Companies Using Inertia.js

I'm David Thomson, CTO at TechnologyChecker.io, and I look after the detection rules behind this page. Inertia.js is one of the cleaner things we detect: an Inertia page carries a data-page object with the component name and its data, and Inertia's requests carry an X-Inertia header. Our October 2026 crawl finds those traces on 26,896 domains, 14,183 of them matched to a company. We left 1,243 pages out of the company charts, 835 domain-for-sale pages and 408 Indonesian gambling pages, but kept them in the headline, where they're under 5%.

Growth you should discount

The chart goes from 14,013 domains in June to 26,896 in October. Don't read that as adoption doubling in four months. The set of domains we crawl turns over every month, with dead sites leaving and new ones arriving, and our detection widens over time; both push the line up independent of any team choosing Inertia. The October step was only 712 domains, from 26,184. 3,075 domains have dropped Inertia since we began tracking in March 2026.

"Inertia barely shows up as a front-end framework, because it isn't one. You find it on the login screens, portals and careers pages that Laravel teams build every week." - David Thomson, CTO at TechnologyChecker.io

Sales Signal: size the market at about 27,000 domains and treat the June to October rise as partly ours. Laravel's current starter kits ship Inertia 3 for React, Vue and Svelte, so every new project built from them adds to the pool.

Applications, not brochure sites

Read the component names in our company list and you see what Inertia is used for: login and authentication screens, an export portal at Correios, an events site at FNB and eClinicalWorks, an admissions portal at Addis Ababa University, a kitchen planner at Castorama Polska. 36 of the 50 rows run on a subdomain. Many Inertia apps sit behind a login, and our crawl only sees the public page in front of them, so the 26,896 is what's visible from outside. The companies are small and young: 60.31% of matched companies with a known size have 1 to 10 employees, and 70.04% were founded in 2010 or later.

One pattern surprised me. Five careers sites in the list, Yum! Brands, Elastic, Wipfli, SHC and Cambium Learning, serve the identical Inertia build, and Elastic's careers host points at Ongig, a recruiting-software vendor. Those companies didn't choose Inertia; their careers-site vendor did. The same goes for two French charities whose donor portals run the same Inertia app.

Sales Signal: at a large company the Inertia buyer is the team behind one application, or a vendor hosting it for them. For the 83.71% with 50 staff or fewer, the buyer is the developer.

Brazil, third

The United States has 2,238 matched companies, the United Kingdom 1,246 and Brazil 817, ahead of Germany (645) and the Netherlands (620). That's about 1.8 American companies per British one, a flatter spread than Alpine.js's 3.6. Indonesia (389), Mexico (206) and Turkey (205) make the top 15, and our list has a long run of Latin American universities and Brazilian portals. By industry, the three software rows hold 18.17% (7.18%, 5.72% and 5.27%), with Real Estate at 3.48% and Advertising Services, the agencies, at 3.00%.

Sales Signal: Laravel agencies in Brazil and the UK are the densest pool here after the US. Portuguese-language outreach is worth testing before German.

Livewire to Inertia, and Next.js both ways

Since March 2026, 164 domains dropped Livewire and kept Inertia, and 38 did the reverse. The direction holds up against the base rate: about a quarter of the domains we've seen with both dropped Livewire, against about 8% of all Livewire domains. 93 of the 164 fell in the last 30 days, when Livewire's drops were high everywhere, so I'd call it a lean, not a stampede. Next.js runs both ways, 177 in and 238 out, and Next.js still sits on 3.34% of Inertia domains, so many sites run both. Nuxt.js moved 100 in and 74 out.

"When a site that ran both Livewire and Inertia dropped one of them, it kept Inertia four times out of five. Small numbers, but they point one way." - David Thomson, CTO at TechnologyChecker.io

Sales Signal: teams moving from Livewire to Inertia are hiring or contracting React and Vue skills. That's a better hook for front-end agencies than any Inertia-versus-Next.js pitch.

The stack: Tailwind and the starter kits

Tailwind CSS runs on 81.16% of Inertia domains. shadcn/ui is on 20.65% and Radix UI on 18.55%, which is what Laravel's React starter kit installs, per laravel.com. Bootstrap is on 16.25%. Laravel's own cookie and global show on only 5.91%, because a Laravel app can hide them; Ruby on Rails shows on 3.37%. Hosting splits between Amazon Web Services (8.00%) and shared hosts such as Hostinger (6.61%), and Cloudflare Browser Insights is on 19.15%. Fathom (1.85%) and Plausible (1.46%) are the privacy-first analytics picks.

Sales Signal: a shadcn/ui row is close to a starter-kit fingerprint, so those domains are recent Laravel and React builds. Component, auth and hosting vendors aimed at Laravel should start there.

What it costs

Nothing. Inertia.js is MIT-licensed. Jonathan Reinink introduced it in March 2019, using Laravel and Vue as his examples, Laravel's blog announced Inertia 2.0 in December 2024, and Laravel's current starter kits ship Inertia 3. Laravel and Rails have official server adapters and Django a community one.

Sales Signal: there's no vendor relationship to displace. Sell what Inertia apps need around them: hosting, monitoring, auth, components and developer time.

Key takeaways

1. 26,896 live domains, 20th of 69 in a category that compares it with its own dependencies.

2. It runs applications: logins, portals, events and careers sites, mostly at small, young companies.

3. Brazil is the third-largest market, and the US lead over the UK is narrow.

4. Where sites ran both, Livewire lost more often than Inertia: 164 against 38.

5. shadcn/ui on 20.65% marks the Laravel React starter kit.
