mastodon
Mastodon is a decentralized social network platform. Using the ActivityPub protocol for federation, it enables free following and sharing of posts across independent servers (instances).
- Federation via ActivityPub protocol connecting independent instances
- Three timeline types: home, local, and federated for different content scopes
- Content warnings for considerate sharing with CW tags on posts
- Media support for images, video, audio, and polls attached to posts
- Moderation tools for instance administrators to set rules and manage content
- Account migration for moving to different instances while keeping followers
Built with Ruby on Rails, Mastodon has full Japanese UI support. As a Twitter/X alternative, Japan hosts some of the world's largest Mastodon communities with active instances like mstdn.jp and Pawoo.
