This list is generated from what actually ships: every entry below is a recipe inside the application, not a claim on a page.

Shapes of page, anywhere
These are not places but kinds of page. They work on sites nobody wrote a recipe for, which is most of the web.
Forum thread
Gallery or album
Just this page
The whole site, or a part of it
And what the engines cover
Video and media sites are handled by the yt-dlp and gallery-dl plugins, which between them recognise thousands of sites. They ship with the application and update on their own schedule, so their coverage is theirs to state rather than ours to copy.
A site missing that you need? Tell us — a recipe is a small file, and site requests are how the list grew.
