Cons: no built-in way to preview images, it's handling of background images can be wonky. It has full true color support, a dropdown hotkey, transparency, background image, panes, tabs, shell integration. So here are a few terminals that are probably closest to iterm2 in terms of feature parity: Qterminal I cannot find a single linux terminal that completely matches this feature set (much less all the ones I didn't mention) but there are linux terminals that come pretty darn close, and can do things that iterm2 can't do (like set per window/pane background images). I haven't even come close to listing them all, although these are the ones I use/care about the most.
MAC OS TERMINAL EMULATOR SKIN
The stock KDE terminal is a solid choice and in addition to a rich feature set it's the only terminal I know of that comes out of box with that recent MacOS-ish translucency blur onion skin effect (a.k.a. I'm not wild about the choice of configuring through dconf rather than just having a text file in $HOME/.config, but not the end of the world. Not on par with iTerm2 in terms of feature set, but a very solid choice for a daily driver.
MAC OS TERMINAL EMULATOR DRIVER
Tilixįantastic and polished terminal emulator, been my daily driver for a while now.
It's a newer project but this may be the iTerm2 killer. If you're a ricer, this is the terminal emulator for you. The only other thing I want is a hotkey dropdown terminal, not the end of the world. One feature I miss is profiles, but you can always have multiple config files (author made the interesting choice of using Lua rather than ini/toml/yaml/json for the config file). Has GPU acceleration, built in multiplexer (tabs and splits), ligature support, built in imgcat support, background images, transparency, shell integration, almost everything one could want. My current picks for my favorite Linux iTerm2 replacements are, in no particular order: Wezterm While I in general prefer GTK applications in terminal emulators the reigning champ Qt is being overtaken not by them but by projects eschewing traditional GUI toolkits entirely!
