It ships about 50 components, including dialogs, date pickers, tables, charts and a full application shell, inspired by shadcn/ui. Themes are controlled through shadcn's CSS variables like '--primary' and '--radius', with nine built-in skins. Components validate their own props, so mistakes like a bad variant value fail with a clear error instead of reaching the browser. It requires Java 17 and Spring Boot 4.1, and includes a dedicated guide plus an 'llms.txt' index for reading documentation with coding agents like Claude Code or Cursor. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Is there a shadcn-style UI component library for Thymeleaf and Spring Boot? Yes, it is called Shadleaf, an open-source library of about 50 accessible, themeable components for Thymeleaf, packaged as a Spring Boot starter and inspired by shadcn/ui. It includes buttons, dialogs, date pickers, tables, charts and full page layouts, themed through shadcn-style CSS variables like '--primary' and '--radius', and requires Java 17 with Spring Boot 4.1. _Developers picking a Thymeleaf component library can track releases like Shadleaf 1.0 on daily.dev._ ### How do I stop AI coding agents from hallucinating React-style APIs when generating Thymeleaf templates with Shadleaf components? Paste a short block of project rules into your AGENTS.md or CLAUDE.md file describing things agents commonly get wrong, such as how a dialog opens or how to bind a form field. Shadleaf also publishes every documentation page as Markdown plus an llms.txt index, and its checked props fail with a clear error at render time when an agent uses a wrong prop or invalid value. _Developers wiring new libraries into Claude Code or Cursor track setup tricks like this on daily.dev._ ### What Java and Spring Boot versions does the Shadleaf Thymeleaf component library require? Shadleaf needs Java 17 and Spring Boot 4.1. It is added as a Maven dependency via the 'shadleaf-spring-boot-starter' artifact, version 1.0.2, from the io.github.wimdeblauwe group. _Developers upgrading Spring Boot stacks check version requirements like this on daily.dev before adopting a library._ ## Similar posts on daily.dev - [Shadcn UI adoption guide: Overview, examples, and alternatives](https://daily.dev/posts/shadcn-ui-adoption-guide-overview-examples-and-alternatives-0pr6z5eli) · LogRocket · 1 upvotes · 0 comments --- Tags: [#java](https://daily.dev/tags/java), [#spring-boot](https://daily.dev/tags/spring-boot), [#shadcn](https://daily.dev/tags/shadcn), [#htmx](https://daily.dev/tags/htmx) [View this post on daily.dev](https://daily.dev/posts/shadleaf-1-0-release-nk1ett3hi) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Shadleaf 1.0 release","url":"https://daily.dev/posts/shadleaf-1-0-release-nk1ett3hi","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/shadleaf-1-0-release-nk1ett3hi"},"datePublished":"2026-10-29T17:32:19.357Z","dateModified":"2026-10-29T17:41:47.580Z","description":"Shadleaf 1.0 is an open-source UI component library for Thymeleaf, packaged as a Spring Boot starter.
