Seems related, so I’ll share here. I wrote an “awesome” list of privacy-focused front-ends[1] for a variety of services. Haven’t been updated in a while, but I figured it’s still valid.

Instagram doesn't actually work, right? All frontends are down, and it doesn't seem to work locally either.
That is correct, there's no alternative front-end that still works. Self-hostable open source ones, that is—you can still find random ones on search engines that aren't open source.
