Thymeleaf is a modern server-side Java template engine for both web and standalone environments, capable of processing HTML, XML, JavaScript, CSS, and plain text. Its primary goal is to bring elegant natural templates to development workflows — HTML pages that can be correctly displayed in browsers as static prototypes while also working as dynamic server-side templates. With over 3,000 GitHub stars, Thymeleaf 3.1 offers deep Spring Framework integration via the Spring Standard Dialect using Spring EL, extensive tool support for Eclipse and IntelliJ IDEA, and an extensible dialect system. It is widely used in Spring Boot web applications as the standard server-side rendering solution.
