As answered by people managing JavaScript Tutorial and Lookalike-Domain Finder.
Lookalike-Domain Finder's answer:
Most lookalike-domain tools are built for security teams. They hand you a spreadsheet of DNS records and expect you to already know what to do with it. This one is built for the business owner instead: enter your domain, and it tells you in plain terms which fake versions are registered, which have a live website, and which ones can actually send email pretending to be you. That last one is what matters for invoice fraud. No signup, no account, nothing to install.
Lookalike-Domain Finder's answer:
It's free and it answers the question a small business owner actually has, not the analyst version of it. Tools like domainIQ or Whiteintel are built for enterprise brand-protection teams and sit behind a subscription. Free tools like dnstwist or openSquat will generate the list of lookalike domains, but they stop there. This one checks which of those domains have mail servers configured, because a registered typosquat that can't send email isn't the one you need to worry about.
Lookalike-Domain Finder's answer:
Small business owners and office managers, not security professionals. Most people who use this have never heard the word "typosquatting" and don't have an IT team to ask. They're usually checking because an invoice looked slightly off, or because a client mentioned getting a strange email that looked like it came from them.
Lookalike-Domain Finder's answer:
I run SecureBusinessHub, a publication that writes plain-English cybersecurity guides for small businesses. While researching invoice fraud and business email compromise, I kept running into the same gap: every lookalike-domain checker out there is built for security analysts and outputs a table of DNS records with no explanation attached. Small business owners don't have that context, and they shouldn't need it. I built this to answer the actual question: is someone impersonating me right now, and can they send email as me.
Lookalike-Domain Finder's answer:
It runs on Cloudflare Workers, with the frontend built in React and TypeScript. Domain lookups go through DNS-over-HTTPS to Cloudflare's own resolver rather than a third-party API, so there's no external service in the loop and nothing to manage. Usage gets logged to a Cloudflare D1 database, just the tool name and result tier, never the domain someone actually checked.
