TUT(1) - Terminal User Interface Browser
NAME
tut - vim-style terminal web browser
SYNOPSIS
tut [URL]
tut -h | --help
DESCRIPTION
tut is a text-mode web browser designed for comfortable reading in the terminal. It extracts and displays the textual content of web pages with a clean, centered layout optimized for reading, while providing vim-style keyboard navigation.
The browser does not execute JavaScript or display images. It is designed for reading static HTML content, documentation, and text-heavy websites.
OPTIONS
URL Open the specified URL on startup. If omitted, displays the built-in help page.
-h, --help Display usage information and exit.
KEYBINDINGS
tut uses vim-style keybindings throughout.
Navigation
j, Down Scroll down one line.
k, Up Scroll up one line.
Ctrl-D, Space Scroll down one page.
Ctrl-U, b Scroll up one page.
gg Jump to top of page.
G Jump to bottom of page.
[count]G Jump to line count (e.g., 50G jumps to line 50).
[count]j, [count]k Scroll down/up count lines (e.g., 5j scrolls down 5 lines).
Link Navigation
Tab Move to next link.
Shift-Tab, T Move to previous link.
Enter Follow current link.
h, Left Go back in history.
l, Right Go forward in history.
Search
/ Start search. Enter search term and press Enter.
n Jump to next search match.
N Jump to previous search match.
Commands
Press : to enter command mode. Available commands:
:q, :quit Quit the browser.
:o URL, :open URL Open URL.
:r, :refresh Reload current page.
:h, :help Display help page.
**:**number Jump to line number.
Other
r Reload current page.
q Quit the browser.
? Display help page.
ESC Cancel command or search input.
LIMITATIONS
tut does not execute JavaScript. Modern single-page applications (SPAs) built with React, Vue, Angular, or similar frameworks will not work correctly, as they require JavaScript to render content.
To determine if a site will work with tut, use:
curl https://example.com | less
If you can see the actual content in the HTML source, the site will work. If you only see JavaScript code or empty div elements, it will not.
Additionally:
- No image display
- No CSS layout support
- No form submission
- No cookie or session management
- No AJAX or dynamic content loading

INSTALLATION
From Source
macOS (Homebrew):
brew install cmake ncurses curl
mkdir -p build && cd build
cmake ..
cmake --build .
sudo install -m 755 tut /usr/local/bin/
Linux (Debian/Ubuntu):
sudo apt-get install cmake libncursesw5-dev libcurl4-openssl-dev
mkdir -p build && cd build
cmake ..
cmake --build .
sudo install -m 755 tut /usr/local/bin/
Linux (Fedora/RHEL):
sudo dnf install cmake gcc-c++ ncurses-devel libcurl-devel
mkdir -p build && cd build
cmake ..
cmake --build .
sudo install -m 755 tut /usr/local/bin/
Using Makefile
make
sudo make install
FILES
No configuration files are used. The browser is stateless and does not store history, cookies, or cache.
ENVIRONMENT
tut respects the following environment variables:
TERM Terminal type. Must support basic cursor movement and colors.
LINES, COLUMNS Terminal size. Automatically detected via ncurses.
EXIT STATUS
0 Success.
1 Error occurred (e.g., invalid URL, network error, ncurses initialization failure).
PHILOSOPHY
tut follows the Unix philosophy:
- Do one thing well: display and navigate text content from the web.
- Work with other programs: output can be piped, URLs can come from stdin.
- Simple and minimal: no configuration files, no persistent state.
- Text-focused: everything is text, processed and displayed cleanly.
The design emphasizes keyboard efficiency, clean output, and staying out of your way.
