Frogmouth is a Markdown viewer / browser for your terminal, built with Textual.

Frogmouth can open *.md files locally or via a URL. There is a familiar browser-like navigation stack, history, bookmarks, and table of contents.

Frogmouth runs on Linux, macOS, and Windows. Frogmouth requires Python 3.8 or above.

The easiest way to install Frogmouth is with pipx (particularly if you aren't a Python developer).

pipx install frogmouth

You can also install Frogmouth with pip:

pip install frogmouth

On systems using Homebrew, you can tap into the Textualize tap and install Frogmouth with brew:

brew tap textualize/homebrew
brew install frogmouth

Whichever method you use, you should have a frogmouth command on your path.

Enter frogmouth at the prompt to run the app, optionally followed by a path to a Markdown file:

frogmouth README.md

You can navigate with the mouse or the keyboard. Use tab and shift+tab to navigate between the various controls on screen.

You can load README files direct from GitHub repositories with the gh command. Use the following syntax:

frogmouth gh textualize/textual

This also works with the address bar in the app. See the help (F1) in the app for details.
