Ombrelle.

Ombrelle

Ombrelle is a lightweight Mac utility that automatically dims inactive windows, keeping your attention locked on the task at hand without closing or minimizing anything. Designed as a modern alternative to HazeOver, it runs entirely on your Mac with no account required, delivering distraction-free focus through elegant, invisible automation.

Product Highlights

• Automatic Window Dimming: Instantly dims background windows the moment you switch focus, with zero perceptible delay or flicker
• Customizable Visual Effects: Shape blur, tint, grain, and color intensity to match your preference and environment
• Multi-Display Support: Dim across all screens or leave specific displays untouched for reference work
• One-Click Presets: Switch between Focus (85% dim), Flow, and Evening modes from the menu bar
• App Exclusions: Keep chosen applications permanently bright while everything else fades
• Zero Footprint Design: Lives only in the menu bar with no dock icon, dashboard, or account management
• Lightweight Performance: Uses under 5% CPU and ~200 MB memory, preserving battery life and system speed
• Self-Updating: Installs updates automatically so you never manually manage versions

Use Cases

• Deep Work Sessions: Maintain concentration on a single document, code editor, or design tool while research and communication apps fade into the background
• Multi-Monitor Setups: Keep one display fully lit for reference materials while dimming distractions on your primary workspace
• Evening Computing: Reduce eye strain with darker, warmer tint presets during late-night work sessions
• Presentation Preparation: Focus audience attention on a single window while dimming everything else on screen

Target Audience

Ombrelle is built for Mac users on macOS 14 Sonoma or later who want calmer, more intentional computing without aggressive blocking tools or subscription fees. It serves developers, writers, designers, researchers, and anyone who keeps multiple apps open but needs one window to feel like the only one that matters.
