I have made a list of alternatives for some popular online services. This is not exhaustive, of course (there are other sites that do that well). These are just the ones that I have found most common and useful.

Instagram Front-end: Bibliogram Replacement: Pixelfed

Reddit Front-end: Teddit Replacement: Lemmy

Twitter Front-end: Fritter or Nitter Replacement: Mastodon

YouTube Front-end: Piped or ViewTube (uses Invidious) Replacement: PeerTube

YouTube Music Front-end: Kainet Music Replacement: Bandcamp (maybe Funkwhale)

There are also a number of other open source tools worth mentioning.
