Quicksilver is a utility app for macOS. Originally developed as proprietary freeware by Nicholas Jitkoff of Blacktree, Inc., it is now an open-source project hosted on GitHub.
Quicksilver is essentially a graphical shell for the macOS operating system, allowing users to use the keyboard to rapidly perform tasks such as launching other apps, manipulating files, or sending e-mail. Since its first release in 2003, many of its features have subsequently been integrated into the modern macOS system feature, Spotlight. It is similar to the macOS applications LaunchBar and Alfred, but uses a different interaction paradigm. Because of its flexible interface and extensibility, Quicksilver has been called one of the top productivity applications on the Mac.
