UI Overlay
Pixel-accurate UI review for macOS and Chrome.
Compare live interfaces with design mock overlays
UI Overlay helps designers, front-end engineers, and QA reviewers place local design mock images over live interfaces for visual comparison. Tune opacity, scale, offsets, inversion, lock mode, and click-through mode while keeping the workflow local-first.
Core features
- Import one or more local mock images.
- Adjust opacity, scale, X/Y offsets, fit, centering, and inversion.
- Use click-through mode to review while interacting with the page or app.
- Use the Chrome extension to compare designs directly on normal webpages.
- Use the macOS desktop tool for always-on-top visual comparison workflows.
