LayerX
A macOS app for displaying transparent images on screen with intuitive controls for designers and developers.
What is LayerX?
LayerX is a macOS application that displays transparent images directly on your screen. It solves the problem of needing to visualize design assets, references, or templates in context without switching between applications or dealing with complex overlay tools.
UI/UX designers, frontend developers, and digital content creators who need to overlay reference images or design mockups while working in other applications.
Developers choose LayerX for its simplicity, keyboard-driven workflow, and focus on doing one thing well—providing a lightweight, always-on-top image overlay without the bloat of full-featured design software.
Overview
An intuitive app to display transparent images on screen.
Use Cases
Best For
- Overlaying design mockups while coding implementations
- Comparing website designs against live versions
- Keeping reference images visible while working in other apps
- Creating temporary screen annotations or markers
- Visualizing transparent PNG assets in context
- Quick image paste-and-display workflows for designers
Not Ideal For
- Cross-platform teams requiring Windows or Linux compatibility
- Users needing advanced image editing like layers, filters, or annotations
- Workflows that involve batch processing or scripting for overlays
- Collaborative projects where multiple users need to interact with overlays simultaneously
Pros & Cons
Pros
The README lists extensive keyboard shortcuts for scaling, moving, and transparency adjustment, enabling rapid operations without mouse reliance.
Focuses solely on essential overlay tools, avoiding bloat as emphasized in the app's philosophy of simplicity.
Features like lock images (⌘ L), always-on-top windows, and multi-space support ensure overlays remain visible across workspaces.
Supports drag-and-drop and clipboard paste (⌘ V) for instant image loading, streamlining setup from the README examples.
Cons
Only available for macOS, excluding Windows and Linux users, which restricts utility in mixed-device environments.
Lacks advanced tools like image rotation, freeform scaling, or annotations, limiting use to basic overlay tasks beyond the README's scope.
With the last update dated 2017, it may not be optimized for newer macOS versions or receive ongoing support and bug fixes.
No scripting APIs or batch operations mentioned, making it inefficient for repetitive or automated overlay workflows.
