Alignly

Alignly is a high-performance Chrome Extension that brings Figma-style smart alignment guidelines, snap coordinates, and precise spacing labels to Excalidraw. It runs directly in the browser with zero layout lag, matching your moves in real-time. Key Features 1. Edge-to-Edge Alignment Guidelines — Dashed red lines appear instantly when element boundaries align horizontally or vertically. 2. Center-to-Center Alignment Guidelines — Dashed blue lines indicate when the horizontal or vertical center axes of multiple shapes are aligned. 3. Dynamic Spacing Labels — Displays precise real-time pixel distances between aligned shapes. 4. Multi-Select Snapping — Snap and align multiple elements at once; the bounding box of your selection is calculated and snapped as a group. 5. Tactical Keyboard Nudging — Moving shapes with arrow keys displays visual guidelines without locking them physically, allowing for fine-grained manual adjustments. 6. Integrated Customization Popup — Adjust snap threshold sensitivity (3px to 16px), line width, line paddings, and toggle guide types on the fly. 7. Theme-Aware Styling — Colors automatically adjust for vivid contrast in both Light and Dark modes.
