There are directories of Fediverse projects:

• Fediverse.party
• Awesome ActivityPub
• Delightful Fediverse Apps

However, they tend to be a little messy and not easily skimmable. I also wanted to focus on Fediverse alternatives to existing services, although I do like the idea of going on beyond what is offered by current social media.

So, inspired by this discussion (and others), I thought a curated list of the main alternatives (with beginner-friendly sites) might be handy (especially with a potential influx of new users):

Reddit/threadiverse:

• Lemmy
• kbin

Twitter:

• Mastodon
• Misskey
• Pleroma
• Calckey

Social networks (Facebook, Google+):

• Friendica - works as a hub and publishing platform connected to the Fediverse and beyond (Twitter, Tumblr, etc)
• diaspora* - Friendica is technically part of diaspora*
• Socialhome

Instagram:

• PixelFed

YouTube:

• PeerTube

WhatsApp:

• Matrix - not as interconnected as the core ActivityPub services but it integrates well with Lemmy to provide secure DMs (just add your Matrix ID into your Lemmy profile)

Media hosting (Flickr, YouTube, SoundCloud, DeviantArt):

• MediaGoblin - are there public instances you can join?

Blogs:

• Write.as/Write Freely
• Plume

Activity planning (Facebook events):

• Mobilizon
• Bonfire

Goodreads:

• BookWyrm

Dropbox/Drive/Collaboration

• Nextcloud
• Owncloud - Nextcloud is a fork

LinkedIn:

• Polywork

Linktree:

• Linkstack

Music:

• Funkwhale

Podcasts:

• Castopod

Delicious:

• Postmarks

Dating apps:

• Alovoa - not yet part of the Fediverse but it’s planned

Pinterest:

• Pinetta - still early days there but as people have asked before

Search engine (although not federated themselves they search big chunks of the Fediverse):

• Lemmyverse
• Fedi-search - Lemmy, kbin, Mastodon and PeerTube
• Lemmy Search

And if you need some more background then try the Fediverse New User Orientation.
