Frequently Asked Questions

Is this processed locally?

Yes. Data comes from the browser Network Information API.

Why are some fields unavailable?

The Network Information API is not supported in all browsers. Safari and some mobile browsers may omit details.

What is effectiveType?

A rough classification: 4g, 3g, 2g, or slow-2g based on downlink and rtt estimates.

About Network Info Display

The browser's Network Information API exposes a few attributes about your connection — type (wifi, cellular), effective tier (slow-2g, 2g, 3g, 4g), and downlink estimate. This page shows those values live so you can debug responsive loading strategies.

What Each Field Means

effectiveType is a coarse bucket — 'slow-2g', '2g', '3g', or '4g'. It is not a measurement; it is the browser's classification based on recent traffic. downlink is an estimated maximum throughput in Mbps. rtt is round-trip time in milliseconds. saveData is

when the user has enabled data saver mode in their browser or OS — respect it by serving smaller images or disabling autoplay." }} />
