sitespeed.io: The Browser That Keeps the Whole Timeline

web-performance-testing.com ↗ · Developer Corner · score 86.0
○Open: public page gives enough substance to understand the site $Paid: pricing, booking, ecommerce, subscription, or paid access is visible ADAds: visible ad load or ad-supported content ✦Pretty: notable design, copy, craft, or presentation ◆Pro: polished, finished-feeling, serious, or operationally mature ◇Niche: specific audience, workflow, or unusually focused use case ◉Human: personal, local, community, civic, handmade, or real-person signal !Suspicious: scammy, spammy, trust theater, finance fog, or credibility concern

An open-source web-performance tool that drives real browsers, records detailed loading behavior, and produces HTML reports, waterfalls, videos, and Core Web Vitals.

Why it surfaced

sitespeed.io treats a page load as a sequence rather than a single score: it recommends multiple runs, reading the median, and inspecting where DNS, connection, rendering, and third-party requests introduce noise. It runs through npm or Docker, supports Firefox, Chrome, Edge, and Safari, and can send metrics to Graphite or InfluxDB for Grafana dashboards and CI budgets.
