I just use konsole , which is the default terminal emulator for KDE. I don’t need anything fancy, just something basic to run commands, updates, a few scripts, etc.

I primarily use Alacritty. I spend quite a lot of time running things that produce ludicrous amounts of output (eg. compiling Android from source). Out of 10 or so terminal emulators I’ve tested earlier this year, it was the only one that didn’t use 100% CPU displaying all that output, staying in the low single digits.

I’d prefer to use Wezterm because I like its lua configuration system and the builtin pane splitting, but with my workload, I still run into issues where its CPU usage shoots to 100% and becomes non-responsive for a while. (That said, it’s already a lot better than before. I try to report any issues I can reliably reproduce and Wez has been wonderful about fixing them.)

I use foot together with foot-server. The client opens in less than a millisecond, and I usually have tens of terminal windows open at the same time. Tabbing comes from the window manager.
