Like the question implies, I really want too get off of instagram. Its not the same space anymore, especially with the consistent push from Meta to use AI. Ive even made my profile private so those features don’t automatically turn on. Its gotten crazy there.
There are various technical alternatives (ActivityPub-based stuff like PixelFed/Loops/Mastodon/GotoSocial/Sharkey/Akkoma/something else on the Fediverse)
But would you take the plunge of self-discovering different content, which might as well be none of your topics of interests? Would you be acquainted of vastly different UI/UX such as the lack of recommendations, a million client frontends, and the technicality of federation? And lastly, will you find it a place with communities to socialize and content to enjoy from in the long run?
I think trying out on a public instance would be a good way to answer those questions. PixelFed most closely resembles Insta, but the other ones can do too. Then you can consider selfhosting your own
I haven’t gotten deep into self hosting yet, even though i do wanna try that with Jellyfin. For the insta alternative I prefer just posting and interacting with others.
