Compare Followers Across Social Networks
A common-followers comparison lists the people who follow two or more accounts at once. It's the fastest way to tell whether a partner, competitor, or influencer reaches your audience or a new one. Fedica's Compare Followers runs that comparison on X (Twitter), Bluesky, and Mastodon.
Networks
Pick a Network
X (Twitter)
The original Compare Followers. Find who follows two competitors, then send that group straight to an X Ads Audience.
Bluesky
Works with bsky.social and custom-domain handles. Check a starter pack's reach, or rebuild your network after moving from X.
Mastodon
Compare accounts on different servers. Accounts that hide their follower list are respected and add nothing to the count.
Use Cases
What Follower Overlap Tells You
Overlap answers one question with money attached: are you about to pay to reach people you already have?
- Influencer vetting: compare two creators you're considering. If their audiences overlap heavily, one of them may be enough.
- Competitor analysis, because the people who follow two competitors are the audience your whole category is fighting over.
- Collaboration planning. Low overlap between you and a partner means a joint event or campaign puts each of you in front of new people.
How Compare Followers Differs by Network
| Spec | X (Twitter) | Bluesky | Mastodon |
|---|---|---|---|
| Handle format | @name | name.bsky.social, a custom domain, or another AT Protocol service like Blacksky or Eurosky | @user@instance.social, any server |
| Accounts per comparison | Two to 30 | Two to 30 | Two to 30 |
| Export and save lists | Supported | Supported | Supported |
| Network-specific | Send to an X Ads Audience | Custom-domain handles | Hidden follower lists respected |
Every comparison shows the overlap for each pair of accounts, plus the followers all of them share. See Fedica's plans for pricing.
FAQ
Frequently Asked Questions
What's the difference between common followers and mutual followers?
- People search for both, and they usually mean the same thing: accounts that follow two or more profiles at once. Strictly speaking, a mutual is someone who follows you and whom you follow back. Common followers are the people two accounts share, and neither account has to be yours. Fedica's Compare Followers finds common followers, which covers the mutual-followers question too when one of the accounts is yours.
Can I compare accounts that aren't mine?
- Yes. Comparing two competitors, or a partner and yourself, is the point of the tool.
How many accounts can I compare at once?
- Up to 30, on every network Fedica's Compare Followers supports.
Which Fedica plans include Compare Followers?
- Compare Followers comes with Fedica's Research plan (or higher) on X (Twitter), Bluesky, and Mastodon.
