Fatdog64 Linux is a lightweight, full-featured 64-bit distribution inspired by Puppy Linux but developed independently for modern systems. With a download size of just ~600MB, it delivers a complete desktop experience ready out of the box. Despite its small footprint, Fatdog64 includes a rich set of everyday tools like Seamonkey browser/mail, VLC, LibreOffice, GIMP, and more. It supports remote access via RDP, VNC, and SSH, along with printing, scanning, and media editing tools.
Fatdog runs efficiently on most x86_64 systems made after 2008, requiring only 1GB RAM to start.
Applications are available in two formats: TXZ (traditional compressed packages) and SFS (squashfs-based modules). TXZ files install like DEB or RPM, while SFS modules can be loaded/unloaded on demand. The system is designed for performance, portability, and minimal resource usage. Ideal for advanced users, minimalists, and those reviving older hardware.
Fatdog64 stays true to the Puppy Linux ethos—small, fast, and powerfully simple.
