Bulk Instagram Finder is a 100% free tool for a task that shouldn't be expensive. I built this after finding that most tools for finding Instagram accounts from a list of domains were part of huge platforms or services (like Apify) that charged $50+ for a simple list.
This tool is dead-simple. No sign-up, no credit card. You paste a list or upload a CSV, and you get a clean CSV back with the Instagram handles. It's for marketers, sales reps, and indie hackers who just need to get a job done.
