A macOS menu bar app for switching windows with fuzzy search. Hit a hotkey, type a few characters, and jump to any window instantly. Sublime Text-inspired fuzzy matching means you don't need to type exact names.

Features

• Configurable global hotkey (default: Option+Shift+Space)
• Sublime Text-inspired fuzzy matching algorithm
• Multi-term search — type multiple words in any order
• Keyboard navigation with arrow keys
• Full VoiceOver accessibility support
• Lightweight menu bar app with minimal resource usage

Installation

brew tap intelligrit/ffwf
brew install --cask ffwf

Requires macOS 14.0+. Also available to build from source.

Architecture

Built with Swift and SwiftUI. Key components:

• WindowManager — Concurrent window enumeration via Accessibility API
• FuzzyMatcher — Scoring algorithm with pre-lowercased strings for performance
• HotkeyRecorder — Customizable global keyboard shortcut registration

Performance optimizations include icon caching, event-driven updates, and pre-computed lowercase comparisons.
