I host https://proxigram.kyun.li and it is currently down, will work again soon :)

EDIT: Instance is working again

The RSS feature is amazing, i wanted to do something like that with RSS Bridge, but it looks like both Instagram and Facebook are doing their best to block exactly these kind of things, so it works half of the times and it needs to be fixed quite often, i think now it doesn't work very well either... Also it is very complicated to be set up if you don't know a bit of PHP. Of course i'm willing to learn but all this blocking that projects like this (see Barinsta or Bibliogram) get is really discouraging. I think Meta content is probably one of the worst to scrape.

Regarding Proxygram: for now it works, i'm using a public istance to grab some RSS feeds, if it proves to be reliable i will be happy to host my own istance as well, if possible :) It's sometimes slow to grab data (i guess because sessions get easily blocked/limited, getting error 500) but not really a problem as i just want to see new events every couple of days, one issue tho is that the RSS doesn't show all the posts (only showing the last three of them), which can be annoying as you may lose something if you don't see it and save it.

EDIT: It actually does get other posts as well, just reaaally slowly, meaning that if you follow really large accounts in a week or so you can find your feed full of older posts marked as unread.

Anyway thanks to whoever is making the hard job of building/owning an instagram scraper, I really know it can be tough.
