Mastodon account stats
Look up any public Mastodon account on any instance for live follower counts, posting cadence and an engagement rate built from real favourites, boosts and replies.
Calculated from up to 30 recent original posts — reposts are excluded, because someone else’s engagement is not yours. Figures move as new posts land.
How do you check Mastodon engagement?
Enter a full fediverse address — @user@instance.social — and the tool queries that instance's public API for the account and its recent original posts, then averages favourites, boosts and replies against the follower count.
No login and no API key, because Mastodon instances answer public requests by default. The instance name is required: the network is federated, so there is no central place to look a username up.
Mastodon engagement rate
(Favourites + Boosts + Replies) ÷ Posts ÷ Followers × 100
Why Mastodon numbers are a floor, not a total
Mastodon has no central database. Each instance keeps its own copy of what it has seen, built from the servers it federates with. When someone on a distant instance favourites your post, that interaction only appears in your instance's count if the two servers are talking.
In practice, well-connected instances see most interactions and small or newly defederated ones see fewer. The effect is real but usually modest — and it always runs in the same direction, which means your true engagement is at least what is shown here and possibly a little more.
It also means two tools can legitimately report different numbers for the same account if they query different instances. Neither is wrong; they simply have different views of the network.
Reading Mastodon engagement fairly
Mastodon has no ranking algorithm. Timelines are chronological, and a post is seen by the people following you who happen to be looking, plus whoever sees a boost. There is no recommendation system to rescue a good post from bad timing.
That makes boosts the entire distribution mechanism. An account with a modest favourite count but a high boost rate is reaching far beyond its own followers; one with the reverse is popular with the audience it already has. The boost-to-favourite ratio is genuinely the most informative number on this page.
It also means posting time matters more here than on algorithmic platforms, where the feed will resurface a post hours later. On Mastodon, a post published while your audience is asleep is largely a post nobody sees.
The other open network
Bluesky is the only other major platform with genuinely free public data access — the Bluesky engagement checker works the same way. For every closed platform, the engagement rate calculator applies the right formula to numbers from your own analytics.
Common questions
How do I check Mastodon stats without logging in?
Every Mastodon instance exposes a public REST API that returns account and post data without authentication. Enter a full address like @user@mastodon.social and this tool queries that instance directly for the follower count and the interaction counts on recent posts, then calculates an engagement rate from them.
Why do I need the full @user@instance address?
Because Mastodon is federated — there is no central directory. The same username can exist on hundreds of instances, so the instance name is the only way to know which server to ask. A profile URL like https://mastodon.social/@Mastodon works too.
How is Mastodon engagement rate calculated?
Favourites plus boosts plus replies across recent original posts, averaged per post, divided by the follower count, times 100. Boosts of other accounts' posts are excluded. Around 2% is typical, above 4.5% is strong.
Why might the numbers be lower than expected?
Federation. An instance only knows about interactions that have reached it, so favourites and boosts from distant servers it does not federate with may not be counted. Mastodon numbers should be read as a floor rather than an exact total — the real engagement is usually somewhat higher.
Can I check accounts on any instance?
Any public instance that has the standard Mastodon API enabled, which is the overwhelming majority. Some instances restrict public API access or require authentication; those will return an error rather than data.
Does this work for Pleroma, Akkoma or other fediverse servers?
Often yes. Many fediverse projects implement the Mastodon API for compatibility, so they respond to the same requests. Support is not guaranteed and depends on how closely a given server follows the specification.
