An ipapi.is alternative for VPN and proxy detection

ipapi.is names the VPN behind an address, but has no residential proxy flag: its own docs say is_proxy misses most home and phone proxies. VPNDetection answers residential, mobile, datacenter and public proxies on every paid plan, each with first and last seen, from $19 a month for 250,000 lookups.

ipapi.is's figures are from its home page and its VPN database page, last updated on 2026-11-12. Ours are counted from 2026-11-13's build of the data every lookup answers from. No independent list of every VPN address exists to test the APIs against, so each count is the company's own.

Where ipapi.is does more

ipapi.is is cheaper at volume: Basic is $20 a month for 20,000 requests a day. Its answer also carries data outside VPN detection: abuse scores for the network and its AS, crawler names, satellite and anycast flags, and where a VPN's exit really is against the country it claims.

For proxy detection it stops at public lists. Ours answers the proxies ipapi.is can't, residential, mobile and datacenter, each with first and last seen and how many providers resell the address, puts a confidence on every VPN match, and takes batches of 1,000 against its 100.
