I was setting up a RSS reader with a bunch of webcomics but I immediately ran into the problem of some being on Instagram and I would like to have some way to handle that without having to use instagram. After some googling I found a bunch of links to abandoned or broken projects with documentation I did not understand.
Any help or suggestions would be appreciated. I am quite the beginner tough, I have a truenas running on an old computer and a raspberry pi in a desk drawer so that the general competence I am working with.
I have personally been very happy with FreshRSS. Nowadays I use Nextcloud News (just a Nextcloud) app for it. So if you already have Nextcloud you don’t even need to selfhost something extra.
They both have WebApps. FreshRSS has a few themes to fit your taste and Nextcloud News will obviously follow your Nextcloud theming.
As far as apps go, FreshRSS has (probably) more than Nextcloud News. I personally like Feeder (only in PlayStore but worth it imo). For Nextcloud there is an App with the same name. Also good imo, but FreshRSS/Feeder has more customization options.
EDIT: Here is a nice list of a lot of Feed Readers: https://github.com/awesome-selfhosted/awesome-selfhosted#feed-readers
