Pure Data (Pd) is a free graphical programming environment for combining media processing in real time. Its patch-based workflow supports audio and graphical processing, and it runs on Windows, macOS, and Linux. Artists use Pd for visual arts, theatre, dance, audio, installations, performance, and media art. It can also control hardware and electronics or develop interfaces for other programs. Pd's built-in Deken package manager installs external libraries that extend its functionality. Deken is mainly intended for Pd vanilla, though some other Pd flavors, including Plug Data, can use it. Package listings specify availability for macOS, Linux, Windows, or source compilation, and some packages are limited to particular architectures. Users can find a library or object and install a downloaded DEK package through Pd's Find externals tool. The listed plan is free; no paid plans or usage limits are stated.
