card shows “Now • Last • Avg • Reloads” and a compact sparkline of the last X loads (right‑aligned with a subtle left fade). - On‑page overlay (optional) — Toggle per domain from the popup; use the global button to turn all overlays ON/OFF at once. - Anomaly alerts (optional) — Local notifications when a load is unusually slow vs a 14‑day baseline (percent/σ thresholds with cooldown). - Global totals — A “Total” line shows combined H/D/W/M/Y across your tracked sites. - Favicon scraping — Pulls each site’s real favicon (from <link rel="icon">) for easy identification. - Automatic pruning — Old logs (beyond 365 days) and stale in‑flight records are cleaned up automatically. - Lightweight & privacy‑first — All data stays local in Chrome storage. No external servers or third‑party analytics. Why You’ll Love It - Instant feedback on performance changes as you deploy or tweak code. - Live insights let you catch regressions mid-load—overlay and anomaly alerts make spikes obvious. - Rich history across multiple timeframes shows long‑term trends without manual exports. - Stay focused: everything lives in your browser, under your control. Getting Started - Install Load Time Tracker from the Chrome Web Store. - Click the toolbar icon → ＋ to begin tracking the current site. - Refresh your tracked pages—watch the live badge count and popup stats tick up. - Toggle the on‑page overlay per domain (or use the global button to toggle all). - Remove any site with the “×” to clear its data instantly.
