Companies Using Tailwind CSS

As of our October 2026 crawl, TechnologyChecker.io detects Tailwind CSS on 3,243,962 domains, with 1,527,517 of them matched to a company record. That puts Tailwind #2 of the 85 technologies in UI & CSS Frameworks, with a 24.16% share. I read the number as a ceiling rather than a census, because one part of our detection, a test for utility class names, also fires on some pages that don't use Tailwind; the note at the bottom of this page shows how big that effect was in a 60-domain check. A month before this crawl, on 9 September 2026, Tailwind Labs announced that it is joining Shopify, and that is the question most people searching for Tailwind this autumn want answered.

Growth trajectory: reach, not adoption

Tailwind CSS went from 1,979,907 domains in June 2026 to 3,243,962 in October 2026 on our chart. I wouldn't sell that as 64% growth in four months. The set of domains we crawl turns over every month, with dead sites dropping out and newly found ones added, and our detection signals widen over time, so the line mixes Tailwind adoption with changes on our side. Our records of Tailwind start in November 2018; the chart shows only the current crawl window.

The npm registry shows the same direction: it counted 31,918,803 tailwindcss downloads in the week of 3 to 9 January 2026 and 135,532,035 in the week of 3 to 9 October 2026, per the npm registry. Downloads include CI runs and other automated builds, so they overstate real projects, but a more than fourfold rise in nine months isn't what a fading framework looks like. On the exit side, we've seen 448,434 domains drop Tailwind since we began tracking it on 16 March 2026, a count of observed exits rather than a lifetime total.

"Tailwind's domain count and its npm downloads both climbed this year, but only one of them is about websites. I'd quote 3.24 million as reach and keep the download curve for the momentum question." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales Signal: the Tailwind base is large and still being installed into, so it suits volume prospecting for developer tools and hosting. Don't time outreach off the chart's month-to-month steps; they include our own coverage changes.

Customer profile: small builders, and big companies on one site

Small companies dominate. In our October 2026 data, 63.77% of Tailwind CSS companies with a known headcount have 1 to 10 employees and 22.98% have 11 to 50, so 86.75% have 50 staff or fewer. Founding years lean young as well: 37.69% were founded in the 2010s and 32.31% in the 2020s, 70% since 2010 in all, against 3.39% before 1960.

The enterprise tail is thin by share, 0.28% above 10,000 employees, but that is 3,989 companies. We opened the detected page for every large company we name. Some run Tailwind on the main corporate site: PepsiCo, LVMH, AXA, BP, SLB, SGS, Schneider Electric and Pertamina. More often Tailwind sits on one property: careers sites at T-Mobile, Sainsbury's and WSP's German arm, store locators at Wells Fargo, Family Dollar and Pizza Hut, newsrooms at Samsung and Northrop Grumman, and product sites such as IBM's bob.ibm.com.

Sales Signal: in a 1 to 10 person company, whoever chose Tailwind sits close to whoever buys tools. At the large ones, find the team behind the specific property, the careers site or the store locator, not the corporate web team.

Industry and geography

No industry holds more than 6% of Tailwind CSS companies in our October 2026 data. The technical cluster leads: IT Services and IT Consulting (5.78%), Software Development (5.77%) and Technology, Information and Internet (4.4%) add up to 15.95%. Retail (4.12%), Business Consulting (3.13%), Advertising Services (2.79%), Real Estate (2.74%), Financial Services (2.55%) and Construction (2.52%) follow, which reads more like a web agency's client list than a developer niche.

By country, the United States has 415,768 matched Tailwind companies, about 3.8 times the United Kingdom's 109,491. India is third with 96,118, ahead of Germany (81,684) and Brazil (71,119). Add Canada (49,352) and Australia (46,359) to the US and UK and the four large English-speaking markets hold 620,970 companies; France (52,060), the Netherlands (47,445), Spain (29,794) and Italy (27,108) carry continental Europe beyond Germany.

Sales Signal: India and Brazil both sit in Tailwind's top five, so a Tailwind-targeted list needs more than an English-language sequence. The 78,355 IT-services firms are largely agencies: sell them tools they can resell or reuse across client sites.

Tailwind CSS vs Bootstrap: share, overlap and installs

Bootstrap still runs on more sites: 5,997,454 domains (44.67%) against Tailwind CSS's 3,243,962 (24.16%) in our October 2026 crawl, about 1.85 to 1. We don't publish a Tailwind-Bootstrap switching figure. CSS frameworks stack on one site, and a site that drops one during a redesign rarely shows a clean handover, so a switch count would mostly measure redesign noise. What we can measure is overlap: in a 1% sample of our crawl, 4,438 of 33,833 Tailwind domains (13.12%) also run Bootstrap.

Part of that overlap is real and part is our class-name test. In our 47-site check, 9 Tailwind-detected sites showed no Tailwind CSS at all, and 6 of those 9 loaded Bootstrap. On installs the order flips: npm counted 135,532,035 tailwindcss downloads in the week to 9 October 2026 against 5,893,475 for bootstrap, about 23 to 1.

"Bootstrap has the installed base and Tailwind has the new projects. On websites the gap is under two to one; on weekly npm installs it's twenty-three to one the other way." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales Signal: a domain carrying both frameworks can be worth a redesign or design-system pitch, but open the page first. In our sample, a Bootstrap site matching only Tailwind-like class names was the most common false positive.

Technology ecosystem

Across the 3,187,624 cleaned live Tailwind CSS domains in October 2026 (percentages estimated from a 10% sample), Next.js is the most common framework at 19.69%, then React Router (10.42%), Vue.js (10.04%), Astro (6.96%), React (6.41%) and Alpine.js (5.94%). From Alpine's side the pairing is far tighter: per the Alpine.js profile, Tailwind runs on 79.87% of the 226,035 cleaned domains in our list of companies that use Alpine.js. Alpine nearly always arrives with Tailwind, while only about one Tailwind site in seventeen arrives with Alpine.

Older stacks run Tailwind too. In October 2026, jQuery appears on 29.49% of Tailwind domains and jQuery Migrate on 11.07%, WordPress on 13.08% and Elementor on 3.69%, while Lucide icons (22.7%) and Framer Motion (9.63%) mark the newer React builds. Cloudflare serves 49.59% of Tailwind domains. On analytics, Google Analytics leads at 41.72%, with Cloudflare Browser Insights at 11.61%, Vercel Analytics at 2.83% and Plausible at 2.09%.

Sales Signal: Tailwind plus Next.js or Astro marks a team that chose its own front end recently; Tailwind plus jQuery and WordPress usually marks an agency-built marketing site. Pitch developer tooling and hosting to the first, and site management or conversion tools to the second.

What the Shopify announcement changes

On 9 September 2026 Adam Wathan wrote on Tailwind's blog that "Tailwind is joining Shopify", to give the framework "a stable long-term home". The post gives no deal terms. It says Tailwind CSS and Tailwind Labs' other open-source projects stay MIT-licensed and that the team keeps maintaining them with Shopify's support, and it puts installs at "over 110 million times per week". On the commercial side, Tailwind Labs will no longer try to grow the business: existing customers keep Tailwind Plus and ui.sh, and sign-ups for new customers are closing.

For anyone selling into the 3,243,962 Tailwind domains, nothing on those sites changes: Tailwind is compiled into each site's own CSS and keeps working whatever happens to the company behind it. The paid layer is what changes. Teams that would have bought Tailwind Plus components as new customers can't, which leaves room for other Tailwind component kits.

Sales Signal: component libraries, templates and design-system tools built for Tailwind have an opening with new buyers now that Tailwind Plus is closed to them. Quote the announcement accurately: Tailwind Labs said "joining", not "acquired".

Key takeaways

1. Second by sites, first by installs. Bootstrap has 5,997,454 domains to Tailwind's 3,243,962; weekly npm downloads run about 23 to 1 the other way.

2. Read the headline as a ceiling. 35 of 47 sampled live sites showed Tailwind's own CSS; 9 showed none.

3. A small-company base. 63.77% of matched companies have 1 to 10 employees and 70% were founded since 2010.

4. Enterprise use is per property. 3,989 companies have more than 10,000 staff, usually running Tailwind on a careers site, locator or newsroom.

5. The framework stays MIT-licensed; the paid layer is closed to new buyers. Tailwind Labs announced on 9 September 2026 that it is joining Shopify and is closing new sign-ups.

Sales applications

Outreach template: "We noticed [Company]'s [careers site] is built with Tailwind CSS and Next.js. With Tailwind Plus closed to new customers since September, are you maintaining your own components or looking at a kit?"

Targeting strategy: filter TechnologyChecker.io for Tailwind CSS plus Next.js or Astro, 11 to 200 employees, in IT Services or Software Development. Hold back any domain that also shows Bootstrap until you've opened the page.

Competitive angle: the Tailwind domains that also run Bootstrap, 13.12% in our sample, include sites carrying two CSS systems at once. Once checked, those are a natural audience for consolidation or design-system work.
