I forget why I didn't like Zotero - I am using iLibrarian [0]. It is positioned as a SaaS, but the source is available and you can host it yourself. But I can't speak to how it compares to other software as I am not continually using it. It seems I just like collecting scientific papers rather than actually reading them.... Maybe if I live to 150 will I manage to read them all.
Oh damn. It looks extremely close to what I want (It's responsive and the PDF UI might even work on my e-reader), but it doesn't seem to support importing web pages?!?!?!?!?!?!?!?!?!?!?!?!?!?!
What a massive and disappointing oversight. Otherwise I could've seen it becoming my new research manager.
It extracts the metadata, but not the body, yes. Retrieved websites are generally frowned upon in my field (medicine, virology), and that's why I never really needed this. We're pandoc-ing our internal MD files to PDF and attach them to the relevant HTML pages, which makes this somewhat a crutch but circumvents the "9 out of ten reviewers hate websites" problem.
I print the webpage to a PDF and store it that way, then fix up the metadata as I see fit. And that is a good feature - make a request on the Github repo and see if the lead developer responds.

And I wholeheartedly second the fact Mendeley is Evil. I got sick of the bugs.
