Twitter Follow Checker
Sorsa Follow Checker shows whether one X account follows another, and whether they follow each other. Free, no X login.
Whether each account follows the other appears here, both ways, and whether they’re mutuals.
Each field takes a handle with or without the @, or a profile link.
How to check if someone follows someone on X
Open the profile of the account that might be following, tap Following and look for the other account. X shows only part of a long list, so a name you can’t find isn’t proof. Sorsa Follow Checker asks X directly: type both handles and see both directions in a few seconds, with no X login.
Here it takes one step: type both handles above and press Check follow. You get both directions at once.

Who follows who: what each result means
Every check asks X both ways at once, so the same check works as a following checker and a mutual checker. The answer is one of four.
Running a campaign that rewards follows? Here’s how to verify follows, reposts and replies through the API.
Mutual follow
Both accounts follow each other: on X they’re mutuals. If one of the two is you, the other follows you back.
One-way follow
One account follows the other, and the other doesn’t follow back. The answer says which way the follow goes.
Not following
Neither account follows the other. If one used to, it has unfollowed: X keeps no record of past follows.
Can’t check
One of the two accounts is protected and keeps its follows private, so no outside tool can tell.
Want to see everyone they follow?
This checker answers one question about two accounts. To see a whole list, everyone an account follows or everyone who follows it, open the Twitter Recent Followers Tracker: newest first, no X login.
Check a whole list of accounts
To find which accounts on a list follow you, call POST /check-follow on Sorsa API once per account, with your handle as username_1: 1,000 accounts cost from $1.40, at 20 a second, and your first 100 checks are free.
POST /check-followDoes one account follow another: true or false, one request each.GET /followersEvery follower of an account, 200 a page.GET /followsEvery account an account follows, 200 a page.
A shorter route for your own followers: GET /followers returns 200 a page, so 4,000 followers take 20 requests; match your list against them in a spreadsheet.
One call is one request, whatever it returns, and failed requests are never charged: Sorsa API pricing.
No credit card, and they never expire.

Questions about the follow checker
The follow checker
Is there a free tool to check if someone follows someone on Twitter?
Yes: this one. Sorsa Follow Checker checks any pair of public accounts for free, with no sign-up and no X account. To check a whole list against one account, a free Sorsa API key adds 100 requests, no card needed.
Does it check both directions?
Yes. One check asks X both ways, so it tells you whether the first account follows the second, whether the second follows the first, and whether the follow is mutual.
Will either account know I checked?
No. The checker only reads public data: you never sign in with X, and X sends no notification to either account.
What can I type in the fields?
A handle with or without the @, or a profile link from x.com or twitter.com. A post link works too: the checker takes its author.
Can it check a private (protected) account?
No. A protected account keeps its follows private, so no outside tool can check a pair that includes one.
Is it safe to use?
Yes. It never asks for your X login or password, needs no X developer account, installs nothing and shows no ads. Sorsa API reads public data through its own API and scraper, so your X account is never touched.
Can I check many accounts at once?
Not on this page, which checks one pair at a time. Sorsa API does: one POST /check-follow per account, 20 a second, from $1.40 per 1,000 checks, with your first 100 checks free.
Is this a DoesFollow alternative?
Yes. DoesFollow, the old yes-or-no checker, no longer works: doesfollow.com is parked for sale. This checker answers the same question, in both directions, with no X login.
Following on X
How do I check if two accounts follow each other (mutuals)?
Type both handles and press Check follow. “Mutual follow” means each account follows the other. On X itself you’d search two Following lists by hand.
What does a one-way follow mean?
One account follows the other, and the other doesn’t follow back. It’s common between fans and public figures, and after one side unfollows.
Can I see when someone followed an account?
No. X records no follow dates, so no tool can show the day of a follow made in the past. The checker shows the follow as it stands now; the Twitter Recent Followers Tracker shows who an account followed most recently, newest first.
How do I see everyone someone follows on X?
Open their profile and tap Following, or type their handle into the Twitter Recent Followers Tracker. For the whole list as a file, call GET /follows through Sorsa API.
Why can’t I find an account in someone’s Following list?
X shows only part of a long list, so scrolling can miss an account that’s there. The checker asks X directly, whatever the size of the list.
Does X tell you when someone unfollows you?
No. X tells you when someone follows you, not when they leave. To spot unfollows, check the account again here, or save your followers list through the API now and later and compare the two.
Does the official X API have a follow-check endpoint?
Not for any two accounts. Its connection_status field covers only relationships with the account you sign in as, through OAuth, at $0.010 per account read. Sorsa API’s POST /check-follow answers for any two public accounts with one API key.
Your own account
How do I check if someone follows me back on X?
Type your handle and theirs. A mutual follow means they follow you back; a one-way follow from you means they don’t. On X, a profile that follows you shows “Follows you” next to its handle.
How do I see who unfollowed me on X?
X keeps no list of unfollows. Check a suspected account here: if it no longer follows you, it unfollowed. To list everyone you follow who doesn’t follow you back, use the Twitter Not Following Back Checker.
How do follow requests work on X?
Follow requests exist only on protected accounts: X asks the owner to approve or deny each new follower, and the follow starts once it’s approved. Pending requests stay private, so no outside tool can see them.
How do I see who I follow on X?
Open your profile and tap Following. Or type your handle into the Twitter Recent Followers Tracker and switch to Following: newest first.
Verify a giveaway’s follows in one run
Which entrants follow the host? Sorsa API checks every one: one request per entrant, 20 a second, from $1.40 per 1,000 checks.
No credit card, and they never expire. 6B+ requests served since 2022.

1. Open the profile that might be following
In the X app or on x.com, open the account you think follows the other one.
2. Tap Following
The count under the bio opens the accounts it follows, the newest at the top.
3. Look for the other account
Scroll for its name. For your own account it’s quicker: a profile that follows you shows “Follows you” next to its handle.
