Why Use This Tracker?

First run is a baseline of the current follower list (newest first)
Later runs emit only new_follower and unfollowed rows
Snapshot lives in a named key-value store in your account, so a schedule on the same Actor keeps working
Private and missing accounts return an error row and are not charged
Cap the walk (maxFollowers, default 2500) so a celebrity account cannot empty the wallet
changesOnly skips the baseline dump when you only want the next diff

How It Works

Resolve each handle and walk its public follower list up to maxFollowers.
Compare against the last snapshot in snapshotStoreName (default ig-follower-tracker).
Push change rows, then a free summary row (currentCount, newCount, unfollowedCount).
Write the new snapshot so the next run has something to diff.

Schedule the Actor daily or weekly on the same input. The named store is what makes it a tracker instead of another list scrape.

Input

Field	Default	What it does
`usernames`	required	Handles, `@handles`, or profile URLs
`maxFollowers`	`2500`	How deep to walk the current list
`changesOnly`	`false`	First run saves the snapshot without a row per follower
`snapshotStoreName`	`ig-follower-tracker`	Named store that holds the last list

{
  "usernames": ["nasa"],
  "maxFollowers": 500,
  "changesOnly": false
}

Output

Change row (rowType: "change")

Field	Meaning
`changeType`	`baseline` · `new_follower` · `unfollowed`
`username` / `userId` / `profileUrl`	The follower (or the account that left)
`previousSnapshotAt`	When the last snapshot was taken (`null` on baseline)
`sourceUsername`	The account you are watching

Summary row (rowType: "summary", not billed)

Field	Meaning
`changeType`	`snapshot_saved` · `diff` · `no_change`
`currentCount`	Followers stored this run
`newCount` / `unfollowedCount`	Diff against the previous snapshot

A scheduled run that found nobody new still returns a no_change summary, so the dataset is never empty after a successful walk.

Free Apify plan

On the free Apify plan a run tracks 1 account and up to 100 followers. The first 3 change rows of each run come back in full, so you can check the data. After that, change rows keep the change type, username, user id, full name, profile URL, verified and private flags and the dates, while the follower's profile picture is left empty and the watched account's follower count is rounded to its order of magnitude, and a freePlanNote field marks those rows. Summary rows are never masked. Any paid Apify plan returns every field in full.

FAQ

Do I need cookies? No.

Why is the first run large? It is the baseline. Turn on changesOnly if you only want later diffs.

Where is the snapshot stored? In a named key-value store in the account that ran the Actor. Keep snapshotStoreName the same on the schedule.

What about private accounts? They return private_account and are not charged.

What does it cost? $0.0001 to start the run, then $0.002 per baseline / new / unfollowed row. Summary rows are free.
