Monolith captures web pages exactly as they appear online and saves them as single, self-contained HTML files. Unlike conventional "Save page as" functions, monolith embeds all assets—CSS, images, and JavaScript—directly into one file using data URLs, eliminating the need for external resources or network connections.

Key capabilities include:

Complete asset bundling: CSS, images, fonts, and scripts all embedded in a single HTML5 document
Selective asset exclusion: Remove scripts, images, videos, audio, fonts, or frames as needed
Domain control: Whitelist or blacklist specific domains for asset retrieval
Cookie support: Authenticate requests using stored cookies
Format flexibility: Save as HTML or MHTML format
Dynamic content handling: Pre-process JavaScript-heavy sites using Chromium before capture
Cross-platform: Available via Cargo, Homebrew, Chocolatey, and numerous package managers

Unlike wget-based approaches, monolith's data URL embedding ensures saved pages render identically to their online versions, even offline. Perfect for researchers, data archivists, and anyone needing to preserve web content exactly as it appeared. Configure network timeouts, custom user agents, and basic authentication to handle various scenarios. The tool runs from the command line and accepts input from URLs or stdin, making it ideal for automation and batch processing workflows.
