Überblick
Renders an animated, color, ANSI-text loop of the Poptart Cat
Verlauf
nyancat is the terminal version of the Nyan Cat / Poptart Cat animation, rendered with ANSI escape sequences and usable either as a standalone program or as a telnet-service payload. The upstream repository describes it as the source for the Debian nyancat package.
The klange/nyancat repository was created on 2011-11-30, during the original wave of Nyan Cat terminal jokes. The README credits prguitarman for the original animation and licenses the code under the NCSA license.
Unlike many joke programs, nyancat became widely packaged. Its README lists availability in Arch, Debian, Fedora, Gentoo, Mandriva, Ubuntu, FreeBSD, OpenBSD, and NetBSD, and Homebrew reported stable version 1.5.2 with 988 installs over the 365-day analytics window queried on 2026-07-01.
Users run nyancat directly for a terminal animation, build it with make for source installs, or run nyancat -t from an inetd-style service to expose a telnet server. The public nyancat.dakko.us telnet server page says the original hosted service was shut down because of bandwidth limits, leaving mirrors and local installs as the practical paths.
nyancat is a canonical example of a harmless meme becoming a real distro package. It is useful for testing ANSI color support, terminal animation behavior, package-manager reach, and whether a packaging ecosystem has room for software whose value is delight rather than productivity.
