PeerTube is a free, open‑source video platform that operates across a federated network of independently run instances. Users can join an existing instance or create their own, upload videos, and stream them without vendor lock‑in. The platform uses ActivityPub to interoperate with other Fediverse services such as Mastodon, allowing creators to follow channels without needing accounts on each instance. Content can be embedded on external websites, and livestreaming is supported through compatible clients. Instances share bandwidth by caching videos for one another, enabling smaller hosts to reach broader audiences. Creators can receive direct support via donation links, and the project invites contributions through bug reports, translations, and documentation. Technical details include a REST API described by an OpenAPI 3.0 schema, ActivityPub documentation, and a GNU Affero General Public License.
