Shadleaf

Checked 2026-10-30 against official sources. Official README verifies Shadleaf 1.0.2 for Spring Boot 4.1.x and Java 17+, Maven dependency and sl-prefixed Thymeleaf tags. The jar provides compiled CSS/JavaScript under /shadleaf/**; no Node build is required in a basic consuming app. Optional Tailwind integration and shadcn-style CSS variables allow theme customization; this is not the React shadcn/ui package. Props validation, templates override, strict CSP/Spring Security samples and IntelliJ web-types are documented. Apache-2.0 code, including applicable license/notice obligations; bundled Lucide icons have a separate ISC license. No paid plan found. Editorial: distinctive for server-rendered Java teams wanting reusable controls without a client-framework migration; ensure the documented Boot/Java version matches your application. Accessibility and CSP descriptions are upstream claims and still require application-specific testing.
