Operating system market share — 2026-09-11 to 2026-10-10

Top 25 operating systems by total pageviews.

How these figures are built

Period: April 18, 2026 to October 9, 2026. Based on 18,937,663 pageviews from 62 public websites that use BYOViral; private sites are never included. These sites are not a random sample of the web, so read the shares as a picture of this network rather than of the whole internet.

Visits from hosting and cloud networks (identified by network owner, using DB-IP ASN data) and known crawlers are labeled as bots and left out. Last updated: October 9, 2026.

Methodology

Operating systems are parsed from the User-Agent string of each incoming pageview beacon at collection time. Pageviews are aggregated daily, network-wide, across public opt-in BYOViral sites only — private sites never contribute to this dataset. Because the measurement is pageview-weighted live traffic (not a panel or a survey), heavy-browsing platforms are represented in proportion to actual usage on the network.

The network composition affects the mix: participating sites currently skew toward desktop-heavy content audiences, which lifts Windows and Linux relative to global mobile-first benchmarks.
