iTerm2: Pricing, Features & Alternatives

iTerm2 has been the first thing many developers install on a new Mac for well over a decade. Split panes, a hotkey window, search, autocomplete from history, triggers that react to output, shell integration that marks each command, and a native tmux mode (`tmux -CC`) that turns remote tmux sessions into real macOS tabs and windows. It is free, GPL-licensed, and funded by donations. It is macOS only, and its preferences window is famously deep, which is both the appeal and the complaint.
