Find your perfect community

Mastodon isn’t just a website, it is a federation—think Star Trek. Thousands of independent communities running Mastodon form a coherent network, where while every planet is different, being part of one is being part of the whole.

Safer social media experience

Mastodon comes with effective anti-abuse tools to help protect yourself. Thanks to the network's spread out and independent nature there are more moderators who you can approach for personal help, and servers with strict codes of conduct.

Sharing your thoughts has never been more convenient

You have 500 characters. You can adjust the thumbnails of your pictures with focal points. You can use custom emojis, hide things behind spoiler warnings and choose who sees a given post. Messed it up? You can delete & redraft for quick corrections.

Mastodon for the individual

Sign up

All you need to do to sign up is choose a server. Just like when signing up for an e-mail address, one server is going to be hosting your account and be part of your identity. Remember, you can follow and talk to anyone from any server, regardless of your choice!

No results… for now!

Install your own

If you are interested in running your own server — for your friends, family or organization — you can get started by reading the installation documentation. You only host your own users and the content that they subscribe to, which means it's quite scalable and resource-efficient.

Each server is independent

Mastodon is free, open-source software that anyone can install on a server. Independent operation, independent rules.

The network is interoperable

Using a suite of standard protocols, Mastodon servers can exchange information with each other, allowing users to interact seamlessly.

Mastodon is future-proof

Thanks to standard protocols, the network is not limited to Mastodon servers. If better software comes along, it can continue with the same social graph.

Mastodon is robust

The network is resistant to financial, technical and organizational issues, as well as government interference, due to its diversified nature.


Mastodon is free, open-source software. There is no advertising, monetizing, or venture capital. Your donations directly support full-time development of the project.
