GTFO by Apollyon

GTFO is a compact browser toolkit for inspecting and working with web pages faster.

It includes a powerful page grabber that can collect URLs, page sources, scripts, stylesheets, comments, and image references from the current page. The grabber opens in a dedicated report view with searchable source output, selectable matches, syntax highlighting, prettify support, and export options.

GTFO also includes quick utilities for restoring right-click behavior, revealing hidden page elements, and opening settings for tool preferences.

Built for developers, researchers, and power users who want a fast way to inspect what a page contains without jumping between multiple browser tools.
