Free Network Tools

Diagnostics tools, free to use

A small set of free utilities for everyday network checks — verify a proxy list, measure latency to a host, trace the network path, or look up your own IP. No signup, no installs.

Proxy Checker

Test up to 500 HTTP, HTTPS, SOCKS4 or SOCKS5 proxies and see which ones are alive.

Port Scanner

Check which ports from a curated list of common services are reachable on a given host.

Ping

Measure round-trip latency to any IP or hostname. Helpful before pointing traffic somewhere.

Traceroute

See every hop between us and the target host, with country and ASN per router when known.

My IP

See your public IP, network operator, country, browser, and request headers in one place.

Why we built these

Most network checks shouldn’t require installing a CLI or signing up for a SaaS dashboard. The five tools here cover the questions we most often answer in support chats — is this proxy alive, is that host reachable, where is my traffic going, what does my IP look like to the outside world. Each tool runs the check from our infrastructure and shows you the result, with strict per-IP rate limits and reserved-range protections so the utilities can’t be abused for scanning random networks.

How the tools stay safe to share publicly

Rate limited per IP

Each tool has a small per-minute budget so a single visitor can’t saturate the workers.

Private ranges blocked

Lookups that resolve to RFC1918, link-local, loopback, or cloud-metadata addresses are refused.

Bot screening

An invisible Cloudflare Turnstile widget validates the request before any work is dispatched.

No credential retention

Submitted proxy lists are processed in memory and discarded as soon as the response is finished.

Frequently asked questions

Are these tools really free?

Yes. Every tool on this page is free to use without an account. Per-IP limits keep them from being abused, but everyday checks fit comfortably within those limits.

Do you store the proxies I paste?

No. The proxy checker processes lists in memory and discards them after the response is sent. Nothing is logged to disk.

Why does the port scanner only check a fixed list of ports?

Allowing arbitrary port ranges would turn this into a generic scanner usable against random infrastructure. We restrict the tool to a short curated list so it remains useful for verifying a server’s common services without enabling abuse.

Can I run these against private networks like 192.168.x.x?

No. Hosts that resolve to RFC1918, loopback, link-local, or cloud-metadata addresses are refused. Private network checks belong on tools that run inside that network, not on a public service.

Why ask Cloudflare Turnstile to verify my browser?

Turnstile is an invisible bot screen that runs in the background. It keeps automated abuse low and is the reason we can offer the tools without forcing a signup or CAPTCHA.

Need real proxies after testing?

If the diagnostics here did the job, our paid plans give you 105M+ residential IPs across 195 countries.
