I have no idea. I only use instagram to view tattoo artist portfolios and local techno party announcements. I just need to see the latest posts without signing up so I’m indifferent to it being open or close sourced for my needs.
I use iganony.io
It has a habit or showing a couple old posts before showing the most recent posts but it works well enough for me
Thanks, that really helps. Copying everything sounds like the quickest and simplest way but it’s good to know that everything is easily accessible.
