Pure Data vs SuperCollider

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.

SuperCollider is a free platform for audio synthesis and algorithmic composition for musicians, artists, and researchers working with sound. Its components include scsynth, a real-time audio server with hundreds of unit generators for analysis, synthesis, and processing; sclang, its language; and scide, its development environment. The alternative supernova server supports multithreaded operation. A client/server design lets multiple clients control the server, with client implementations in Python, JavaScript, Haskell, and Scala as well as native sclang. sclang includes Quarks for managing packages with classes, extension methods, documentation, and UGens. Third-party plugins can connect through C and C++ APIs. SuperCollider runs on Windows, macOS, and Linux, and can also be used on Raspberry Pi, Bela, and in browsers through WebAssembly. The project lists version 3.14.1 as its current release. Its downloads page lists macOS 11 or later, Windows 10 and 11, and Linux builds requiring gcc 9 or later. It is free software under version 3 of the GNU General Public License.
