Cloudflare
Cloudflare is a global network that sits in front of a website, serving it through Cloudflare's own edge instead of directly from the origin server.

Biggest Movers
Expert Insight: CDN Providers Market Share & Momentum
Cloudflare is about 47% of the category, and roughly a third of the rest is not a CDN purchase at all.
Cloudflare runs on about 9.2M of the 19.5M domains where we detect a delivery network, close to half. The next four entries are the problem with reading this as a market: cdnjs, jsDelivr, Google Hosted Libraries and jQuery CDN are public JavaScript library hosts, and together with unpkg they account for roughly 38% of the table. A script tag pointing at a free library host is not the decision a CDN vendor competes for.
Half the table is a script tag, not a supplier
Cloudflare holds about 47%, and it is detected at the nameserver, which is as close to a purchasing decision as this data gets. Then cdnjs at roughly 11%, jsDelivr 11%, Google Hosted Libraries 8%, jQuery CDN 4% and unpkg 3%. Those five are free public hosts a developer references in a template. Google Cloud CDN at about 7% is a third case again: we match it on a proxy header, which appears on anything Google fronts.
The biggest gainer is a hosting default and the biggest loser is a header
Hostinger CDN added about 103,000 domains over 90 days on a base of 487,000, roughly a fifth, which is what a host enabling something by default looks like rather than customers arriving. Cloudflare added about 205,000 over the same window, large in absolute terms and about 2% of its base. Against that, Google Cloud CDN is down roughly 206,000 in 30 days, about 16% of its base, on a signal that is one response header. Four small entries show gains equal to their entire footprint, which means they entered our detection set in the window.
Turnover runs about 3%, and it is concentrated in the library hosts
cdnjs shed roughly 84,000 domains over 30 days, jsDelivr 85,000 and Google Hosted Libraries 58,000. None of those is a cancelled contract. Swapping one library URL for another, or bundling the library locally, removes the detection in a single deploy, which is why the free hosts churn hardest. Dropped here means the reference stopped appearing in our crawl, nothing more.
The paid market is much smaller than the ranking suggests
Strip out the library hosts and the platform defaults and the commercial field is Cloudflare, then Amazon CloudFront at about 398,000 domains, Bunny at 144,000, StackPath 107,000, Fastly 95,000 and Akamai 49,000. Those five below Cloudflare total under 5% of the category. If you are sizing a market to sell into, that is the number, and it is an order of magnitude smaller than the table's headline totals imply.

FAQ.
What is CDN software?
CDN covers the tools a site can load or configure to handle this part of its stack. We detect one of the 59 cdn tools in this category on 19,512,613 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 cdn platforms?
Across 19,512,613 detected sites, the most widely found cdn tools are: Cloudflare (47.33% share, 9,236,181 sites), cdnjs (11.12% share, 2,169,707 sites), jsDelivr (11.05% share, 2,155,845 sites). Others we see regularly include Google Hosted Libraries and Google Cloud CDN.
Which cdn tool has the largest market share?
Cloudflare is the most widely detected cdn tool at 47.33% share, on 9,236,181 sites. The largest share of those sites belongs to Retail companies, and to businesses in the 1-10 employee band.
Which industries use cdn software the most?
The industries with the most detected sites in this category are Retail, IT Services and IT Consulting, Software Development, Construction, Technology, Information and Internet. 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 cdn tools?
We detect the most cdn sites in United States, United Kingdom, Canada, Australia, Brazil. 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 cdn platform?
Start from your own size, industry and primary use case rather than from share. Cloudflare, cdnjs and jsDelivr 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 cdn software?
TechnologyChecker.io detects cdn tools on 19,512,613 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.
What is the source of this data?
