Following up on a DNS lookup CLI tool I posted a while back, this one’s a small browser-based scanner instead of a CLI script.
What it does: you enter a brand keyword, it calls the WhoisFreaks Domain Typosquats API and lists every registered lookalike domain (typos, homoglyphs, compound squats). Then for any domain you want to check further, it calls the Domain Reputation API and returns a trust score plus a clear/monitor/block verdict.
Single HTML page, no backend to run yourself beyond a small serverless proxy (included) to get around browser CORS limits on the API. MIT licensed.

No backend, no build step. Just open index.html. · GitHub API docs: Domain Typosquats API Docs | WhoisFreaks
