Companies Using Turbopack

I'm David Thomson, CTO at TechnologyChecker.io, and I maintain the detection rules behind this page. Our Turbopack rule is short. It looks for the global that Turbopack's production bundles register in the browser, so it sees what a site shipped to production, not how its developers run their dev server. Our October 2026 crawl finds that global on 345,255 live domains, 191,577 of them matched to a company record. When we checked on 8 October, 344,118 of 344,784 Turbopack domains also ran Next.js. So read every number below as Next.js sites that build with Turbopack.

Measured against Next.js

The raw line climbs fast: 135,563 domains in June, 205,575 in July, 241,375 in August, 313,749 in September and 345,255 in October. Some of that is our side. The domains we crawl turn over every month, with dead sites dropping out and new ones added, and our detection widens over time. Next.js's own count grew on the same crawl, from 544,460 to 903,683, and that gives a fair yardstick. Turbopack's share of Next.js domains went from 24.9% in June to 38.21% in October, and it rose in every month in between. Changes in coverage lift both lines. They don't explain one line gaining on the other.

The timing fits the release history. Next.js 15.5 put Turbopack production builds into beta in August 2025, and Next.js 16, released on 21 October 2025, made Turbopack the default bundler for development and production. A team gets it by upgrading and changing nothing else.

"Turbopack arrives with a Next.js upgrade, and upgrades happen across thousands of sites a month. That's why its share of Next.js sites went from about a quarter to 38% in four months." - David Thomson, CTO at TechnologyChecker.io

Sales signal: a Turbopack detection tells you a Next.js site was built on a recent release, most likely version 16. The other 61.79% of Next.js domains don't show a Turbopack build. Most are on an older release or have kept Webpack, and that is the list for upgrade and migration work.

Who the customers are

61.63% of matched companies with a known size have 1 to 10 employees and 24.21% have 11 to 50. 40.6% were founded in the 2020s, which is what you'd expect when new companies start on the newest framework release. The top of the list is broad, though: 3,048 companies have more than 1,000 staff. At those, the Turbopack build usually belongs to one site and one team. SAP and Uber run it on their careers sites, IBM on developer.ibm.com, NVIDIA on build.nvidia.com, PwC on its alumni network and Mercedes-Benz on its museum ticket shop. Visa's US site, Takeda, TUI Group and Burlington run it on their main domains, and so does the U.S. Department of Veterans Affairs on www.va.gov.

Sales signal: at a large account, find the team that owns the Next.js property. A careers site or a developer portal has a different owner, budget and agency from the corporate homepage.

Where they are and what they do

The United States leads with 46,734 matched companies, then India (16,552), the United Kingdom (10,767), Brazil (9,552) and Germany (7,859). It's the same order as our Next.js profile, India in second place included. By industry, Software Development (9.36%), IT Services and IT Consulting (8.11%) and Technology, Information and Internet (6.71%) add up to 24.18%. The rest is spread thin: Financial Services 3.28%, Business Consulting 3.09%, Advertising Services 3.09% and Real Estate 2.71%. Advertising Services is LinkedIn's label for agencies, and it's as large here as Business Consulting.

Sales signal: India and Brazil hold 26,104 matched companies between them, more than the United Kingdom and Germany combined (18,626). A Next.js services pitch aimed at Indian or Brazilian companies reaches a bigger slice of this list than one aimed at Germany.

The Webpack "migration" is a build flag

Our switching table says 5,797 domains dropped Webpack and kept Turbopack since March 2026, 1,818 of them in the last 30 days and 4,649 in the last 90. Webpack and Turbopack are both bundlers inside the same Next.js project, so this is a build setting changing, and Next.js 16 changes it by default. 999 of those domains still serve a Webpack build on another hostname, so the move often happens one site at a time. The reverse flow is small: 341 domains dropped Turbopack and run Webpack, which is what the --webpack flag does, or a redeploy we caught on the older build. The Babel rows (1,140 in, 79 out) are a side effect, because Turbopack builds don't ship Babel's helper code.

The one row that implies a rebuild is Vite. 431 domains dropped a Vite build and now run Turbopack, and 61 went the other way. That's a change of framework rather than a setting, and it runs about seven to one toward Next.js. It's also small next to Vite's 95,246 domains.

"Webpack to Turbopack is the biggest flow in this table and the least interesting one commercially. Nobody chose a new vendor. A Next.js team ran an upgrade." - David Thomson, CTO at TechnologyChecker.io

Sales signal: a domain that moved in the last 30 days has just been through an upgrade, which is a good moment for a performance audit or a hosting review. Turbopack doesn't run webpack plugins, so a vendor whose Next.js integration is a webpack plugin should check how its customers build now.

The stack: Tailwind nearly everywhere, Vercel on half

The percentages here are of the 348,542 live Turbopack domains in our clean set. Tailwind CSS is on 84.73%, Radix UI on 29.44% and shadcn/ui on 18.46%. Hosting is split. Vercel serves 49.91%, Amazon Web Services 10.9%, Netlify 2.69%, Firebase 2.43% and Supabase 2.09%. Google Analytics runs on 41.39%, Vercel Analytics on 14.38% and Cloudflare Browser Insights on 12.22%. Few of these sites show a CMS: Sanity, the largest, is on 3.8%, just ahead of WordPress at 3.57%.

Sales signal: half this list hosts somewhere other than Vercel, a ready audience for other hosts and for CDN vendors. For component and design-system vendors, the Radix UI and shadcn/ui shares show who has already standardised and who hasn't.

What it costs

Nothing directly. Turbopack lives in the Next.js repository, which is released under the MIT licence, and Vercel, which makes both, sells hosting rather than the bundler. The money around a Turbopack site goes to hosting, analytics and whoever builds it.

Sales signal: with no licence fee there's no renewal date to work around. The buying moments are a framework upgrade and a hosting review.

Key takeaways

1. 345,255 live domains, 99.81% of them Next.js sites.

2. Turbopack's share of Next.js domains rose from 24.9% to 38.21% between June and October 2026.

3. The 5,797-domain Webpack flow is a build setting, not a change of vendor.

4. A small, young base (61.63% with 1 to 10 staff, 40.6% founded in the 2020s) with 3,048 companies above 1,000 staff.

5. Tailwind CSS on 84.73% of domains, and Vercel hosting 49.91%.

How to use this list

Filter by company size and country, then look at the hostname: a careers or developer subdomain has a different owner from the main site. For the full list of 345,255 Turbopack domains with company, size and stack data, and to compare it with Next.js as a whole, explore TechnologyChecker.io.
