Sandy

Visual UI layout prototyping tool

NeuLogic Sandy is a lightweight UI layout design tool that lets you quickly prototype application interfaces by placing, moving, and resizing common UI elements on a configurable canvas — no coding required.

Whether you're sketching a new dialog, planning a settings screen, or communicating a layout idea to a developer, Sandy gives you a clean, distraction-free sandbox to work in.

Key Features:
  • 14 UI Element Types – Button, Label, Input Field, Checkbox, Radio Button, ComboBox, GroupBox, TextEdit, ProgressBar, Slider, SpinBox, Frame, Hamburger Btn, and Kebab Btn
  • Smart Snap Alignment – Orange guide lines appear automatically when element edges or centers align, letting you place elements precisely without manual coordinate entry
  • Overlap Prevention – Elements cannot overlap each other; Sandy finds an open position automatically
  • Configurable Canvas – Set any width and height, choose a corner radius, and toggle a Windows-style title bar on or off
  • Per-Element Properties – Control exact position, size, label text, and corner radius for every element with live preview
  • Label Auto-Sizing – Label, Checkbox, and Radio Button elements automatically resize their width to fit the text you type
  • Undo / Redo – 999-step undo and redo history covering all committed actions
  • Duplicate and Delete – Quickly clone any element or remove it with a single action
  • Full Keyboard Shortcuts – Add any element type with Alt+letter, duplicate with Ctrl+D, delete with Del, open properties with Ctrl+P, undo with Ctrl+Z, redo with Ctrl+Y
  • Container Elements – Frame and GroupBox stack behind other elements to visually group related controls
  • No Internet Connection Required – Works entirely offline
