Load Time Tracker

About

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.
