4 shadow presets
Whisper, Gentle, Dappled, and Deep — handcrafted overlays for different moods.
Adjustable opacity
Fine-tune intensity from 5% to 80% with a simple slider.
Global defaults
Pick a shadow and opacity once and they apply to every site you visit.
Zero flicker
Overlay appears before the page paints. No flash, no layout shift.
Per-site overrides
Customize or disable the overlay on a single site without touching your defaults. Subdomains stay independent, so an app under
app.example.com isn’t affected by the marketing site.Fully private
