SubDomainRadar is a service that is paused. It is no longer accepting scans, API requests, or new signups while the platform changes hands. Existing account data is retained, and recurring billing for active subscriptions has been stopped. The same team offers LeakRadar, a data breach monitoring service.
CrawlGraph is a backlink and competitor-gap tool built on Common Crawl snapshots. It returns referring domains with authority fields and compares competitors through a link-gap endpoint. It does not run a live daily crawler. The free website query returns five referring domains without signup; paid plans unlock full lists, CSV/JSON export, gap analysis and API access.
WebScore is a website legitimacy checker that produces a detailed report on a scanned URL. The report includes columns for URL Scanned, Uses HTTPS, Domain Age, Wayback History and Google Safe Browsing.
IP2Location provides a free IP lookup demo that reports geolocation and proxy data for an IP address. Results include country, region, city, coordinates, ISP, usage type, ASN, and proxy status. The demo uses the IP2Location DB26 geolocation database and IP2Proxy PX12 proxy database, and also shows an IP geolocation API response.
DNS History is a database of DNS record history that reports more than 2.2 billion nameserver changes detected and is updated daily. A premium bulk checker allows lookups of up to 5,000 domains at once, with export to Excel and CSV, and comparison of drops, changes and parked status across a list.
FullHunt is an internet intelligence infrastructure service that supplies internet asset, service, vulnerability and exploit data through REST APIs, data feeds and an MCP server. It also offers an enterprise platform for external exposure monitoring and a multi-tenant workspace for MSSPs. Pricing is listed for API, Enterprise and OEM access.
SeoTools for Excel is an Excel add-in for online marketing and SEO work, offering over 100 functions for tasks such as on-page and off-page analysis, plus connectors for services including Google Analytics and Majestic. It also includes a spider that crawls a list of URLs or a root URL.
