VPN & Proxy Detection
Check whether an IP address is a VPN, proxy, Tor exit node, or datacenter connection.
# free & rate-limited · no signup · live results from the same engine as the API
Since the engine is the same one the API runs, a key does not buy you a better answer. It buys volume, bulk jobs and a signed receipt.

FAQ
Is this VPN and proxy detection tool free?
Yes. Guests get 5 lookups a minute and 50 a day, no signup. A free account has 200 credits a month, no card, and core validations cost 1 credit each.
How accurate are the results?
The free tool runs the same engine as the API, so what you see here is what an integration returns. Where we cannot determine something we say so rather than guessing — a confident wrong answer is worse than an honest gap.
Can I use this in bulk or via API?
Yes. Paste 20 numbers with no account, or sign in and clean 100 a month on the free plan. Paid plans take longer lists, CSV jobs, webhooks and higher rate limits, from $3.16 per 1,000 core lookups.
