About

Mastodon is a free, decentralized social network, and every server ships the same well-documented API. Register an app (or just get a token), and you can publish and schedule posts, upload media, read timelines and notifications, search, follow accounts, and manage lists. There is no developer portal or approval queue; your account on any server is all you need. It is ideal for indie cross-posters and fediverse analytics experiments.

Details

Free to start. You may need a free key, but no credit card.
