Readeck saves a page as a zip file. It's not hard to open from the command line or file manager, just unzip and launch the index.html in the web browser. But it strips out a lot of detail. Zipping it also means that it's hard to deduplicate. I use WebScrapBook and run rdfind to hardlink all the identical files.
