Companies Using Mustache

We detect Mustache on 281,165 domains, including Amazon Literary Partnership, Cognizant Technology Solutions Corporation, 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 Retail (6.93%).

We detect 281,165 domains running Mustache across our monthly crawl of live business domains. Company data could be matched for 155,177 of them (55.2%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 19,202 domains carried a Mustache detection previously and no longer do.

Mustache holds 4.08% of the JavaScript Frameworks category, ranking #6. 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.

Within the JavaScript frameworks category the larger alternatives are React (42.4% share), Vue (12.59%), AMP (9%), React Router (5.7%) and Zone.js (4.73%). Handlebars is the closest template-specific comparison, offering similar logic-less syntax with helper extensions. We publish no switching figures between them: these libraries overwhelmingly coexist rather than replace one another, so a "switchers" count here would be measuring pages that added a library, not pages that changed one.

United States leads with 61,428 matched Mustache domains, followed by Germany (31,527), United Kingdom (9,663), France (6,758), Canada (6,310). These are counts within the 155,177 domains we could match to a company record, not the full detected base.

The most common company size is 1-10 employees, representing 77.57% of the Mustache domains we could match to a company record and size — a subset of 155,177 matched companies, not of all 281,165 detected domains. This is followed by 11-50 employees (16%) and 51-200 employees (3.68%).

Among the Mustache domains we could match to a company with a known founding date, most were founded in the 2010s (43.72%), followed by the 2000s (18.77%). That matched subset is drawn from 155,177 companies and is not representative of all 281,165 detected domains. This suggests Mustache is most popular among relatively young companies.

The ideal Mustache customer is: Company Age: Founded 2010-2019, Industry: Technology, Enterprise, Company Type: Public Company, Government, Use Case: Server-side templating, Developer Focus: Multi-language support — based on our analysis of 155,177 enriched companies at TechnologyChecker.io.

Mustache is a logic-less web template system that works with HTML, config files, and source code. It expands tags in templates using values from a hash or object, without explicit control flow statements like if/else conditionals or for loops. Mustache is available in multiple programming languages including JavaScript, Ruby, Python, PHP, and Java.

Yes. Our data shows Mustache active on 281,165 domains with 155,177 enriched company profiles at TechnologyChecker.io, ranking #6 in the JavaScript frameworks category at 4.08% share. We publish no decline figure: our current crawl window covers June to August 2026 only, and Mustache rose across it. What we can say is that 19,202 domains have dropped Mustache since we began tracking it in March 2026 — modest churn for a library this size.

Enterprises running Mustache on production domains include Siemens, Cognizant, HP, Boeing, Pfizer, Nike, Uber, Johnson & Johnson, Costco and ING Group. They deploy it for server-side rendering, internal tools and multi-language applications where logic is kept out of the presentation layer. Worth knowing before you read too much into the total: roughly two-thirds of Mustache's 281,165 active domains also run Weebly or Jimdo, where the template engine ships with the builder rather than being chosen.

Mustache is strictly logic-less with no control flow statements, while Handlebars extends Mustache with helpers and block expressions. We do not publish a switching count between them, because the two coexist far too often for such a count to mean anything — sharing a build is the normal state for template engines, not evidence of a move. The choice comes down to whether you want pure separation (Mustache) or practical helper functions (Handlebars).

We cannot confirm from our own data that it is. Our current crawl window runs June to August 2026 and Mustache rose across it, from 255,156 to 281,165 active domains, though much of that reflects our crawl widening rather than new installations. The wider argument — that component frameworks combining templating with reactivity and state management have displaced standalone template engines — is well supported in the industry generally, but we publish no migration figures to back it here, because the domains that run Mustache alongside those frameworks overwhelmingly still run both.

Mustache implementations exist for JavaScript, Ruby, Python, PHP, Java, C++, Go, Perl, Objective-C, .NET and many others. That multi-language support is the main reason enterprises such as Siemens and Cognizant adopted it: teams can use the same template syntax across polyglot technology stacks, rather than being locked into one language's framework-specific solution.

No, Mustache is intentionally logic-less and lacks explicit if/else statements. Conditional rendering uses section tags that process lists and lambdas, but all logic must exist in the data layer, not the template. This separation is why government agencies and regulated industries favor Mustache, templates become auditable presentation layers with no hidden business logic.

Mustache is a standalone template engine that needs separate JavaScript for interactivity, while Vue integrates templates with reactive data binding and a component lifecycle. They are not really rivals in practice: 86.8% of domains that have ever run both still run both, which is why this profile publishes no switching numbers between them. Mustache's multi-language support and strict logic separation continue to suit polyglot enterprise teams maintaining server-rendered applications.

Based on our enriched company data, Retail leads at 6.93% of Mustache domains, followed by Medical Practices (4.31%), Real Estate (4.26%), Construction (4.09%) and Individual and Family Services (3.68%). That profile reflects the hosted website builders underneath much of Mustache's footprint — Weebly and Jimdo together account for around two-thirds of these domains, and they serve exactly these local and trade sectors. The separate enterprise cohort spans manufacturing (Siemens), IT services (Cognizant, HP), aerospace (Boeing), pharmaceuticals (Pfizer) and retail (Nike, Costco).

Mustache's logic-less design does reduce attack surface by keeping all logic in the data layer, and the strict separation makes templates easier to review for XSS vulnerabilities. On infrastructure, 84.07% of Mustache domains sit behind Cloudflare. We would not cite specific government or healthcare deployments as evidence: those we can currently verify are enterprises such as Boeing, Pfizer and Johnson & Johnson rather than the public-sector bodies previously listed here.

Consider migration if you are building interactive single-page applications or need reactive data binding — Vue, React and Svelte offer integrated templating with state management. Keep Mustache if you need multi-language support across polyglot stacks, strict logic separation for compliance, or server-side rendering in established applications. Our data shows 281,165 domains still running Mustache in 2026, across 155,177 enriched company profiles — though remember that around two-thirds of those are website-builder deployments where nobody made the choice explicitly.
