kitty
FreeA GPU terminal that can display images inline
A GPL-3.0 terminal with 34,446 stars and GPU rendering. Its graphics protocol was the earliest and remains the most complete, letting you display images and charts inline, and its kitten extensions add plenty more. Powerful, with a correspondingly large configuration surface.
Why we picked it
kitty's distinguishing feature is its graphics protocol: images and charts render inline in the terminal instead of forcing you into another window. 34,446 stars, GPL-3.0, GPU rendering.
Its kitten extension system is equally complete, covering everything from file transfer to diff viewing out of the box.
The cost is a large configuration surface — the first run usually means reading the docs. For something that works out of the box, see Ghostty or Tabby.
