"Our new project, "Ditto", is a competitor to Mastodon.
It is an open-source, self-hosted social media server for online communities. While it borrows many ideas from Mastodon (including its API), it is built on the Nostr protocol. Ditto brings the best parts of Mastodon to Nostr, including dozens of native apps, and several new features not normally available on Nostr."
