I’m a librarian who does a fair bit with web archives. the short 
version is this:

replayweb.page will work to ‘play’ a web archive (warc/wacz). there 
is a desktop application (electron) that you can grab from github. I 
find it better than trying to load something like that into firefox. I 
don’t know what the policy is about adding an electron app into 
macports is but speaking as a maintainer for an electron app on a linux 
distro...I’d personally avoid it.

py-wacz is great for converting warc files into wacz. the primary 
difference is that the later are compressed. That’s the primary 
function it has.

One thing for creating warc files in Macports is wget which works with 
something like: wget -pkrm --warc-cdx --warc-file=foo -e robots=off 
[https://foo.org](https://foo.org). I did a write up about it back in 

I hope that helps a little bit.
