February 2023 Web Server Survey

In the February 2023 survey we received responses from 1,127,630,293 sites across 270,727,775 unique domains, and 12,142,793 web-facing computers. This reflects a loss of 4,638,508 sites, 240,148 domains and 13,907 computers.

OpenResty had the largest percentage growth in sites this month: it is now used by 95,176,082 sites, an increase of 2,884,258 (+3.13%) since last month. This brings its share of sites to 8.44%, up from 8.15% (+0.29pp). OpenResty’s market share by domain count remained stable, with a slight 0.01pp increase this month – its small loss of 14,039 domains was counteracted by the greater loss of domains across all vendors this month.

Cloudflare continues to grow, gaining 1,669,867 sites (+1.49%) and 500,432 domains (+1.89%) since our January survey. Following Cloudflare becoming the most commonly used web server vendor within the top million sites last month, it has started to cement its position: gaining 672 sites (+0.31%) of the top million sites this month, giving it a 21.71% market share (+0.07pp).

Meanwhile, Apache lost 626 sites (-0.29%) in the top million sites, bringing its share to 21.34% (-0.06pp). Outside of the top million, Apache saw more significant losses, netting a decrease of 2,593,754 sites (-1.11%) and 434,071 domains (-0.74%).

Similarly to Apache, nginx lost a significant number of domains this month, being down by 483,620 domains since our January survey (-0.66%). However, nginx maintained its overall site count and even gained 219 of the top million busiest sites, giving it a 21.23% share (+0.02pp) within the top million sites.

The largest loss in sites for a major vendor this month comes from Microsoft, which is down 2,866,173 sites (-9.59%) and 74,094 domains (-0.98%). This continues its consistent downwards trend since December 2018.
