RUM Insights PREVIEW TEST
Introduction
This page captures a collection of basic visualizations for the data contained in the RUM Archive. It's goal is to allow users to get a feel for the most important insights that can be gained from the data, without having to execute SQL queries themselves.
Note that we intentionally do not include interpretations of the data here, as this can often be quite nuanced. For that, look at our regular blog posts that discuss RUM Insights in depth.
Baseline Support
The Web Platform Baseline project aims to track when exactly Web features became available in all major browsers (Chrome, Edge, Firefox, Safari). This is important since not all browsers implement all features at the same time; using cutting edge feature X on browser A might mean you leave some of your users on browser B out in the cold (or having to implement a costly fallback).
However, you also don't want to only use features from Baseline 2017, "just to be safe", because that would mean missing out on many already widely available features. In practice, you want to utilize features that almost all of your users will benefit from. To help you figure out which features those are and which Baseline year you should target, below we show how many global visitors observed by the RUM Archive on the first Tuesday of April 2024 had support for ALL the features in a particular Baseline year.
