Here's a small list of programs which I use as alternatives to classic UNIX-and-related tools. Lesser-known first to keep the list interesting:

• LeftWM - a window manager
• Helix - a text editor
• Zellij - tmux alternative, batteries included
• Nu - cross-platform shell with a fresh approach to streams & redirections
• Zola - a static site generator, which powers this website
• Paru - AUR helper for all Arch folks
• Neovide - neovim client with eye-candy animations
• Caddy - a web server with automatic HTTPs and refreshingly simple configuration
• Alacritty - a terminal emulator
• Wezterm - another terminal emulator
• Zoxide - a smarter cd command
• Fzf - Fuzzy finder for pretty much everything
• fd - unix find but actually usable without having to read man each time
• duf - like df but easier to read
• Popsicle - USB File Flasher

I encourage you to try them out, perhaps some of them will improve your workflow or at least be fun play with.
