I find SingleFile [0] to be a much more robust version of this. It strips out all the JavaScript too, but also packs everything into a single HTML file that is easy to transfer. Binary assets (like web fonts and images) are packed as base64 strings. They also offer a CLI powered by Puppeteer.

What's the difference with, any webbrowser on a computer, File -> Save as ?

Save As works fine for simple websites with static content.

Let's say you have a site that fetches content from a database. If you Save As, then at best you'll get a local copy of an HTML page with JS that loads the content from the same remote database. It might not work (since the local copy has a different origin), or if it does, it requires you to be online, which defeats half of the purpose.

What this project, and SingleFile, both do is save a snapshot of what the rendered page actually looks like at that moment in time. The scripts are stripped out so it runs locally and has no external dependencies.

Earlier quoted context omitted.

Usually JavaScript is blocked when you load pages that way.

Since when? You won't be able to make HTTP requests to localhost, as it'd be a different Origin, but I don't think any mainstream browser blocks JS outright when you use file:// to load and view HTML files.

Somewhere around 2019, each document loaded from file:// became its own origin in Firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=1500453 (I didn't check when this happened in Chromium)

I was intrigued to see how the demo GIF in the README was generated: https://github.com/tamnd/kage/blob/01e75b87ecc893bbba7943c63... Turns out it's using another project by the same author: https://github.com/tamnd/ascii-gif The script used for the demo is at https://github.com/tamnd/kage/blob/01e75b87ecc893bbba7943c63... and has a comment showing how to run it: ascii-gif render docs/demo/kage.tape -o docs/static/dem…

FYI, on other platforms (Windows/MacOS), LiceCAP is a fantastic tool to record screen into compact GIFs by the author of Winamp and Reaper DAW:

I've accumulated a bunch of old website archives over the years. The funny thing is the ugly HTML dumps have been more useful than the "perfect" archive.

It's one of the reasons I've become a bigger fan of RSS over time. A feed from 10-ish years ago is often more usable today than a carefully preserved (application) website.

I am quite familiar with this and it is factually false

Js modules don’t work on file urls (classic js does).

Love love love SingleFile too. The FF extension works pretty well for a clean save. That said, Kage looks promising if OP can combine SingleFile reproduction quality with the HTTPTrack spidering approach. SPA's are kinda tricky with archiving and do wonder how well Kage would handle that

I've seen the option in IE- .mhtml.

For some reason it displays in IE better but I don't recall seeing this option in chrome of Firefox recently..
