> The idea that it must be more accessible because it’s confined to a mono space typeface and communicates state mostly by changing the foreground and background color of the text it renders makes no sense to me.

That's not why. It's because TUI apps have to be designed around the strong possibility that a mouse isn't even available.

Also in a TUI you never ever have that issue that some text isn't copy/pastable like some dialogue boxes, in which case the screen reader might have issues picking it up too.

And in a TUI you don't have to deal with that window management crap. Moving stuff around because something else is on top. Everything happens within that little square.

May I present OpenCode, which somehow managed to break copy from terminal: https://github.com/anomalyco/opencode/issues/4283


Not requiring a mouse isn’t a magic pathway to ‘accessibility’ though. The fact that something can be used with a keyboard does not obviate developers from the need to consider other aspects of accessibility.

Also: when I copy paste out of an application I don’t want a bunch of spurious chrome glyphs and newlines - copying just the text contents of a TUI scrollable text field isn’t trivial and isn’t always guaranteed to work

Telle that to Anthropic, as Claude code doesn't let me copy any text from its TUI.
