© 2026 UnfollowersTrack
Track another Instagram account's follower changes
Yes — you can view the follower changes of an Instagram account that isn't yours, as long as that account is public. Here's how scan-based tracking works for social managers, brands, and creators, which tools can actually do it, and what no tool can show you.

Full disclosure: UnfollowersTrack is our product, so it tops our own list. The short list isn't padding — most trackers structurally can't check an account that isn't yours, as explained below.
Who actually needs this
Checking a public account you don't own sounds niche until you've had to do it for work. Three groups run into it constantly:
Social managers running client accounts
Audit a client's follower changes without anyone handing a password back and forth between agency and client — the scan works from the public @username alone.
Brands benchmarking a competitor
Watch a competitor account's follower churn between your scans and put your own growth numbers in context.
Creators vetting a collab
Before committing to a collaboration, look at a partner account's recent public follow activity and how its follower base is trending.
What you can and can't see
This page stays useful only if it's straight with you about the limits, so here they are.
You CAN see
Public follower and following lists, and how they change between your scans. A scan shows a profile's recent public follow activity; unfollows are detected by comparing later scans against your first, and history builds from that first scan onward.
You CANNOT see private accounts
A private account's follower list isn't publicly visible, so no tool — ours included — can track it. Full stop.
You CANNOT see likes, DMs, or activity logs
We compare public follow lists between scans; we don't log what an account likes or comments on. Activity monitoring is a different product category (Snoopreport's, specifically).
You CANNOT get real-time alerts
Results update when you run a scan — no tool reading public data can honestly promise alerts in real time. Anything claiming otherwise deserves skepticism.

Why login apps and ZIP-export tools can't do this
The short table above isn't cherry-picked — it's structural. Almost every unfollower tracker belongs to one of two families, and both are locked to a single account by design.
Login apps see the logged-in account
FollowMeter, Reports+, InsTrack, and Followers & Unfollowers all work by signing in with an Instagram account — so they report on that account and nothing else.
Example: UnfollowersTrack vs FollowMeterExport tools see the account behind the ZIP
FANS, Unfollr, and DontFollowBack analyze Instagram's official data export — which Instagram only issues for your own account. Password-free, yes; other accounts, no.
Example: UnfollowersTrack vs FANSScan-based tools read public data
UnfollowersTrack, Dolphin Radar, and Snoopreport work from what a public profile already shows to anyone. That's the only architecture that can check an account that isn't yours — and it's also why private accounts are off-limits for all three.
Example: UnfollowersTrack vs SnoopreportWorks for business, creator, and personal accounts
There's no Professional-account gate here: UnfollowersTrack doesn't require a Facebook login or a business profile (that's InsTrack's requirement, not ours). Personal, creator, and business accounts all work the same way — if the profile is public, you can scan it. That includes client accounts you manage, with no password sharing involved.
One honest sizing note: scans currently support accounts up to around 10,000 followers, which covers most personal, creator, and small-brand profiles.
How to run a scan on any public @username
Enter the @username
Type the public profile's handle — a client account, a competitor, or a collab partner. If the account is private, the scan can't read it (no tool can).
Review the first scan
The first scan captures that profile's followers and its recent public follow activity. This baseline is where the account's history starts — so scan early if you'll want trends later.
Re-scan to see changes
Unfollows are detected by comparing later scans against your first. Each new scan adds to the picture: who followed, who unfollowed, and how the account is trending between your visits.
