What the follow check tells you
Direction matters. A follow on X is one-directional, so this tool reports each direction separately and tells you when a follow is mutual.
Any public account. You can check any two public profiles, not only accounts you own or are logged into.
No account access. The check reads public follow data, so you never log in or authorize access to your account.
For manual methods and a full walkthrough, see our guide on how to check if one X account follows another.
Note: this tool checks the relationship between two accounts, not how many followers an account has. To see follower counts and other profile metrics, use compare two accounts.
What each result means
A follow on X is one-directional, so the checker reports both directions and labels the relationship.
Mutual follow. Both accounts follow each other.
One-way follow. One account follows the other, but the follow is not returned.
Not following. Neither account follows the other.
Cannot verify. One account is private (protected), so X hides its follow list.
How to check a follow manually
Open the profile you want to check, tap Followers, and search the second username in the list. On your own profile, a Follows you badge appears next to accounts that follow you. This is fine for one check but unreliable for large accounts, where X loads only part of the list. For every method in detail, see the guide on how to check if one X account follows another.
Check follows in bulk with the API
This tool checks one pair at a time. To verify follows across hundreds or thousands of accounts, for giveaways, ambassador programs, or audience audits, the check-follow API returns the same true or false for any pair in a single request, on a flat 20 requests per second across every plan, with no approval to get started.
curl -X POST https://api.sorsa.io/v3/check-follow \
-H "ApiKey: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"username_1": "TargetAccount", "username_2": "PossibleFollower"}'Returns {"follow": true, "user_protected": false}. follow is true when the second account follows the first.
Common uses
Giveaway and campaign verification. Confirm entrants follow the host account before picking winners. See giveaway verification.
Ambassador and partnership audits. Verify partners still follow the brand account.
Follow-back checks. See whether an account follows you back.
Mutual-connection checks. Confirm whether two accounts follow each other.
Frequently Asked Questions
Is this Twitter follow checker free?
Yes. The follow checker is free and needs no login, and you can check any two public accounts. For checking many accounts at once, use the check-follow API.
Do I need to log in or connect my account?
No. Management tools that bulk-follow or analyze your audience require you to authorize access to your account. This checker reads public follow data only, so you never connect or log in.
Can it check a private (protected) account?
No. X hides follow lists for protected accounts, so neither this tool nor any other can verify the follows of a private account.
Can I check many accounts at once?
This tool checks one pair at a time. For bulk verification, the check-follow API handles any number of pairs programmatically at a flat 20 requests per second.
Does running a check notify the other account?
No. The check reads public follow data and is completely passive, so neither account receives any notification.
How do I check if someone follows me back?
Enter your own account and the other handle. A mutual-follow result means they follow you back; a one-way follow means you follow them but they have not returned it. The check is read-only, so they are never notified.
What does it mean to be mutuals on X?
Two accounts are mutuals when each one follows the other. A mutual-follow result from this checker confirms exactly that: both directions return true.
Do I need an X developer account or API key to use this tool?
No. The tool runs in the browser with no login and no developer account. An API key is only needed if you switch to the check-follow API for bulk checks.
Can I check every account a profile follows, not just one pair?
This tool answers one pair at a time. To pull a full following or follower list, or to find every mutual between two accounts, use the followers and following endpoints and compare the lists, instead of a single follow check.
