Helios

A native macOS launcher built with Swift and AppKit.

Helios lives in your menu bar and activates with a global hotkey. Type to search across apps, bookmarks, quick links, and more — results appear instantly as you type.

Features

• App launcher — find and open applications
• Calculator — evaluate math expressions inline
• Date & time — timezone lookups, time conversions, relative dates, countdowns
• Firefox bookmarks — search your bookmarks directly
• Quick links — keyword-triggered URL shortcuts (e.g. gh swift opens a GitHub search)
