A data hoarder’s dream come true: bundle any web page into a single HTML file. You can finally replace that gazillion of open tabs with a gazillion of .html files stored somewhere on your precious little drive.

Unlike the conventional “Save page as”, monolith not only saves the target document, it embeds CSS, image, and JavaScript assets all at once, producing a single HTML5 document that is a joy to store and share.

If compared to saving websites with wget -mpk, this tool embeds all assets as data URLs and therefore lets browsers render the saved page exactly the way it was on the Internet, even when no network connection is available.

monolith -I -B -d .googleusercontent.com -d googleanalytics.com -d .google.com https://example.com -o example-no-ads.html

Monolith doesn't feature a JavaScript engine, hence websites that retrieve and display data after initial load may require usage of additional tools.

For example, Chromium (Chrome) can be used to act as a pre-processor for such pages:

chromium --headless --window-size=1920,1080 --run-all-compositor-stages-before-draw --virtual-time-budget=9000 --incognito --dump-dom https://github.com | monolith - -I -b https://github.com -o github.html

Please set https_proxy, http_proxy, and no_proxy environment variables.

Please open an issue if something is wrong, that helps make this project better.
