Free Instagram audience checker
Paste an Instagram handle and see what share of that account's audience looks genuine. No signup, no card. Measured from the official Instagram API against the engagement benchmark for that account's size.
What counts as a good Instagram engagement rate?
It depends entirely on account size, because engagement falls as an audience grows. Judging a million-follower account against a small account's benchmark is the most common mistake in creator vetting. These are the thresholds Ostryno measures against.
| Tier | Followers | Engagement benchmark |
|---|---|---|
| Nano | Under 10,000 | 6.0% |
| Micro | 10,000 to 50,000 | 4.5% |
| Macro | 50,000 to 100,000 | 3.0% |
| Mega | 100,000 to 500,000 | 2.0% |
| Elite | 500,000 to 1 million | 1.5% |
| Celebrity | Over 1 million | 1.0% |
An account running below a third of its tier benchmark is the pattern an inflated follower count leaves. That is a reason to look closer, not proof of anything.
How do I check if an Instagram account has fake followers?
Compare the account's engagement rate against the benchmark for its follower tier. A Nano account under 10,000 followers should see around 6% engagement, while an account over a million sits nearer 1%. Engagement below a third of its tier benchmark is the pattern inflated follower counts leave. Paste a handle above and this tool measures it.
What is a good Instagram engagement rate?
It depends entirely on size, because engagement falls as an audience grows. Ostryno uses 6% for accounts under 10,000 followers, 4.5% under 50,000, 3% under 100,000, 2% under 500,000, 1.5% under a million and 1% above that. Judging a large account against a small account's benchmark is the most common mistake.
Can you tell if someone bought Instagram followers?
You can see the pattern bought followers leave, which is not the same as proving a purchase. Followers who never engage depress the engagement rate, and likes without comments depress the comment-to-like ratio. Both are measurable. Neither establishes intent, and Ostryno does not accuse anyone of anything.
Why does Instagram checking need a Business or Creator account?
Because Instagram's official API only exposes data for Business and Creator profiles. Personal accounts return nothing at all, which is a platform rule rather than a limitation of this tool. Asking a creator to switch takes about thirty seconds in their settings and is free.
Is this Instagram audience checker free?
Yes. Checking an account's audience composition is free with no signup and no card. Signing up adds three full reports, each with every signal, its published threshold, and a written analysis of what the pattern suggests.
Does the creator know I checked their account?
No. Ostryno reads publicly available profile and post metrics through the official Instagram Graph API. Nothing is sent to the creator, nothing appears in their insights, and no follow, like or view is generated on their account.
What does audience composition mean?
Audience composition is the share of an account's followers whose behaviour looks genuine, against the share that looks suspicious. It is a measurement rather than a rating, which is why Ostryno leads with it instead of a score out of 100. A single number cannot carry a decision about whether to pay someone.
The composition is the start of the answer
A full report shows every signal with its published threshold, which checks triggered and why, and a plain-English read of what the combination suggests. Three are free on signup, no card required.
