FediDB provides a list of instances available to join, along with their user counts, the software they’re running, and general environment growth.
Fediverse.Party also contains information about various federated software platforms.
- Friendica is a Facebook-like replacement. It integrates with most of the other popular ActivityPub-based solutions like Mastodon, but also works with diaspora*.
For non-federated options, check Link Aggregators
- Fedi.Tips has recommended this platform
This covers any sort of microblogging.
- Mastodon is one of the biggest options available.
The software is stable and there are many instances available to use already.
- The official site has lots of information about how it works and its key features
- They provide a list of servers that you can join that have committed to adhere to the Mastodon Server Covenant. This commitment provides some guarantee of stability, active moderation against hate speech, and promote decentralization.
- This was built by Cloudflare for deployment on their platform.
- Prepare to pay for this offering. As of 2023-06-12, their Requirements docs suggest that the minimum monthly cost is about $10/month USD for an instance, which isn’t too bad when shared with other people.
- Misskey seems to have a very anime/vtuber focus to its style. Its marketing content is written in Japanese.
- Pleroma is a lightweight, Mastodon-like option
written in Erlang/Elixer.
- Source code for Pleroma is hosted on their own GitLab instance.
- Akkoma supports a number of special features available on other systems, such as “Misskey Markdown” and boasts being 30-50% faster than Pleroma.
- GNU social is very much in the style of the original Twitter
The following are not compatible with Mastodon’s federation:
- I had used diaspora* in the past, but it’s a bit more of a walled garden. diaspora* pods can federate, but they can’t federate with Mastodon.
