Ditto is a tiny but powerful social media server for the decentralized web. With Ditto you will be able to interact across protocols and networks, and build your own social media experience.
Ditto is primarily a Nostr client, using a Nostr relay as its database. ActivityPub objects are translated into Nostr events in realtime and cached by the Ditto server. When you submit a post, it sends it to your Nostr relay and then fans it out to the ActivityPub network.
The main way to use Ditto is with a Mastodon app. Or you can connect directly to the Nostr relay with a Nostr client.
