Companies Using Handlebars

We detect Handlebars on 211,982 domains, including Walmart Community Grants Team, PwC, Siemens AG. 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 Real Estate (8.8%).

We detect 211,982 domains running Handlebars across our monthly crawl of live business domains. Company data could be matched for 95,249 of them (44.9%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 26,418 domains carried a Handlebars detection previously and no longer do.

Handlebars holds 0.25% of the JavaScript Libraries category, ranking #40. 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 Handlebars include jQuery (18.51% market share), core-js (12.13% market share), jQuery Migrate (9.86% market share), jQuery UI (5.64% market share) — measured as a share of the domains we detect running a platform in this category.

United States leads with 39,273 matched Handlebars domains, followed by United Kingdom (6,976), Germany (4,719), Canada (4,630), Australia (3,808). These are counts within the 95,249 domains we could match to a company record, not the full detected base.

The most common company size is 1-10 employees, representing 64.99% of the Handlebars domains we could match to a company record and size — a subset of 95,249 matched companies, not of all 211,982 detected domains. This is followed by 11-50 employees (20.74%) and 51-200 employees (7.6%).

Among the Handlebars domains we could match to a company with a known founding date, most were founded in the 2010s (39.01%), followed by the 2000s (16.95%). That matched subset is drawn from 95,249 companies and is not representative of all 211,982 detected domains. This suggests Handlebars is most popular among relatively young companies.

The ideal Handlebars customer is: Company Size: Enterprise (10,001+ employees), Location: US, UK, or Germany, City: New York, London, Seattle, Bonn, Founded: 2010-2019, Company Age: ~10-15 years old — based on our analysis of 95,249 enriched companies at TechnologyChecker.io.

Yes. Our data shows 211,982 active domains running Handlebars, and we do not publish a decline figure — our current crawl window covers June to August 2026 and Handlebars rose across it, though largely because our crawl widened. Churn is low: 26,418 domains dropped it since March 2026, about one in nine. It remains widely used for server-side rendering, email templates and PDF generation.

Enterprises we currently detect running Handlebars include PwC, Bank of America, Microsoft, SAP, HSBC, Allianz, Siemens, Kaiser Permanente, AstraZeneca and Lowe's. Most deploy it for server-side templating in content-heavy or regulated environments. They are not typical of the base by count — 64.99% of Handlebars domains belong to companies with 1-10 employees.

Handlebars is a JavaScript templating library that creates reusable templates by combining HTML, text, and expressions. It's primarily used for server-side rendering in Node.js applications, email template generation, PDF creation, and static site generation. Its logic-less philosophy keeps presentation separate from business logic, making it popular in enterprise environments that require strict template governance.

No, handlebars is a templating engine, not a full framework. Unlike React or Vue, which provide component architecture and state management, Handlebars focuses solely on rendering templates from data. It's often used with Express.js via the hbs module for server-side rendering. It provides no built-in routing, data fetching, or application structure.

Handlebars works best for server-side rendering where you don't need client-side interactivity. It is lighter than React or Vue, has no virtual DOM overhead, and integrates directly with Node.js email services and PDF generators. The two are not really alternatives in practice — our data shows only 3.82% of Handlebars domains also run React, and Backbone.js actually appears more often at 7.8%. Handlebars estates are predominantly traditional server-rendered stacks, with jQuery on 97.15% of them, rather than hybrid React architectures.

Handlebars expressions are content enclosed by double curly braces, like {{firstname}}, that get replaced with data values at render time. Expressions can reference data fields, use built-in helpers like {{#each}} for iteration, or call custom helpers you define. This lets you extend templating functionality without adding business logic to the template itself.

Yes, handlebars is largely compatible with Mustache templates. In most cases, you can swap Mustache with Handlebars and keep using existing templates. Handlebars extends Mustache with helpers, partials, and block expressions while maintaining the logic-less philosophy. This compatibility helped Handlebars gain adoption during the Ruby-to-Node.js migration wave from 2012-2016.

We publish no such figure, and the reason is worth explaining. A switching query cannot distinguish "replaced Handlebars with X" from "added X alongside Handlebars", and in this category it is nearly always the second: every pair we measured sits above 71% still-both, reaching 88.3% for Modernizr and 87.4% for core-js. What we can report is total churn — 26,418 domains have dropped Handlebars since March 2026, roughly one in nine — with no named destination, because we cannot observe where they went.

Handlebars domains most commonly run jQuery (97.15%), core-js (83.2%), Underscore.js (46.26%), Lodash (45.8%) and Modernizr (42.89%). The near-total jQuery overlap signals traditional server-rendered architectures rather than modern single-page apps — as does Backbone.js (7.8%) outranking React (3.82%). Cloudflare fronts 67.3% of these domains.

Yes, Handlebars is actively maintained on GitHub as handlebars-lang/handlebars.js. Development focuses on security patches and compatibility rather than new features, the library reached maturity years ago. Our detection data shows stable enterprise usage despite declining overall adoption, which indicates Handlebars remains reliable for organizations prioritizing stability.

Based on our enriched company data, Real Estate leads at 8.8% of Handlebars domains, almost tied with Retail at 8.51%, then Retail Apparel and Fashion (3.07%), Insurance (1.94%) and Food and Beverage Services (1.77%). Listing and catalogue businesses dominate because they render the same page structure thousands of times, which is what a logic-less template engine is for. The enterprise tier skews to regulated sectors — financial services (Bank of America, HSBC, Allianz, Santander, State Farm) and healthcare (Kaiser Permanente, Roche, Medtronic, AstraZeneca, Novo Nordisk).

For most new projects, modern frameworks like Next.js or Nuxt offer better developer experience and performance. However, Handlebars remains a solid choice for server-side email templating, PDF generation, or projects that need Mustache compatibility. If you don't need client-side interactivity and want minimal dependencies, Handlebars delivers. For dynamic web apps, React or Vue provide superior tooling.

Handlebars uses a logic-less approach where templates contain minimal logic. EJS allows full JavaScript in templates, offering more flexibility but risking mixed concerns. Pug uses indentation-based syntax that's concise but has a steeper learning curve. Handlebars offers the best separation of concerns among the three, though it requires custom helpers for complex logic.
