There was bibliogram (web) which I’ve used a couple of times, but it’s now discontinued.
Your best bet here would be using instagram web as a webapp with a bunch of addons limiting their tracking. I dunno if there are some limitation on the instagram website, I don’t use instagram at all.
By looking up on f-droid there is “barinsta” which received a cease and desist letter from a law firm representing Facebook. Maybe you can find an active fork of it.
If you find something, please update us. There could be someone else in your same condition.
