Biggest Movers
Expert Insight: Web Servers Market Share & Momentum
Three servers hold about 89% of the web, and almost the only thing that moves is hosts reconfiguring.
Apache runs on about 5.1M of the 13.9M domains where we can read a server header, roughly 37%. Nginx is on about 4.7M and LiteSpeed on 2.4M, so the three together are close to 89%. The largest 30-day gain anywhere in the category is Nginx, at under a thousand domains. Everything else that moves in this table moves because an operator changed a configuration, not because a site changed software.
A three-way split, and one of them is really the second
Apache about 37%, Nginx about 34%, LiteSpeed about 18%. OpenResty at roughly 7% is an Nginx distribution rather than a separate server, so the Nginx family is closer to 41% of the category and is the largest thing here. IIS is at 3% and everything below it is under half a percent. The long tail of 68 entries adds almost nothing.
Nothing in this category grows
The biggest 30-day gain is Nginx at about 900 domains on a base of 4.7M. Second is Angie, an Nginx fork, in the hundreds. That is the whole growth story. Over the longer window the two leaders both rise, Apache by roughly 122,000 and Nginx by about 100,000, which tells you the 30-day dips are turnover rather than direction.
The 4.4% turnover is hosting operations, not migrations
OpenResty lost about 121,000 domains over 30 days, roughly 13% of its base, and LiteSpeed about 114,000, close to 5%. No fleet of sites reinstalls its web server in a month. What changes is what the header says, and a host that reconfigures a proxy layer or upgrades a control panel moves tens of thousands of domains at once. Read big swings here as one operator making one change.
The measurement is unusually honest, with one blind spot
Every entry here is matched on the Server response header, which the origin sends on every request and which changes the moment configuration changes. There are no verification records in this category and nothing that outlives the software it describes, so both the counts and the turnover mean what they appear to mean. The blind spot is deliberate suppression: an operator can strip or rewrite the header, and a CDN in front of the origin often reports itself instead, so absence from this table is not evidence a server is unused.

FAQ.
What is Web Servers software?
Web Servers covers the tools a site can load or configure to handle this part of its stack. We detect one of the 68 web servers tools in this category on 13,859,021 live sites. A detection means we found the technology on the site, which is not the same as a paid account.
What are the most popular web servers platforms?
Across 13,859,021 detected sites, the most widely found web servers tools are: Apache HTTP Server (37.12% share, 5,144,649 sites), Nginx (33.97% share, 4,708,036 sites), LiteSpeed (17.62% share, 2,442,625 sites). Others we see regularly include OpenResty and IIS.
Which web servers tool has the largest market share?
Apache HTTP Server is the most widely detected web servers tool at 37.12% share, on 5,144,649 sites. The largest share of those sites belongs to various companies, and to businesses in the 1-10 employee band.
Which industries use web servers software the most?
The industries with the most detected sites in this category are Construction, IT Services and IT Consulting, Retail, Business Consulting and Services, Advertising Services. Industry mix follows where these tools get installed, so a category carried by website builders or agency templates will lean toward the verticals those platforms serve rather than the vendor's target buyer.
Which countries have the highest adoption of web servers tools?
We detect the most web servers sites in United States, United Kingdom, Germany, Brazil, India. Country here is the company's registered location in our enriched data rather than where the site is served from, so read it as a ranking of markets rather than a measure of any single one.
How do I choose the right web servers platform?
Start from your own size, industry and primary use case rather than from share. Apache HTTP Server, Nginx and LiteSpeed are the three we detect most often in this category, which tells you what is common, not what fits you. Compare their integrations, pricing tiers and support commitments against the workflow you actually run, and check each vendor's own documentation for current capabilities.
How many companies use web servers software?
TechnologyChecker.io detects web servers tools on 13,859,021 live sites. That is a count of sites carrying the technology, not a count of paying customers, and a site running two tools in this category is counted under each. We crawl 2 billion+ URLs across 29.9M live business domains each sweep.
