Fastfetch vs htop

Fastfetch is a free, open-source command-line tool that displays operating system, hardware, and software details in a terminal alongside customizable logos. Its more than 75 modules cover information such as CPU, GPU, memory, disks, battery, TPM, audio, and Wi-Fi. It can display ASCII logos or render images through Kitty, Sixel, iTerm2, or Chafa protocols. Configuration uses JSONC, with an official schema for editor autocomplete and validation. The maker lists native support for Windows, macOS, Linux, BSD, and Android through Termux, and installation options including winget, Scoop, Homebrew, MacPorts, APT, Pacman, DNF, FreeBSD pkg, and Termux. Fastfetch can be integrated with Bash, Zsh, Fish, PowerShell, and Nushell startup setups and is compatible with Starship and Oh My Posh. Sample configurations can query music services for media information. The maker highlights terminal startup greetings, hardware auditing and diagnostics, and desktop screenshot showcases. It warns that unconditional output from a shell startup file can disrupt SCP, SFTP, and other non-interactive shell operations.

htop is a free, text-mode interactive process viewer for Linux and macOS. It runs in console or X terminals and requires ncurses, offering a command-line interface for watching and managing running processes. Current releases also list FreeBSD, NetBSD, OpenBSD, DragonFly BSD, and Solaris as supported systems. The project, founded in 2004, is distributed as source code on GitHub and as pre-compiled packages from operating-system distributors, with installation examples for Debian, Fedora, Gentoo, and Arch Linux; Homebrew includes it for macOS. Its display can show Unicode Braille graphs and a Unicode tree view, including visual support for large processor counts. Users can set I/O scheduling priority and CPU affinity, choose dark or light terminal themes, and customize header meters. The memory percentage covers process-used memory; htop does not provide a per-process SWAP column.
