AppRanks verdict
Generated from live marketplace data — refreshed daily
OWH Domain WHOIS RDAP is a category-leading WordPress app with a limited review volume. It is listed in the Search category on WordPress Plugin Directory, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 1 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.

External Services This plugin connects to external services to obtain domain information and TLD validation data. These services are essential for providing accurate domain availability information and ensuring proper domain validation.
IANA RDAP DNS Bootstrap Service
What the service is: IANA RDAP DNS Bootstrap Service (https://data.iana.org/rdap/dns.json) – The official Internet Assigned Numbers Authority service for RDAP server discovery
What it is used for: Primary source for obtaining the official list of TLD (Top Level Domains) and their corresponding RDAP servers

When data is sent: During TLD list updates (manual or automatic) and when validating domain extensions
RDAP Servers (Various Domain Registries)
What the service is: Various RDAP servers operated by domain registries and registrars worldwide (e.g., Verisign for .com/.net, PIR for .org, etc.)

– All communications use secure HTTPS connections
– The plugin respects rate limiting and best practices for RDAP queries
