Quicksilver: Free and Open-Source Utility for macOS

Quicksilver is a free and open-source utility application for macOS that provides quick access to files, contacts, applications and other system tools through an intuitive interface. It allows searching and launching apps and files quickly using abbreviations and keywords.

What is Quicksilver?

Quicksilver is a fast and intuitive utility application for macOS. Originally developed in 2002, it aims to enhance productivity by giving quick access to files, applications, contacts and other system functionality.

Some key features of Quicksilver include:

  • Typing abbreviations or keywords to quickly launch applications
  • Browsing the filesystem and opening files rapidly
  • Lookup and access contacts information
  • Perform calculations and unit conversions
  • Control iTunes and much more without switching applications

The interface uses a hotkey to bring up a small search window, where typing keywords filters the catalog of available actions. Results appear ranked according to the current context and user preferences through a continually updated learning process. This allows launching frequent tasks very rapidly with just a couple keystrokes.

Quicksilver also offers a plug-in architecture so developers can extend its capabilities even further. There are plug-ins available to integrate with applications like Firefox, Spotlight, Growl and many others.

Originally a commercial product, Quicksilver went open source in 2006 and continues to be developed by an active community of contributors. It emphasizes flexibility, breadth of capabilities and speed through smart adaptive learning.
