Mastodon is a vibrant social network home to 2 million users

With hundreds of communities that cater to the most varied set of subjects, Mastodon is a true internet community: No central hosts, no corporate-owned environments, and no ads.

Federated Network

There are no central authorities in Mastodon. The entire network is based on individual and community-owned servers — or instances — that communicate with each other in a transparent manner.

Learn More About Mastodon


Mastonaut is an easy-to-use and beautiful window into this world. Browse, follow, interact, and contribute to this amazing community from the comfort of your Mac.

As a lovingly-crafted app from a Mastodon user to other Mastodon users, Mastonaut is made to integrate with macOS in the finest aspects. Some features include:

  • Thoughtful interface, made for the Mac, with simple usability and powerful capabilities.
  • A concise status composer, that also lets you submit posts with image and video attachments that can be drag-and-dropped from Finder.
  • Keyboard navigation, so you can quickly browse through your feed
  • Polls support: Vote on polls right from your timelines, and compose your own, right from Mastonaut.
  • Instance emoji support: Each mastodon instance has its own set of custom and often animated emoji. Mastonaut makes sure you can enjoy them at their best by letting you see them in your timelines, and also letting you insert them using a picker in the composer. But if you're a pro you can also insert instance emoji by simply typing their shortcode between colons.
  • Versatile column-based layout, that allows browsing anywhere from a simple and straightforward single-column mode, to a many column window that lets you keep everything that's happening now right in front of you.
  • Multi-Account support, so that you can manage and post from several accounts (even in different servers) at once (and quickly switch between them via keyboard shortcuts).
  • Mention auto-complete: Just type the first few characters from a user's handle to get Mastonaut to suggest them to you.
  • Full support for media and content warnings (spoiler warnings), so that you don't have to see what you don't want to see.
  • Annotated media support, so you can access the accessibility labels of attachments in posts, but also insert annotations on your own posts.
  • Search: Find users by handle or display name, and lookup hashtags.
  • Delete & Redraft: We all make typos, so Mastonaut lets you quickly delete and re-draft your statuses. It will even reuse the attachments from the original status so you don't need to upload them again.
  • Notifications: Get notified when other users mention you, or favorite your toots. Notifications can be configured per account.
  • Share extension: Share webpages, text, and images right from other apps such as Safari, Photos, or Finder.
  • Saved tags: Bookmark your tags to easily browse through them later.
  • Account editing support: You can update most of your accounts settings from Mastonaut, including your avatar and header, your bio, fields, and more.
