In the October 2022 survey we received responses from 1,130,378,382 sites across 271,883,623 unique domains, and 12,299,940 web-facing computers. This reflects a gain of 1.13 million sites, 258,363 unique domains, and 47,769 web-facing computers.

Cloudflare saw strong growth, with an increase of 9.44 million (+11.3%) sites resulting in an increase of 0.83pp in market share. It also gained a moderate 0.20 million unique domains (+0.79%), an increase of 0.06pp in market share.

Both nginx and Apache experienced decreases across all metrics. nginx lost 10.07 million (-3.15%) sites, a loss of 0.92pp in market share, 1,201 web-facing computers (-0.16pp market share), and 20,677 unique domains (-0.03pp market share). Apache lost 1.17 million sites (-0.13pp market share), 973 web-facing computers (-0.12pp market share), and 306,055 unique domains (-0.13pp market share).

Within the top million busiest sites, Apache remains the most used web server, but its market share continues its long-term downward trend, decreasing by 0.21pp. nginx also lost 0.12pp, but closes its gap to Apache to 3,622 sites. Cloudflare’s growth continues, with a gain of 0.07pp, bringing its market share to 20.83%. This reduces Apache’s lead to less than 1pp, and Cloudflare is set to overtake both Apache and nginx in the next few months if the trends continue.

OpenResty had the largest increase in web-facing computers, gaining 13,972 (+7.69%). However, it was overtaken by Cloudflare in overall number of sites after a decrease of 1.06 million (-1.14%) sites. It also saw a decrease of 0.26 million (-0.65%) unique domains, losing 0.11pp in market share.

In the September 2022 survey we received responses from 1,129,251,133 sites across 271,625,260 unique domains, and 12,252,171 web-facing computers. This month all three metrics have decreased since August, with a loss of 5.82 million sites, 115,512 unique domains and 113,356 web-facing computers.

nginx had the largest increase in web-facing computers, gaining 28,887 (+0.56%) this month. OpenResty had the second largest increase, gaining 6,008 (+3.54%) web-facing computers, along with a gain of 339,813 (+0.86%) domains and 149,893 (+2.35%) active sites. Google showed strong growth in all metrics, with an increase of 5,127 web-facing computers, 211,135 (+8.83%) domains, and 895,225 (+4.71%) active sites.

Within the top million busiest sites, Apache lost 0.21pp of its market share. Despite this, it continues to be the most commonly used web server in the top million. nginx also continued its long-term downward trend, but lost only 0.14pp, further closing the gap between Apache and nginx. The gap now stands at 4,499 sites, a decrease of 13.8% since last month. Meanwhile, Cloudflare’s growth continues, with its market share in the top million increasing by 0.25pp.

Apache also experienced a loss in overall market share, losing 414,684 (-0.94%) active sites and 18,156 computers (-0.49%). The only other developers to lose active sites were Microsoft and nginx, with losses of 58,443 (-1.01%) and (-0.10%) respectively.

In the August 2022 survey we received responses from 1,135,075,578 sites across 271,740,771 unique domains and 12,365,527 web-facing computers. This reflects a loss of 4.4 million sites, but a gain of 12,212 domains and 24,355 computers.

OpenResty saw the most significant change in web-facing computers, with a gain of 10,138 (6.1%). Furthermore, 2.8 million (3.1%) extra sites were seen since July, with a small loss of 466,322 domains (1.2%). This continues the trend of OpenResty’s fast growth in web-facing computers (46% since August 2021) while the number of domains and sites has not grown in tandem, remaining roughly static over the period.

nginx continues to be the most commonly used web server and saw modest gains of 25,053 domains (0.03%) and 13,481 computers (0.3%). However, we experienced a significant reduction in the number of nginx-hosted sites responding to our requests this month, with a loss of over 15 million. This represents around 4% of sites hosted using nginx in July.

Continuing the trend of strong growth over the past two months, Cloudflare gained an additional 4.4 million sites (6%) and 1.1 million domains (4.7%). This gives Cloudflare a total market share of 6.8% of sites and 9% of domains, an increase of 0.4pp on both metrics since July. Cloudflare also had the strongest growth amongst the top million busiest sites, gaining 0.25pp, thereby holding a 20.51% market share.

Apache’s position as the most commonly used web server for the top million busiest sites continues to erode, with a loss of 0.19pp this month. nginx continues to gain market share, up 0.07pp. If this trend continues, nginx will overtake Apache in the short term, and in the long term, Cloudflare will overtake both of its rivals.

In the July 2022 survey we received responses from 1,139,467,659 sites across 271,728,559 unique domains and 12,341,172 web-facing computers. This reflects a loss of 7.5 million sites and 1.3 million domains, but a gain of 116,386 computers.

Cloudflare continues its trend of strong growth across the sites and domains metrics this month, increasing by 5.8 million (8.6%) and 259,000 (1.24%), around double that of last month. This gives Cloudflare a total market share of 6.4% share of sites and 8.6% domains, increases of 0.5pp and 0.1pp compared to June.

Whilst still being the most popular vendor across the sites, domains and web-facing computers metric, nginx takes a loss of 4.99 million sites (1.43%), 775,000 domains (1.02%) and 3,400 computers (0.1%) this month. Apache also saw losses, dropping by 1.28 million sites (0.49%) and 379,000 domains (0.61%), however experienced the largest gain in web-facing computers of almost 22,000 (0.6%).

Apache continues to hold on to the top spot in the market share of the top million busiest sites with 22.33%, with nginx in close second at 21.55%. Both however have seen decreases in market share of 0.22pp and 0.1pp respectively, with Cloudflare increasing by 0.08pp to 20.26%. If this trend continues, we should expect to see Cloudflare overtake its rivals within the next year.

OpenResty saw its most significant change over the last 4 months with a decrease of 2.9 million sites (3.21%) and 354,000 domains (0.87%). Conversely, it experienced a significant gain of 17,700 web-facing computers (12.0%).

Lightspeed saw strong growth this month with an increase of 745,000 sites (1.4%), 88,000 domains (1.1%) and 4,500 computers (3.3%).

In the June 2022 survey we received responses from 1,146,976,964 sites across 273,010,403 unique domains and 12,224,786 web-facing computers. This reflects a loss of 8.75 million sites and 583,000 domains, but a gain of 155,000 computers.

Cloudflare experienced strong growth this month, gaining 2.99 million sites and 85,000 domains, representing a 4.64% growth in its number of sites. Cloudflare experienced a significant outage on 21 June, impacting around half of the total requests made to its network. The outage lasted around an hour and a half and affected a significant number of popular sites. 20.2% of the million most visited sites rely on Cloudflare (up 1,400 sites since last month).

The three largest vendors by the million most visited sites metric—Apache, nginx, and Cloudflare—all have similar market share, though only Cloudflare gained market share this month. Apache saw the largest loss, dropping 2,190 sites (-0.96%), while nginx lost 280 sites (-0.13%).

LiteSpeed gained a significant number of sites with an addition of 2.96 million (+5.89%), and gained 171,000 (+2.21%) domains - the second largest increase this month. The number of web-facing computers using LiteSpeed also showed strong growth, increasing by 4,460 (+3.44%) to a total of 134,000.

nginx and Apache remain the two largest server vendors, though both saw similar losses of 6.52 million (-1.84%) and 6.18 million (-2.33%) sites this month. Despite this, nginx gained 795,000 (+1.06%) domains and saw continued growth in the number of web-facing computers with 158,000 (+3.44%) computers. Conversely, Apache lost 1.07 million domains (-1.71%) and 25,700 (-0.74%) web-facing computers.

In the May 2022 survey we received responses from 1,155,729,496 sites across 273,593,762 unique domains and 12,069,814 web-facing computers. This reflects a loss of 5.23 million sites but a gain of 1.63 million domains and 95,200 computers.

nginx gained the largest number of domains (+1.24 million) and also a hefty amount of web-facing computers (+21,500), further securing its lead in both metrics. The total number of domains powered by nginx is now 75.0 million (+1.68%) and its market share has increased to 27.4% (+0.29). In terms of web-facing computers, nginx now has a total of 4.60 million; and although its leading market share fell slightly to 38.1%, Apache’s fell slightly further, extending the gap between the two to 9.54 percentage points.

nginx also continues to lead with a 30.7% share of all sites, despite losing the largest amount this month (-6.57 million). Apache follows with a share of 23.0%, but also lost a large number of sites (-2.32 million). The largest gain in this metric was seen by Google, which added 2.96 million sites to its total and increased its market share to 4.14%. LiteSpeed made the second largest gain of 1.26 million sites, and stays slightly ahead of Google with a share of 4.35%.

Google and LiteSpeed also made the only significant gains in the active sites metric, with Google gaining 977,000 and LiteSpeed gaining 151,000. Google has a greater lead in this metric, with a market share of 9.49% versus LiteSpeed’s 4.60%.

Cloudflare is continuing to edge its way up towards the leaders in the top million websites. This month it gained an additional 1,822 sites and now accounts for more than 20% of the top million sites for the first time. Meanwhile, both Apache and nginx lost more than a thousand sites each in the top million, making it look ever more likely that Cloudflare could gain places by the end of the year. Apache, nginx and Cloudflare currently have top-million site shares of 22.8%, 21.7% and 20.0% respectively.

One surprise this month was that the largest computer growth was seen not by nginx, but by the awselb (Amazon Web Services Elastic Load Balancing) web server, which gained 26,200 computers to reach a total of 378,000. These computers are likely to form only a small fraction of the AWS infrastructure used by the 1.86 million sites that are served from these computers, as AWS ELB achieves fault tolerance and scalability by automatically distributing incoming application traffic across multiple targets, and can also spread traffic across multiple AWS Availability Zones.
