I researched various archiving alternatives for something I needed recently. I subscribe to a paid Substack for an educational course that will end mid-year, and I want to archive the course posts before it ends (the course provider has even recommended people end their Substack subscription after it ends).<p>For this purpose, I found the SingleFile browser extension to be the best fit. It's a browser extension, so paywall cookies are already present, and I just manually archive the previous week's content, <i>after</i> the discussion phase has concluded. It creates a single self-contained file with all images and comments, etc., but all non-page-local links still resolve externally (which is as-desired, for my use case). It can be configured to auto-generate a convenient filename, and to use self-extracting compression.<p>I preferred this to an automated process based on, e.g., RSS, because I can ensure the archive occurs <i>after</i> all the useful course comments back-and-forth has concluded, and it's trivial to set up and use.
