kitty is a fast, featureful, GPU based terminal emulator.

Highlights:

• Offloads rendering to the GPU for lower system load and buttery smooth scrolling. Uses threaded rendering to minimize input latency
• Supports all modern terminal features: graphics (images), unicode, true-color, OpenType ligatures, mouse protocol, focus tracking, bracketed paste and several new terminal protocol extensions
• Supports tiling multiple terminal windows side by side in different layouts without needing to use an extra program like tmux
• Can be controlled from scripts or the shell prompt, even over SSH
• Has a framework for Kittens, small terminal programs that can be used to extend kitty's functionality. For example, they are used for Unicode input, Hints and Side-by-side diff
• Supports startup sessions which allow you to specify the window/tab layout, working directories and programs to run on startup
• Cross-platform: kitty works on Linux and macOS, but because it uses only OpenGL for rendering, it should be trivial to port to other Unix-like platforms
• Allows you to open the scrollback buffer in a separate window using arbitrary programs of your choice. This is useful for browsing the history comfortably in a pager or editor
• Has multiple copy/paste buffers, like vim
