No, the source code is licensed under AGPL. The business model is to eventually sell licenses to companies selling proprietary products/services.

Edit: I forgot to say that it's thanks to donations (a big thank you to Zotero) that I could have bought a Mac and paid the development license

It's interesting you mention Zotero, I use Zotero all the time especially for university work. It has similar functionality in that it saves webpages. Is there any overlap with Singlefile? Or might the integrate?

I confirm they use SingleFile under the hood to save snapshots :)

That's excellent, I do use Singlefile as well but Zotero offer the database/citation functionality on top. Brilliant extension though, after ublock it's probably number 2 install for me.

Don't worry, even if you only use Zotero, I wouldn't blame you. It's a very good product. Thanks a lot for your support :)
