Free proxy checks for marketing and e-commerce teams
Confirm which IP and location your team is really using, catch leaks before a market check goes wrong, and test proxy credentials before you hand them to a colleague. Every tool is free and works without an account.
Connection & identity
My IP
Shows the public IP sites receive from you, plus the hostname behind it and your browser string.
IP location lookup
Country, city, ISP and ASN for any IP - check an exit IP sits in the right market.
User-Agent checker
Find out which browser, OS and device type your requests announce.
HTTP headers checker
Review the headers a website receives, from language settings to proxy headers.
Anonymity & leaks
Anonymity checker
Scores your browser request on proxy headers, User-Agent, language and network type.
WebRTC leak test
Spot WebRTC handing your office or home IP to the sites your team checks through a proxy.
DNS leak test
Fire test lookups and compare where DNS resolves with where your traffic exits.
Browser fingerprint
Fonts, canvas output and hardware details that can tie separate browser profiles to one device.
Proxy & network
Proxy checker
Test one proxy before you share it: response, round-trip time and exit IP.
Blacklist checker
When emails bounce or forms fail, check whether Spamhaus, Barracuda or other blocklists list an IPv4 address.
Port scanner
Confirm a company server answers only on the common TCP ports you expect.
Ping
Measure how quickly a proxy gateway or host accepts connections from our server.
Built for the checks teams repeat every week
Marketing, e-commerce and research teams that buy proxies from us ask the same three things before a job starts. Is the proxy connected? Does the site see the right location? Is anything still pointing back to the office network?
Rather than send you to a mix of third-party sites, we put the answers in one place: free, without ads, and focused on the checks that matter when proxies support client work, ad reviews or price monitoring.
Nobody has to log in, nothing you check is saved, and your data is never sold. If the tools become part of your team's routine, our paid plans start from $3.50 per GB, run on a 99.9% uptime network and support HTTP, HTTPS and SOCKS5 from the first connection.
Five checks before new proxies reach a client project
New credentials on their way into a rank tracker, an ad-review tool or a price monitor? Run these five checks first. They take about two minutes and can save your team a support ticket later.
-
1
Note the IP you start from
Before anyone switches the proxy on, open My IP and record the address. It belongs to your office or home line, and it is the one the sites you research should stop seeing.
-
2
Test the credentials
Enter the host, port and login in the proxy checker. It reports whether the proxy responded, how long the round trip took and which exit IP the request left from.
-
3
Confirm the switch took effect
Repeat the check from inside the browser or tool your team will really use, with the proxy on. If My IP still shows the address from step 1, that tool isn’t using the proxy yet. A new address means it is; confirm its country in the IP location lookup.
-
4
Check what the request gives away
The anonymity checker grades what your browser’s request reveals, from headers to the User-Agent. Leaks inside the browser are outside its view, so follow it with the DNS and WebRTC leak tests.
-
5
Time the route
Put your gateway’s host and port into Ping to see how fast it accepts connections from our server. The port scanner checks the common ports on any public host your company manages.
What a website learns before the page loads
When someone on your team opens a competitor’s product page or checks an ad placement, the site sees the IP address the request came from. That address is enough for the site to estimate the visitor’s location, internet provider and network (ASN). A proxy puts one of our IPs in place of yours, so the site responds as it would to a visitor in the proxy’s location.
Sites also read what the browser says about itself: headers, a language preference, a time zone and more. When those disagree with the IP, the page you get may not be the one a local customer sees: a different language, say, or prices in another currency. The anonymity checker scores your request headers and the type of network your IP belongs to, so the obvious mismatches show up in seconds.
Which tool to open next depends on the job. Reviewing a mobile campaign? The User-Agent checker confirms you are presenting a phone browser. Wrong language on a price page? The HTTP headers checker reveals which Accept-Language your browser sends. Running several client profiles? Open the browser fingerprint tool in each to see the fonts, graphics output and hardware details that could tie them together, even without cookies.
When the office network shows through
Sometimes part of a visit skips the proxy and leaves over your own connection. For a business, that can show your office network to the sites you research and make location-based checks unreliable. Two browser functions, DNS and WebRTC, account for most cases.
Lookups that skip the proxy
Before a page loads, the device asks a DNS resolver for the site’s IP address. If that lookup uses your own connection, your provider’s resolver sees every domain your team checks, and you may be sent to servers chosen for your region rather than the proxy’s.
Run our DNS leak test and your browser makes a set of test lookups; the page then explains how to match the resolvers that answered against the location your traffic exits from.
Browsers that reveal your IP
WebRTC is the browser feature behind video calls and live chat. To link callers directly it gathers the device’s addresses, on the local network and on the internet, and any page you open can read them with a few lines of JavaScript, outside the proxy.
If the WebRTC leak test finds an address handed out this way, switch WebRTC off or ask IT for a browser policy before the next research task.
Running them is safe on a work laptop: they read and report, and leave every setting on the device and in your proxy plan as it was.
Why an IP’s history affects everyday tasks
IP addresses carry a history. Blocklist operators, Spamhaus and Barracuda among them, record addresses involved in spam or abuse, and email systems along with certain websites consult those lists before letting traffic in. When a sign-up confirmation never arrives, or a form submission is refused without explanation, a listed IP is a common cause.
Our blacklist checker runs one IPv4 address past several DNS-based blocklists at once and marks each one listed or clean. Run your exit IPs through it before an important task. Free proxy lists are far more likely to include addresses with a poor history, which is one reason teams pay for their proxies instead.

Before you open a support ticket
When a proxy misbehaves halfway through a client job, start from the symptom. The linked check usually shows where the fault sits, and if you still need our support team, your results give them a head start.
The tool won’t connect
Copy the host and port straight from your dashboard, not from an old email or shared spreadsheet. Then test them in the proxy checker and ping the gateway. The port scanner lists which common ports the host answers on.
Login details are refused
Re-enter the login saved in the tool. If the order uses IP-whitelist access instead, the office or server address has to be on the list in your dashboard. Then confirm the tool is set to the protocol you picked: HTTP, HTTPS or SOCKS5.
The office IP still shows
Often the proxy is set in a different browser profile or app from the one being tested. Reload My IP in the exact tool your colleague uses. Once the exit IP shows there, the anonymity checker reviews the request, and the leak tests for DNS and WebRTC pick up anything that slips around the proxy.
A site shows the wrong market
The IP location lookup shows which country most sites will assume for the exit IP. Its data can lag when address blocks change hands, so a wrong country is sometimes the database’s error rather than the proxy’s. If the country is right and the page still isn’t, check the language your browser sends in the HTTP headers checker.
Forms or confirmation emails fail
Look up the exit IP in the blacklist checker. A spam listing often lies behind refusals that seem to come from the site or from the account itself.
Pages load slowly or unevenly
Ping times the connection from our server to your gateway. A faraway exit adds delay through distance alone. If delays jump around on a nearby exit, send your Ping results to support.
Plain definitions to share with colleagues
- IP address
- Your connection’s public address. Many sites use it to choose the country version, language or currency they show.
- ASN
- The number that identifies a network on the internet (autonomous system number). It tells you whether an address belongs to home broadband, a mobile network or a hosting firm.
- Proxy
- An intermediary server. Your team’s requests go out through it, and the sites they reach record its address, not the office connection.
- SOCKS5
- A proxy protocol that carries more than web pages, which suits desktop software and apps. Alongside HTTP and HTTPS, it comes with every one of our plans.
- DNS
- The internet’s naming system (Domain Name System). It turns a site name such as example.com into the IP address the browser connects to.
- WebRTC
- The browser technology behind video calls and live chat. It can also pass the device’s own addresses, local and public, to whatever page is open.
- rDNS (reverse DNS)
- Translates an IP address back into a hostname. The name frequently reveals the provider, such as a broadband company or a cloud host.
- User-Agent
- The header in which a browser introduces itself: its name, version and operating system, and often the device type.
- Browser fingerprint
- Fonts, screen size, graphics output and other device details, combined into a profile a site can recognise without cookies.
- Blocklist (blacklist)
- A published register of addresses reported for spam or abuse. Email systems and some websites look it up before letting traffic through.
- Latency
- The round-trip delay to a host and back, measured in milliseconds. Lower figures mean pages respond faster.
- Rotating proxy
- Changes the exit IP automatically, either with each request or on a timer. Our guide explains how rotating proxies work.
Where your team’s inputs go
Each result is put together for your screen and then discarded. We don’t store the IP addresses you look up, the proxy credentials you test or the leak results on your screen, so there is nothing to export, delete or opt out of. A few checks do need an outside source to answer: the location lookup queries ip-api.com, each blocklist receives a DNS query from the blacklist checker, and the proxy checker requests a public IP-echo service through your proxy. For the WebRTC test, your browser itself contacts a STUN server on the public internet.
The same principle covers our paid proxies: we keep no logs of the traffic your team sends through them, which matters when the research you run belongs to a client.

Questions from team leads and buyers
Is there a cost to using the tools across our team?
No. Anyone on your team can use every tool here as often as needed, with no login, sign-up or ads. The tools are paid for by our proxy sales.
Does each colleague need an account?
No. Anyone with the link can use them. Accounts matter only once your team buys proxies, so that orders and credentials sit in one dashboard.
Is anything we check stored or shared?
We keep no log of the IPs, proxies or results your team works with; they appear on screen and are then discarded. A few checks need an outside source to answer, as the privacy note above explains.
What does a low anonymity score say about our setup?
Points come off for what the request itself reveals: headers added by a proxy, a missing or script-style User-Agent, no language preference, a generic Accept header, or a reverse DNS name belonging to a cloud provider. DNS and WebRTC are outside its view, so pair it with the DNS and WebRTC leak tests.
Can we use your proxies in the software we already have?
Every paid plan supports HTTP, HTTPS and SOCKS5, which covers browsers, rank trackers, price monitors and most marketing tools with proxy support.
How is proxy use billed and paid for?
Billing follows the data your team uses, starting from $3.50 per GB, and network uptime stands at 99.9%. You can pay by card through Stripe or in crypto through Cryptomus, and the pricing page shows the per-GB rate of every proxy type.
Proxies your team can check before every job
