Could you build this?
Partial Username and email checkers across sites are open-source-able, but a 1,000+ site product with verified profile data and source links needs large-scale crawling infrastructure and ongoing maintenance as sites change.
What it would actually take: Start from open-source username enumeration tools such as Sherlock or Maigret, then add a scraping and enrichment pipeline with a search index over profiles and an API layer. The hard parts are scale, keeping hundreds of site-specific parsers working, and sourcing reliable identity data. It also carries serious privacy and legal constraints that need compliance expertise.
