Chronographs

Sorry I didn’t realize this was in selfhosted, I thought you were looking for an rss reader app not specifically something to talk to commafeed

I’ve been using feeder.co forever which has nested folders, I don’t think I have any three levels deep but I don’t see why it wouldn’t support them.

I think so but it wouldn’t be able to get all the metadata for any new content you add so probably wouldn’t be a great idea
