Arcadia Studio is a Windows app for designing Minecraft screens (menus, dashboards, control panels and shops) by dragging controls onto a canvas. You connect buttons to actions or JavaScript, preview everything on your desktop, and export a mod JAR that works in Minecraft Java Edition 1.21.1 with NeoForge. There's no Java code to write and no Minecraft restart needed while designing.
