Companies Using Ruby on Rails

We detect Ruby on Rails on 203,189 domains, including gov.uk, The Walt Disney Company, Nokia. A detection means the technology is present on that domain, which for large organisations is often a single storefront or subdomain rather than a company-wide deployment. Among domains we matched to a company with a resolved industry, the most common is Software Development (5.08%).

We detect 203,189 domains running Ruby on Rails across our monthly crawl of live business domains. Company data could be matched for 99,510 of them (49.0%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 22,767 domains carried a Ruby on Rails detection previously and no longer do.

Ruby on Rails holds 10.96% of the Web Frameworks category, ranking #2. This is a share of the domains we detect running a platform in this category — not a share of all websites, and not a share of spending — so it is not directly comparable to figures published on other denominators.

The top alternatives to Ruby on Rails include Microsoft ASP.NET (46.19% market share), Nuxt.js (10.25% market share), Express (7.46% market share), Laravel (4.87% market share) — measured as a share of the domains we detect running a platform in this category.

United States leads with 45,277 matched Ruby on Rails domains, followed by United Kingdom (7,066), France (5,434), Canada (4,012), Germany (3,161). These are counts within the 99,510 domains we could match to a company record, not the full detected base.

The most common company size is 1-10 employees, representing 64.7% of the Ruby on Rails domains we could match to a company record and size — a subset of 99,510 matched companies, not of all 203,189 detected domains. This is followed by 11-50 employees (21.38%) and 51-200 employees (8.25%).

Among the Ruby on Rails domains we could match to a company with a known founding date, most were founded in the 2010s (43.29%), followed by the 2020s (21.23%). That matched subset is drawn from 99,510 companies and is not representative of all 203,189 detected domains. This suggests Ruby on Rails is most popular among relatively young companies.

The ideal Ruby on Rails customer is: Company Age: Founded 2010-2019, Company Size: Mostly 1-50 employees, Common Industries: Software, Retail, Restaurants, Typical Use: Web apps, portals, APIs, Typical Deployment: One portal or subdomain — based on our analysis of 99,510 enriched companies at TechnologyChecker.io.

Major organisations still running Ruby on Rails in 2026 include gov.uk, Airbnb, The Walt Disney Company, Nokia, Salesforce, Shopify, NVIDIA, ANZ, Instacart and Databricks, alongside a long list of universities and government agencies. Our database tracks 203,189 domains actively running Rails. Because the count is domains rather than companies, one organisation with Rails on several subdomains shows up more than once.

Yes. Rails is the second most widely detected web framework we track, on 203,189 domains and 10.96% of the Web Frameworks category, behind only Microsoft ASP.NET. It is also one of the few frameworks in the category adding domains faster than it loses them: over the last 30 days it gained roughly 13,956 and lost 7,964, a net gain near 6,000, the strongest in the category.

We detect Ruby on Rails on www.airbnb.com. Airbnb has moved substantial parts of its platform to Java-based services over the years, and a detection on one domain does not tell you what runs behind every internal service. What it does confirm is that Rails is still present on the main Airbnb site, which is the pattern across most large Rails users: Rails on some properties, other stacks elsewhere.

The largest outbound corridor is to Nuxt.js, with 315 domains moving that way, though Rails gains more back from Nuxt.js (377) than it loses. Beyond that the outbound flows are small: 87 domains to Microsoft ASP.NET, 71 to Express, 23 to Laravel. Rails gains more than it loses against every one of those, so the net direction of framework switching currently favours Rails.

Speed to a working application is the reason reviewers give most often, and the enterprise deployments we detect fit that: careers portals, event calendars, developer sites, support and payment subdomains, the kind of internal or adjacent application a small team needs to ship without a long build. Note that enterprises are a small part of this base. Organisations of 1,000 or more employees account for 1.64% of the domains we can match to company records.

The data points firmly at small teams. Of the 99,510 Rails domains we can match to company records, 64.7% belong to organisations of 1 to 10 employees and 21.38% to those of 11 to 50. Companies above 1,000 employees make up 1.64%. Rails clearly works at enterprise scale, since gov.uk, Shopify and Airbnb run it, but the typical Rails deployment is a small team's application.

Two different figures get quoted here, so it is worth separating them. Rails holds 10.96% of the Web Frameworks category, which is its share among the 89 framework technologies we detect. Measured against all 29.9M active domains in our monthly crawl, the 203,189 Rails detections work out at roughly 0.7%. The first number is the one used in category rankings; the second is the share of the web as a whole.

Across 99,510 matched Rails domains, jQuery appears on 75.07%, Google Analytics on 64.55% and Cloudflare on 64.33%. core-js (47.26%) and jQuery Migrate (27.7%) are also common, which reflects server-rendered pages with older JavaScript layered on. On the CSS side Tailwind CSS (28.77%) has overtaken Bootstrap (19.63%). Ahoy, the Rails-native analytics gem, appears on 4.33%.

Software Development leads with 4,321 domains (5.08%), followed by Retail (3,967, 4.66%), Technology, Information and Internet (2,967, 3.48%), Restaurants (2,903, 3.41%) and Professional Training and Coaching (2,699, 3.17%). No industry clears 6%, which is what a general-purpose framework looks like. These shares describe the subset of domains we can match to company records, not all 203,189 detections.

Raw request throughput depends far more on architecture than on framework choice, and our detection data cannot measure it. What we can see is which way domains move. Rails gains 225 domains from Microsoft ASP.NET while losing 87, close to 2.6 to 1, and trades near evenly with Express (83 gained, 71 lost). Reviewers name performance under load as the main Rails criticism, usually resolved with caching and query tuning rather than a framework change.

Yes. Our detections include gov.uk, the United Kingdom's single government domain and one of the best known public sector Rails deployments, plus the Metropolitan Police news service, Ameli (the French national health insurance service), Peru's Ministry of Education and social health insurer EsSalud, and Los Alamos National Laboratory. Government Administration is a recurring category in the company list.

22,767 domains have dropped Ruby on Rails since we began tracking in March 2026, set against 203,189 that currently run it. That is a churn figure for a short window, not a lifetime total, and it should be read next to the inflow: over the last 30 days Rails added roughly 13,956 domains against 7,964 lost, so the base is growing rather than draining.

Growing, and it is the strongest net gainer in the category. Over the last 30 days Rails added about 13,956 domains and lost 7,964, a net gain near 6,000. Microsoft ASP.NET, which holds 46.19% of the category, added 5,490 and lost 9,939 for a net loss around 4,449. Express also grew, by roughly 5,227 net, while Laravel shrank. The category leader is losing domains and Rails is picking up more of them than anyone else.

Partly because it is bigger, and partly because it is easier to see. ASP.NET is detected from URL extensions such as .asp and .aspx as well as from headers and cookies, which is a far wider surface than a framework identified only by a runtime signature. Express, at the other extreme, is found by a single header. Every count in this category is a floor measured with a different instrument, so the ordering is approximate and the gaps between frameworks should not be read as precise.

We do not currently detect Ruby on Rails on Netflix domains. Netflix runs its core streaming platform on Java-based services, and a framework that leaves the public-facing estate can still remain on internal tooling we would not see. This is the general limit of detection data: it covers what a public domain reveals, so absence is weaker evidence than presence.

Because that is where large organisations put it. The detection URLs in our company list are dominated by careers.nab.com.au, developer.nvidia.com, events.stanford.edu, support.springernature.com and similar properties. Enterprises frequently keep their main marketing site on a CMS and use Rails for a portal, calendar, directory or payment application beside it. It also means a Rails detection on a large brand is evidence about one team, not an estate-wide standard.
