The number of users on your Mastodon server is just one of the factors that influence resources needed.

Every time you or a user on your server follows or is followed by a remote user, that will have an impact - this depends on multiple factors, from the popularity of that remote user to the general usage.

So if you want to keep your usage low, it's best that you and your users don't engage in mass following of users and avoiding the usage of federation relays as much as possible.

All plans will use the latest stable release of Mastodon.

Custom Mastodon forks, other Activity Pub software and code changes are not supported.

Mastodon does provide a Custom CSS option in the administration interface and you can use it for basic customization of the web interface.

You should read the Terms of Service where you will find more details about the service.

Also, you should note that communities focused on illegal activities or becoming a gathering for users promoting the following topics, will be banned:

• Sexual content involving minors, including artistic depictions
• Gore and extremely graphic violence, including artistic depictions
• National Socialism
• Nazism
• Holocaust denial
• Racism
• Alt right, including under the disguise of freedom of speech
• Gender-critical
• Sex and gender discrimination
• Transphobia
• Misogyny
• Pro-ana / Pro-mia

By subscribing to one of the plans you are agreeing to the Terms of Service.

The database disk space limit is not a hard limit, meaning, that if you go over the limit for a couple of days your server will not be suspended or somehow throttled.

If you go over the limit you will be contacted and asked to purchase extra disk space before any suspension is applied.

You can check your database usage in your Mastodon server by going to Preferences->Administration->Dashboard under Space Usage, PostgreSQL.

The number of registered users on your server is not limited. There is also no limit on the number of active users. This value is just provided to give a rough estimate based on usage seen across Mastodon servers.

You can check the number of active users in your Mastodon server by going to Preferences->Administration->Dashboard under 'Active this week'.

To provide a rough idea on how Mastodon federates, you can think of it as:

• Every time you favourite, boost or reply to a post that information needs to be federated so the account that made the original post knows of your interaction;
• Every time you post, that post needs to federate, so that the users following you can see it on their timelines/server;
• Every time someone that you follow posts or makes an interaction with your posts that also needs to federate in order for you to see that post/interaction.

Be aware that it's more complex than this and you also need to factor that if you have multiple users in your server, this applies to every user.

In general, the more users you and other users in your server follow, the more popular you and your posts become and the more Federation Capacity you will need.

The Federation Capacity levels (low, moderate, medium, high, very high) are provided to help you have a sense of how much the Concurrent Requests limit the Federation.

The concurrent requests limit is the sum of the concurrent federation jobs plus the short-lived HTTP requests made to your Mastodon server.

Example: if your plan has a limit of 4 concurrent requests, your server can only perform 2 concurrent federation jobs and 2 concurrent short-lived HTTP requests simultaneously.

When all the concurrent requests are occupied, new requests will be queued.

Using the previous example, where a limit of 2 concurrent short-lived HTTP requests is in place, if 3 people attempt to access the web platform at the exact same time, 2 will immediately be processed and the third will need to wait (in this case, it should take milliseconds).

As explained in the Terms of Service, the unlimited media storage anticipates that you and your users use Mastodon has social media platform and not as storage for media files.

Also, it is only to possible to offer unlimited storage thanks to the automated cache deletion and if you want the cache deletion not to be executed on your server, you should request it to the email info@masto.host and you will be billed per GB of disk space usage and download transfers.

Finally, the unlimited media storage covers no more than 2 GB of monthly download transfers per GB of storage.

In order to keep your Mastodon server storage space usage (both database and media) as low as possible, there is a regular automated remote cache deletion.

Currently that is applied to remote media attachments, preview cards and posts from unfollowed users. This may change in the future, as Mastodon introduces more hosting sustainability tools and new features.
