instagramの相互フォローチェッカー

DolphinRadar (dolphinradar.com) lets you check mutual follow status between any two public Instagram accounts in seconds. Enter a username on the Mutual Follow Checker page, and the tool instantly shows which connections are two-way follows. No Instagram login is needed, and the account owner receives no notification. The free tier shows partial results, while the full plan starts at $4.50 per week on the quarterly plan.

On Instagram, a mutual means two accounts follow each other. DolphinRadar helps you identify these mutual connections for any public profile without logging into Instagram. The mutual follow checker displays all two-way connections in one view, covering 3 relationship types: one-sided follows, new mutuals, and long-standing mutual connections.

No. DolphinRadar can only check mutual followers on public Instagram accounts. This is an Instagram platform restriction, not a tool limitation. Private accounts hide their follower and following lists from all external access. If a private account later switches to public, DolphinRadar typically shows results within 10 minutes of the change.

No. DolphinRadar’s mutual follow checker is 100% anonymous. No Instagram login is required, no notifications are sent to the account owner, and no traces are left behind. Your search activity is completely private. The tool analyzes publicly available Instagram data without interacting with any account directly.

A recent follow tracker shows who someone followed in chronological order. DolphinRadar’s mutual follow checker goes one step further by cross-checking both directions, revealing which follows became mutual. DolphinRadar offers both tools separately: the Recent Follow Tracker covers one-way follows, while this page focuses on two-way mutual connections.

DolphinRadar’s mutual follow checker starts at $4.50 per week on the quarterly plan ($58.50 billed once per quarter). The weekly plan is $6.00 per week with no long-term commitment. Free searches show partial results. Paid plans include unlimited mutual follow checks, chronological activity timelines, and email alerts when new mutual connections form for 1 tracked account.

Yes. DolphinRadar only accesses publicly available Instagram data and does not require any account credentials. All mutual follow checks are conducted within Instagram’s terms of service for public profiles. Payment processing is handled by Stripe, and DolphinRadar does not store any payment information on its servers.

Instagram does not offer a built-in feature to check mutual followers between two accounts you don’t own. You can only see a “Followed by [name]” label when you share a mutual connection. DolphinRadar solves this limitation by letting you check any public account’s full mutual follow list without needing to follow them first. Results typically load in under 5 seconds.
