To know who unfollowed you on Instagram, you have to compare two follower lists taken at different moments: today's and an earlier one. Instagram doesn't notify you when someone leaves or keep a visible history of unfollows, so every method, manual or tool-based, comes down to that comparison.
How to know who unfollowed you on Instagram: the basic rule
You need an earlier list; without one there is nothing to compare against.
How to know who unfollowed you on Instagram without apps
There are two ways to do it without handing your password to anyone: manual comparison and Instagram's official export. Both work; the difference is how much effort they take depending on the size of your account.
Method 1: manual comparison
It works well for small accounts. The process, step by step:
- Open your profile and go to your followers list.
- Copy the usernames into a note or a spreadsheet, or take screenshots as you scroll.
- Save that file with the date in its name.
- A few weeks later, repeat the process and paste the second list next to the first.
- Sort both columns alphabetically and look for names from the first list that are missing from the second.
With a few dozen followers it takes minutes. With hundreds or thousands it gets slow and it's easy to skip names, so it's better to switch to the export.
Method 2: the official export
Instagram lets you download your information. It's free, doesn't require giving your password to any third-party app (Instagram itself may ask you to confirm it on its own page) and works as your earlier list. On the desktop version, the path guides report is:
- More, then Settings.
- Accounts Center.
- Your information and permissions.
- Export your information.
- Create export, and choose to include followers and following.
You can choose HTML or JSON format. Followers and following come in separate files, and you get the difference by cross-checking them in a spreadsheet. Instagram doesn't publish an official timeframe for the download; it can take a while, so request it ahead of time. The path changes with the app version; if you can't find it, check Instagram's Help Center.
Each export is a list from a single moment, so you need an earlier one to compare. A simple habit is to request one export a month and save it in a folder with the date. That way, when you want to know who left, you already have something to cross the current one against.
An example with a business account: a small shop saves its follower list before launching a discount campaign. Two weeks after it ends, it exports again and cross-checks both lists in a spreadsheet. If the names that disappear cluster right after the campaign posts, the shop already has a hint about the kind of message that didn't work with its audience.
How to know who doesn't follow you back on Instagram
It's a different and easier question: it needs no history, just a subtraction between two of today's lists. Cross your following list against your followers. The accounts you follow that don't appear among your followers don't follow you back. The official export includes both lists, so you can solve it in a spreadsheet without waiting for a second check.
In practice, paste the following list in one column and the followers list in another, and use a lookup to flag which names from the first don't appear in the second. Keep in mind that some accounts, such as brands or public figures, usually don't follow back, and that doesn't mean anything is wrong.
Third-party apps: the risk is the password
Many apps promise to show you who unfollowed you. Several ask for your Instagram username and password and process them on a third-party server. That is the central risk: you give access to your account to someone you don't know.
- Instagram may limit or end sessions it detects as automated. Review its terms of use.
- Some may show ads or charge subscriptions.
If you decide to use one, read who makes it, what it asks for and what it says about your data. And as a general rule, be wary of any tool that needs your password to do something that can be done without it.
If your followers dropped suddenly, maybe nobody left
Instagram may remove fake or spam accounts. When it does, your number can drop without any real person unfollowing you. If the drop was sudden and you didn't do anything different, it may be a cleanup and not a rejection. One way to check is to look at whether the missing names in your comparison are real profiles, with a photo and posts, or empty accounts.
When it matters who left and when it doesn't
On a personal account, it may be curiosity or a wish to tidy your contacts. On a business account, looking at names one by one rarely helps. What's useful is the trend: if you lose followers after certain posts, a change of tone or a campaign, it may indicate what content your audience isn't interested in.
A single unfollow doesn't say much. Several after the same type of content do. And if the account is part of how you get customers, it's worth more to take care of your content and consistency than to chase whoever left. To decide how much time to give this, see social media management for businesses: do it yourself or hire it out.

Unfollow Detective
Unfollow Detective is an Elevalia product that does the comparison for you. It runs in your browser, with no password or extensions. It compares against your earlier list, so the first time it only saves your starting point and differences show up from the second check. It doesn't send alerts, it isn't an analytics dashboard and it isn't affiliated with Instagram.
It costs $129 MXN as a one-time payment (about $7 USD), includes lifetime access to future updates, and delivery and support are through WhatsApp. Instagram's official export remains the free alternative, and if your account is small it may be enough for you.
One honest warning: any tool that automates something on your account may conflict with Instagram's terms of use, and this script does not guarantee that Instagram won't detect it. Review those terms before deciding. See who unfollowed you without giving your password.
