whatismyipaddress.com Alternative
The generic incumbent vs an ad-free, API-first toolkit
whatismyipaddress.com is the long-standing generic incumbent: a solid "what is my IP" page, a set of lookup tools, a large educational library, and an extensive VPN review section. It is ad-supported — its homepage source includes Freestar ad-platform scripts.
The biggest practical difference is programmatic access. whatismyipaddress.com's own API page says it plainly: the IP-echo API was discontinued on November 10, 2021 "due to massive abuse", there is no API access to geolocation data, and scripted access to the site is not permitted. HackMyIP goes the opposite way: the entire toolkit is also a free, keyless, CORS-enabled REST API, and machine access is the point — including AI-readable surfaces like llms.txt and an OpenAPI spec.

whatismyipaddress.com facts from whatismyipaddress.com (homepage nav + page source) and whatismyipaddress.com/api (its own statements, quoted above), plus live 404 checks of /llms.txt and /.well-known/openapi.json — all fetched 2026-06-12. "Not in its tool list" means the feature does not appear in the site's own navigation. Dashes mean the feature is absent or unverified on that side.
When whatismyipaddress.com is the better choice
Honest answer: it has tools HackMyIP does not (phone number lookup, a personal data scan), a much larger educational article library, and a long-established brand. If you want human-readable explainers or VPN reviews, it is a reasonable place to read. HackMyIP is the right tool when you want a clean ad-free page, leak tests, and — above all — free programmatic access to the same data.
