Nitty is a software-rendered terminal emulator written in Nim. It was written in ~4 days and has ~900 lines of code (if you exclude the windowing code).

It uses libvterm for handling VT output and acting upon it.

You can join the Discord server here for help with Nitty, or to follow its development.

• Runs most terminal apps fine (keyword: most)
  • In fact, this README was written entirely in Neovim running inside Nitty!
• Color rendering support
• Config file (~/.config/nitty/config.toml)
• Ctrl+Plus and Ctrl+Minus to increase/decrease font size
• Okay performance-wise, with room for optimizations.
• Tab completions in shells work

• Cursor rendering
• Input improvements (repeat key events, mostly)
• GPU acceleration via Boxy
• Packaging for distros
• Better damage tracking (currently, it forces the compositor to reblit the entire surface every frame)

Here's a basic config for Nitty:

[appearance]
background = "#5050500A"

[font]
name = "JetBrains Mono"
size = 24.0

[user]
shell = "zsh"

Nitty can be built using Neo. After installing Neo, you can run the following command to compile Nitty:

$ neo install
