About
Core Web Vitals History is a web tool that fetches historical Core Web Vitals data for a given URL from Google’s CrUX History API. It shows the last 6 months of available data and does not capture or store metrics itself.
The tool is intended for developers and web performance teams that need to identify when a regression or improvement occurred and correlate it with code, infrastructure, or other site changes. It is limited by Google’s aggregation thresholds, so some low-traffic URLs may not have data available.
- Historical Core Web Vitals for a URL

Free Tier Value
This free tier is perpetual and uncapped, so it’s treated as an always-available public tool rather than a metered plan. Since it provides access to historical Core Web Vitals data for any URL with no stated limits or paid upgrade path on the page, the practical monthly value is not defensibly bounded in dollar terms.
