SniffTest vs ScamAdviser vs URLVoid: which free scam checker should you use?

You have a suspicious link and you want to check it before clicking. Three free tools come up repeatedly: SniffTest, ScamAdviser, and URLVoid. All three are free, require no account, and return some kind of verdict. But they work very differently.

SniffTest

doasnifftest.com · Free · No account · No URL storage

SniffTest runs 17 checks in parallel and returns a risk score from 0 to 100 with a plain-English verdict - not a raw data dump, but an actual interpretation: "This looks like a phishing site" or "This appears to be a legitimate, established retailer."

The checks cover domain age, Google Safe Browsing, fraud intelligence (IPQualityScore), community-reported scam blocklists, HTTPS and TLS status, domain pattern analysis (typosquats, phishing keywords in the URL path), brand impersonation detection, review reputation, infrastructure signals, and page content - including pressure tactics and unusual payment methods.

SniffTest also handles QR codes: scan with your camera or upload an image. None of the major alternatives offer this.

Privacy-wise, nothing is stored by default. URLs are not logged, no account is required, no tracking cookies. The only thing saved is an anonymous result snapshot if you explicitly choose to share your result with someone.

Best for: Anyone who received a suspicious link, text, or QR code and wants a fast, clear answer. Also the best option for checking an online shop before buying.

ScamAdviser

scamadviser.com · Free · No account required · Ad-supported

ScamAdviser has been running since 2012 and has built up a large database of domain reputations. It aggregates data from 40+ sources - registration records, traffic patterns, hosting details, SSL certificates, and its own historical data - and returns a trust score between 0 and 100.

The output is data-rich but requires interpretation. You get a score, a breakdown of contributing factors, and links to community reports and related reviews. The depth is useful for thorough investigation, but the result page is significantly more technical than a plain-English verdict. It also carries advertising around the results.

Best for: Researching a domain you want to understand in depth - particularly useful for its historical reputation data and breadth of aggregated sources.

URLVoid

urlvoid.com · Free · No account required · Ad-supported

URLVoid is a blocklist aggregator. It checks a domain against 30+ security engines - including VirusTotal, Google Safe Browsing, PhishTank, and OpenPhish - and shows a pass/fail for each. There's no synthesised verdict, no plain-English explanation, and no analysis of the domain itself beyond what's already in those databases.

A brand-new scam domain that hasn't been reported yet will come back clean. URLVoid is genuinely useful as a second check - if another tool flags something, URLVoid tells you whether the major security databases have caught it yet.

Best for: Technical users who want to cross-reference a domain against multiple established security databases, or as a follow-up check after another tool flags a result.

Which should you use?

For most people in most situations - a text from an unknown number, a deal that seems too good, an online shop you haven't heard of - SniffTest gives you the answer you need in the least amount of time.

For deep research into a domain's history, ScamAdviser's breadth is more useful. And if you want to know whether the major security databases have already flagged something, add URLVoid as a cross-reference. The three tools are complementary, not competing.

Frequently asked questions

Q: Is SniffTest better than ScamAdviser?

A: They serve slightly different purposes. SniffTest is built for consumers who want a plain-English answer fast - it analyses the URL itself, including its content and infrastructure, not just its historical reputation. ScamAdviser has a larger historical database and is more useful for in-depth domain research. For most everyday checks, SniffTest gives a clearer, faster answer.

Q: Does URLVoid detect new scam sites?

A: Not reliably. URLVoid checks against existing blocklists, so a domain registered last week that has not been reported yet will likely come back clean. Tools that analyse the domain itself - its age, content, and infrastructure - are better at catching new scam sites before the databases catch up. SniffTest's domain age and content checks are specifically designed for this gap.

Q: Are these tools 100% accurate?

A: No tool is. Any checker can miss a brand-new scam site or occasionally flag a legitimate one. Use a checker as one input, not the only one. If a tool flags something as high risk, that is a strong signal to avoid it. If it comes back clean but other warning signs are present - prices that seem impossible, no real contact details, a very new domain - trust those signals too.

Q: Is it safe to paste a URL into a scam checker?

A: Yes. Pasting a URL into a checker does not open the site or expose you to any risk. SniffTest specifically does not store or log the URLs you check, so there is no privacy concern. You are asking the tool to look up information about a domain - no different from searching for a company name.

Q: What if a site passes all checks but still looks suspicious?

A: Trust your instincts. A clean result means no known red flags were found - it does not guarantee the site is safe, particularly if it is brand new. If prices are far below retail, there are no real contact details, or payment is only accepted via bank transfer or crypto, those are warning signs regardless of what a checker says.
