Typosquatting & Lookalike Domain Finder – Brand Protection

Expired & Dropped Domains — Daily Feed

nogards95/domain-drop-monitor-scraper

A daily machine-readable feed of expired and dropped domain names for threat-intelligence, brand-protection, and domain-investing workflows. Up to 10,000 fresh domains per feed per day, deduplicated, filterable by TLD, ready in seconds. No login, no API key.

Find registered lookalike domains impersonating your brand: typos, homoglyphs, hyphenations, phishing prefixes, and TLD swaps, checked live against DNS. Flags domains with a mail server (spoofing-capable) and shows registration dates. Keyless, no browser. Pay per lookalike found.

Typosquat & Lookalike Domain Detector with Threat Signals

cottony_brittlegill/domain-typosquat-detector

Find typosquatted and lookalike domains impersonating your brand: typo, homoglyph, bitsquat, TLD-swap and combosquat variants, checked against live registries and enriched with registrar, DNS, MX and TLS data to separate real threats from parked domains. Unregistered variants are never charged.

Domain Name Generator and Recommendations API

dev00/domain-recommendations-api

Generate domain name recommendations and semantic TLD variations from any search query using the Wix serverless engine.

Website domain name validator

saswave/website-domain-name-validator

Verify if a website is still up and running or if it contains a redirection to a new domain name. Data enrichment at scale.

Estimate domain value from verified sales using TLD, length, keyword, character, hyphen, digit, recency, and brandability signals with log-price outlier control.

Subdomain Finder — Certificate Transparency (crt.sh)

bgfc97/crtsh-subdomain-finder

Discover subdomains of any domain from public Certificate Transparency logs (crt.sh). Attack-surface mapping and recon with first/last-seen dates. No key, no proxy.

Resolve any DNS record types for thousands of domains via DNS-over-HTTPS, with NXDOMAIN detection. One row per domain.

Discover subdomains passively from public Certificate Transparency logs (crt.sh with CertSpotter fallback): unique hostnames, certificate count, first/last certificate date, issuers. No scanning or traffic to the target.

Validate EU VAT numbers in bulk against the European Commission's VIES service: valid/invalid, registered business name and address (where the member state provides it), request timestamp for audit trails.
