Fusion Link Launcher

A lightweight macOS menu bar utility that watches your clipboard for URLs and lets you instantly open them in any installed browser — with one click.

Why

When you copy a URL on macOS, opening it in a browser other than your default requires manual effort: paste, switch app, navigate. Fusion Link Launcher removes that friction entirely.

Copy a URL → pick a browser → done.

Features

• Sits silently in the menu bar with zero Dock presence
• Detects copied URLs automatically (polls clipboard every 0.5s)
• Dynamically discovers all installed browsers — Safari, Chrome, Brave, Firefox, Arc, Edge, Vivaldi, and any other app that can open URLs
• Shows a non-intrusive floating popup in the top-right corner, auto-dismisses after 8 seconds
• Cooldown deduplication — won't re-prompt for the same URL within a configurable window
• Optional URL normalization (adds https:// to bare domains like github.com)
• Launch at login support via SMAppService
• Settings panel for all preferences

Requirements

• macOS 13 Ventura or later
• Xcode 15+ (to build from source)

Privacy

All clipboard processing happens locally on your device. No data is ever sent to any server, logged to disk, or shared with any third party. URL history is stored only in memory and cleared on quit (unless you enable persistent history in a future release).
