Free tools to test proxies
These free proxy tools let you confirm what your connection and your proxies reveal, before you trust them with real accounts.
No account is required. Most checks run from our server; the WebRTC leak test runs inside your browser. Use them before buying more IPs, to see what a website can learn about your connection, or to find out why a working setup broke.
A sensible order: confirm the proxy responds with the checker or the speed test, look up the exit IP for its country, ASN and whether it reads as datacenter, then run the WebRTC leak test inside the browser profile you actually use, so your real IP never appears beside the proxy IP.
Each result is a snapshot of one moment on our server's network. Re-run a slow or failed check before you draw conclusions.
Your public IP address, as websites see it
What is my IP? This page shows the public IP address every site sees from you right now, explains IPv4 and IPv6, and lets you confirm a proxy profile is active.
Read more →Check proxies in bulk: status, exit IP and latency
Free online proxy checker: paste up to 100 ip:port:user:pass lines and see which proxies work, their exit IP and latency, plus what each failure result means.
Read more →Look up an IP: who owns it, where it is, and what kind of network
Free IP lookup for any IPv4, IPv6 or hostname: see the ASN, ISP, country, city and timezone, and whether the address belongs to a datacenter or a consumer ISP.
Read more →Rewrite a proxy list into the format your tool expects
Convert proxy lists in your browser between ip:port:user:pass, user:pass@ip:port, http:// URLs, SOCKS5 URIs, JSON arrays and FoxyProxy import files, in bulk.
Read more →Check whether WebRTC exposes the IP your proxy should hide
Free WebRTC leak test: compare the IP sites see over HTTP with the IPs your browser reveals through WebRTC STUN, and find out whether your real address leaks.
Read more →Test whether a remote TCP port accepts connections
Free online port checker: test up to 8 TCP ports on any public IP or hostname, see open, refused or timed-out results with handshake time, debug proxy ports.
Read more →Measure how fast a proxy reaches the sites you actually use
Free proxy speed test: measure HTTP(S) response time in ms through one proxy to Google, Facebook, Shopee, Amazon and ipify, and see which targets answer slowly.
Read more →Is this IP on a blocklist? Run a DNSBL reputation check
Free IP blacklist check: look up any public IPv4 in 8 DNS blocklists, including SpamCop, Barracuda, SORBS open-proxy zones, PSBL, UCEPROTECT and s5h.
Read more →Start with one IP and see how it behaves
Sign up at no cost, top up your balance and have a working proxy a few minutes later.
