igtrackr

igtrackr is a free Instagram analytics and follower-tracking tool that works on any public account with no login, app install or card. Paste a handle to see followers, recent follows, unfollows, engagement and top posts, then track daily and weekly changes on a saved dashboard. It includes a Profile Analyzer, Instagram Follower Viewer (recent follows sorted by time), Engagement Rate Calculator with niche benchmarks, Hashtag Analyzer and CSV/JSON export. Note: igtrackr is a social-media analytics tool and is not primarily an AI product. Free to start; Pro ($9/mo) and Agency ($99/mo) add more tracked profiles, history, alerts and API access.
