FAQ
Is IPLogs a free alternative to Spur?
For VPN, proxy, Tor, and datacenter detection, yes — IPLogs is free, needs no signup, and returns every matching signal. Spur, however, leads on residential-proxy detection specifically, which is its specialty; IPLogs flags known residential-proxy backbones but does not match Spur's depth there.
Which is better at residential proxy detection?
Spur. It specializes in residential-proxy and proxy-network attribution and tracks hundreds of millions of anonymized IPs. IPLogs flags traffic on known residential-proxy backbone networks (Webshare, Bright Data, IPRoyal, Oxylabs) but does not reverse-engineer proxy networks the way Spur does.
Does IPLogs require signup like Spur?
No. IPLogs has no signup or API key and an unlimited fair-use free tier. Spur is a paid, enterprise-oriented product that requires an account.
