Mastodon screenshot

Mastodon is an open-source social networking server that implements the ActivityPub protocol to create a federated microblogging network. It provides chronological timelines, media-rich posts, moderation controls, and APIs for third-party integrations.

Key Features

  • Federation via ActivityPub: interoperable with other servers and fediverse software using open protocols.
  • Chronological, real-time timelines with streaming updates for follows and local/global timelines.
  • Rich media support: images, video, audio, polls, custom emojis, animated avatars, and accessibility captions.
  • Moderation and safety tools: local instance rules, content warnings, muting, blocking, reporting, and configurable filters.
  • Developer-friendly APIs: REST and streaming APIs with OAuth2 support for third-party apps and integrations.
  • Distributed account model: independent servers (instances) with local administration and moderation policies.
  • Scalable deployment options: containers, docker-compose and orchestration-friendly configurations with background job processing and caching.

Use Cases

  • Community networks: small to large communities that want moderated, self-governed social spaces without centralized corporate control.

  • Creators and publishers: sharing media-rich microblogs, threads, and announcements with audience control and content warnings.

Limitations and Considerations

  • Media storage and bandwidth can be resource-intensive; large instances need significant disk, CDN, or object-storage planning.
  • Federation introduces moderation complexity: instance-level policies do not automatically control content hosted on remote servers.
  • Operational overhead: running a production instance requires managing multiple components (web processes, streaming, background workers, DB, cache).

Mastodon provides a privacy-minded, standards-based alternative to centralized social platforms, emphasizing local governance and interoperability across the fediverse. It is suitable for projects that prioritize open protocols, community moderation, and control over data and timelines.
