Mustache.java is a Java implementation of the mustache.js logic-less templating system with no external dependencies. It supports template inheritance, lambdas, concurrent evaluation via ExecutorService, and passes the official mustache specification tests.

Use cases

• render mustache templates in a Java web application
• logic-less HTML templating for server-side rendering
• share the same mustache templates between JavaScript frontend and Java backend
• render emails from templates in Java
• concurrently evaluate template sections for performance
• prototype templates with mock JSON data using the handlebar server

When to choose

• you need a fast, dependency-free mustache engine on the JVM
• you want logic-less templates shared with mustache.js clients
• you need template inheritance or concurrent evaluation beyond the mustache spec
• you want a battle-tested library used at large scale (e.g. Twitter)

When to avoid

• you need to render templates supplied by untrusted users without using SafeMustacheFactory whitelisting
• you need a full logic-capable template engine like FreeMarker or Thymeleaf
• you are not on the JVM or Java 8+
