Servers Mastodon is not a single website. To use it, you need to make an account with a provider—we call them servers —that lets you connect with other people across Mastodon. Mastodon is a free and open-source software that lets you join or create your own server and communicate with anyone across the fediverse. It respects your privacy, control and creativity, and has no ads or algorithms. Open API Mastodon is open-source and has an elegant, well-documented API that is available to everyone. Make your own app, or use one of the many third-party apps made by other developers! Mastodon, Inc. Mastodon, Inc.
