Instagram Follower Count Tracker - Bulk Profile Refresher

Update follower counts for a whole creator roster from usernames, and see what moved since last time. Paste handles, get current followers, following, posts, bio, category and contact email — plus the change since your last run, so a spreadsheet of creators becomes a monitoring feed. No login, no cookies, no API key.

⭐ bulk username lists · follower change between runs · one request per creator · new-post count · contact email where published · CSV/JSON/Excel · API, MCP & schedules

What does the Instagram Follower Count Tracker do?

Rosters go stale. Follower counts in a CRM, a media kit or a campaign sheet are wrong within weeks, and checking a few hundred handles by hand is a day's work. Point this at the list and every creator comes back current — with the delta against the previous run attached, so you can see growth, decline and new posts without keeping your own history.

What data does it return?

One row per creator:

Field	Description
username	Creator handle
followers	Current follower count
following	Accounts the creator follows
posts	Total posts
previous_followers	Follower count at your last run
followers_change	Gained or lost since the last run
followers_change_pct	That change as a percentage
posts_change	New posts since the last run
days_since_last_check	Age of the comparison
is_first_check	true the first time a creator is seen
full_name, biography, category	Profile basics and Instagram category
is_verified, is_private, is_business	Account flags
public_email, external_url	Contact email and link in bio, where published
profile_pic_url, url	Avatar and profile link
checked_at	When this row was captured
status	ok, or why a creator could not be read

How to update follower counts in bulk

1. Paste handles or profile URLs into Instagram creators, one per line.
2. Leave Track changes between runs on — the first run records a baseline, every later run reports the delta.
3. Run it, then download as CSV, Excel, JSON, JSONL or XML, or read it from the API.
4. Schedule it weekly or monthly and the roster keeps itself current.

Input example

{
  "usernames": ["mkbhd", "dave2d", "unboxtherapy"],
  "trackChanges": true,
  "onlyChanged": false,
  "concurrency": 8
}

Option	Type	Description
usernames	array	Required. Handles or profile URLs, one per line.
trackChanges	boolean	Compare against the previous run and add the delta fields. Default on.
onlyChanged	boolean	Return only creators whose follower count moved. Default off.
snapshotStore	string	Named store holding the previous counts. Default creator-snapshots.
concurrency	integer	Creators refreshed at once, 1–15. Default 8.

Pricing

Event	Price
profile-refreshed	$17.90 per 1,000 creators ($0.0179 per creator)

You are billed per creator row delivered. Private, deleted or unreadable handles return an error row and cost nothing. With Only return creators whose followers moved switched on, you are billed only for the creators that actually changed.

Use cases

Keep an agency roster current without manual checks

A few hundred creators refresh in under a minute. Schedule it weekly and every follower count in your sheet, CRM or media kit stays accurate on its own.

Track creator growth before and after a campaign

Run it the day before a campaign starts and the week after. followers_change and posts_change give you the growth the partnership produced, per creator, without a separate analytics tool.

Alert on sudden follower drops

Turn on Only return creators whose followers moved and schedule it daily. A large negative followers_change is an early sign of a purge of fake followers or a reputation problem on an account you are paying.

Re-score a database you already own

Follower counts decide tier and price. Refreshing the whole database quarterly keeps your rate cards and tier buckets honest.

Verify media-kit numbers during negotiation

Creators quote their best month. One run gives you the current count, the posting cadence and whether the account is verified or business — before you sign.

Good to know

• Each creator costs one upstream request, which is why this is the cheapest way to keep a large roster current.
• The comparison lives in a named key-value store, so it survives across runs, schedules and actor rebuilds. Use separate store names to track separate rosters independently.
• The first run on a new roster reports is_first_check: true and no deltas — it is establishing the baseline.
• Private accounts still return followers, following and post counts; their posts are what stays hidden.
• Follower counts come from Instagram as displayed, so very large accounts are rounded the same way Instagram rounds them.

Frequently asked questions

How do I update follower counts for a list of Instagram usernames?

Paste the list into Instagram creators and run it. One row comes back per handle with the current counts, and from the second run onwards each row also carries the change since last time.

Do I need an Instagram login, cookies or an API key?

No. Requests run through hosted infrastructure on our side — nothing to configure, and your own account is never used.

How does it know what changed?

Each run stores the follower and post counts per creator in a named key-value store, then compares the next run against it. Nothing is kept outside your own Apify account.

Can I track several rosters separately?

Yes. Give each roster its own Snapshot store name and their histories stay independent.

Does it work for private accounts?

Yes for the counts. Followers, following and post totals are public even on private accounts; only the posts themselves are hidden.

Can I get only the creators whose followers changed?

Turn on Only return creators whose followers moved. Unchanged creators are skipped and not billed, which makes daily monitoring cheap.

How fast is it for a large roster?

About one second per creator at the default concurrency, and it runs them in parallel — a 1,000-creator roster finishes in a couple of minutes.

What does it cost to refresh 1,000 creators?

$17.90, billed per creator delivered. Unreadable handles cost nothing.

Can I run it automatically every week?

Yes. Use Apify schedules, the API, the MCP server, or Make, Zapier and n8n.
