UnfollowChecker vs FollowSpy

How each one works

FollowSpy doesn't ask for your password. You type a username into its dashboard and its servers pull that profile's public follower and following lists, then show recent changes and a timeline. Starter tracks two accounts, Pro tracks unlimited accounts. Results arrive in seconds. It is web-first, with an iOS app from the same company, and it only works on public accounts. Note that a separate, unrelated "FollowSpy: Follow Tracker" app on the App Store ($5.99 a week, $24.99 a year) shares the name; this page is about followspy.ai.

UnfollowChecker never connects to your account. You ask Instagram for your own data (Accounts Centre → Export your information → Followers and following, JSON, All time), Instagram emails you a ZIP in roughly 10–20 minutes, and you drop that ZIP on this site. The comparison runs in your browser tab; the file is never uploaded. The count is free, the followers and following CSVs are free, and the two-export unfollowers comparison is free. The full list of who doesn't follow you back is a one-time $2.99, with fans and mutuals a $3 add-on.

Safety and account risk

Neither tool logs into your Instagram account, so neither can get it restricted. FollowSpy's exposure is on its own side: it collects public data with automated requests, which Instagram's terms don't permit, so the service lives or dies on Instagram's tolerance. The bigger safety question with FollowSpy is financial. Its Trustpilot profile carried a notice that the company had breached review guidelines at the time of checking, with reviews mentioning no refunds once a subscription is active and unexpected charges. One App Store review describes spending about $200 before discovering the public-only requirement, and being refused a refund.

UnfollowChecker has no account on its side either. There is no subscription to cancel and nothing is collected from anyone; it reads a file Instagram gave you, in your browser. Our checks are on how we test. Both tools pass the password check; only UnfollowChecker passes the private-API check.

What you get

FollowSpy shows, for any public account, recent follows, recent new followers, and unfollowers, with growth trends and a story viewer that doesn't notify the account. It is designed for watching other people, and it does that well. It does not produce a full "everyone who doesn't follow me back" reconciliation of your own account, has no CSV export that we could find, and shows nothing for private profiles.

UnfollowChecker gives you the complete non-followers list, fans, mutuals, free CSV downloads of both raw lists, and a free two-export unfollowers comparison, for your own account, private or public. It also reads Threads and TikTok exports. It cannot watch anyone else's account, cannot view stories, and has no alerts.

Price

FollowSpy Starter is $12 a week or $109.99 a quarter; Pro is $14 a week or $127.99 a quarter. Those are shown as 60% off list prices of $30–$35 a week. At $14 a week, a year is over $700. There is no usable free tier — a username search shows a teaser before the paywall. Reviews say refunds are not given after activation, so the first charge is the commitment.

UnfollowChecker: free count, free CSVs, free unfollowers comparison, $2.99 once for the full non-followers list, $3 for fans and mutuals. One week of FollowSpy Starter would pay for the full UnfollowChecker list four times over.

When FollowSpy is the better choice

Choose FollowSpy when the account you want to watch isn't yours and is public — a brand, a competitor, an ex, a public figure — and you want to know who they follow and who leaves them. UnfollowChecker cannot do this at all. Choose it too if you want results in seconds with no export step, and the weekly price is acceptable for a short, specific purpose. If you do, cancel on day one so the renewal doesn't catch you.

When UnfollowChecker is the better choice

Choose UnfollowChecker when the account is your own — especially if it's private — and what you want is the full list of who doesn't follow you back, who unfollowed you, and your raw lists as CSV. It is one payment, no renewal, no refund policy to worry about, and it works without a password on any device with a browser. For the broader case, see checking without a password.
