ipapi.is versus Ipengine (IPWho)
Compare	ipapi.is	Ipengine (IPWho)
Verdict	Worth it	Depends
Best for	Developers embedding IP geo in apps	Hobby and homelab projects
Who it's not for	Non-technical buyers wanting a point-and-click dashboard . it's an API	Businesses needing SLAs or guaranteed accuracy
Privacy	Brinztech reported a leaked 2.55 GB database; a DPA is published, but no dedicated security page was found.^⁹	No known public vulnerabilities found in the sources reviewed.
Support quality	Solo founder, but visibly responsive on Reddit	No evidence found
Public sentiment	Developers describe it as a fast, accurate IP API with a useful free tier, and the solo founder is unusually visible and engaged online.^⁶	Users know it mainly as a free alternative to paid IP APIs, and most visible commentary traces back to the developer's own posts.¹¹
Biggest gotcha	Verify the leaked-database report before relying on it for IP-based security blocking^⁹	No independent reviews found; nearly all visibility is self-promotion.
