Mastodon
The social network that gives you back control
Follow your friends and discover new ones. Post what you want: links, images, texts, videos. All this on a free platform and respectful of your data.
You're a person, not a product.
Mastodon is not a commercial network. Here, no ads, no data prospecting and no closed environments. There is no central authority and this body hosted by Zaclys is just one of thousands of others.
A more humane approach
Having learned from the failures of other networks, Mastodon has the ambition to combat the abuse of social media by making ethical design choices.
Mastodon is a social network using open formats and free software. Available in web and mobile applications.
Sharing your thoughts has never been more convenient
You have 500 characters. You can adjust the framing of the miniatures of your photos. You can use handmade emoji, hide things behind spoiler warnings and choose who can see any status. A mistake? You can quickly delete and edit your messages.
A safer social media experience
Mastodon contains effective anti-abuse tools to help protect you. Thanks to the extensive and independent nature of the network, there are more moderators you can turn to for personal help, and servers with strict codes of conduct.
Mastodon for individuals
Since there is no incentive to sell you anything, Mastodon allows you to enjoy content without interruption. Your News Feed is chronological, without ads or algorithms, you decide what you see!
Find your ideal community
Mastodon is not just a service, it is a federation… kind of like Star Trek. Thousands of independent communities using Mastodon form a coherent network; if all the planets are different, when you live on one, you live in the whole.
Chaque serveur est indépendant
Mastodon is free and free software that anyone can install on a server. Independent operation, independent rules.
Le réseau est interopérable
HelpSSs Because they use a set of standard protocols, Mastodon servers can exchange information with each other, allowing users to interact seamlessly.
Mastodon est à l’épreuve de l’avenir
Thanks to standard protocols, the network is not limited to Mastodon servers. If better software arrives, they can continue with the same social chart.
Mastodon est robuste
The network is resistant to financial, technical and organizational problems, as well as government interference, because of its diverse nature.
Free network so I'm the product?
The service is free and accessible to all. Zaclys is a French association that offers alternative services for privacy. We just ask to make reasonable use of it and the members have advantages (detailed here) to encourage to contribute (5 or 10 euros per year). This is what has allowed all of this to exist since 2008.
Mastodon is an open source software that Zaclys uses to offer you this service. You can directly support the authors of this software here:
