A look at Ultra's capabilities. A terminal-native code editor that works anywhere — including over SSH.
Before installing Ultra, make sure you have the following:
Ultra is built on Bun for maximum performance. Install from bun.sh
256-color support minimum, true color (24-bit) recommended for best experience.
iTerm2 Kitty Alacritty Windows TerminalmacOS, Linux, or Windows with WSL. Native Windows support coming soon.
Ultra is a proof of concept exploring what a modern, AI-native terminal editor could look like. It is not currently available for download. If there's enough interest, we'll release it publicly.
Launch Ultra in any directory to start editing:
# Open current directory
ultra .
# Open a specific folder
ultra ~/projects/my-app
# Open a specific file
ultra src/index.tsUltra uses familiar keyboard shortcuts. Here are the essentials:
Ultra stores all configuration in ~/.ultra/. Settings use
JSONC format (JSON with comments) for easy customization.
Edit ~/.ultra/settings.jsonc to customize behavior:
{
// Editor settings
"editor.tabSize": 2,
"editor.wordWrap": "on",
"editor.lineNumbers": "on",
"editor.minimap": true,
// Terminal settings
"terminal.scrollback": 1000,
// Theme
"workbench.colorTheme": "Catppuccin Frappé"
}Customize shortcuts in ~/.ultra/keybindings.jsonc:
[
{
"key": "ctrl+s",
"command": "file.save",
"when": "editorFocus"
},
{
"key": "ctrl+k ctrl+c",
"command": "editor.toggleComment",
"when": "editorFocus"
}
]
Ultra supports VS Code-compatible themes. Place theme JSON files in
~/.ultra/themes/ or change the built-in theme in settings.
Built-in themes:
Ultra's built-in Git integration lets you stage, commit, and manage branches without leaving the editor.
Press Ctrl+Shift+G to open the Git panel:
Changes appear in the gutter as you edit:
Ultra includes a full PTY terminal with 24-bit color support, mouse input, and seamless integration with the editor.
The terminal opens in your project root by default. The shell inherits your environment, so all your aliases, functions, and tools work normally.
# Your shell config is automatically sourced
# Example: run tests from the integrated terminal
npm test
# Or use any CLI tool
docker compose up -dCommon issues and their solutions.
Your terminal may not support true color. Check with echo $COLORTERM —
it should show "truecolor" or "24bit". Try iTerm2, Kitty, or Alacritty for full color support.
Make sure the language server is installed and in your PATH. For TypeScript, run
npm i -g typescript-language-server typescript. Check the Problems panel
(Ctrl+Shift+M) for errors.
This can happen with very large projects. Try adding directories to .ultraignore
(same format as .gitignore) to exclude node_modules, build outputs, etc.
Some terminal emulators intercept shortcuts. Check your terminal's settings for conflicts. On macOS Terminal.app, Ctrl+Shift shortcuts often don't work — use iTerm2 instead.
Ultra respects .gitignore by default. If a file is gitignored, it won't appear.
Press Ctrl+Shift+P and run "Toggle Show Ignored Files" to see them.
Sessions are saved to ~/.ultra/sessions/. Make sure this directory is writable.
You can reset sessions by deleting this folder and restarting Ultra.
