Free Link Checker & URL Scanner — Is This Link Safe?

IncogSay is a premium cybersecurity platform providing zero-trust link auditing and email domain authentication tools. Built entirely on Cloudflare Workers edge infrastructure with 100% privacy guarantee and zero data logging.

IncogSay features two dedicated products: Cyber Link Auditor (for URL scanning, redirect chains, QR codes, and SSL analysis) and Email Trust Radar (for SPF, DKIM, DMARC, BIMI, and header analysis). Keeping them in standalone experiences provides a focused, uncluttered workflow for security teams and users.

No. IncogSay operates under a strict zero-retention policy. All analysis runs statelessly in your browser session or through ephemeral Cloudflare Workers. We do not maintain databases, logging servers, or user tracking cookies.

Yes. All diagnostic tools, generators, and threat scanners on IncogSay are completely free with no account signup required.

Most threat scans and DNS lookups complete in under 10 milliseconds thanks to Cloudflare's global edge network across 300+ cities.

A redirect chain checker traces every HTTP hop a URL makes before reaching its final destination. It reveals 301/302 redirects, detects redirect loops, and exposes hidden intermediary domains that may indicate tracking, affiliate cloaking, or phishing. IncogSay's redirect chain tool shows each hop with status codes so you can instantly see the full redirect path.

Copy the URL without clicking it and paste it into IncogSay's free safe link checker. Our tool scans for phishing signals, typosquatted domains, suspicious redirect chains, and SSL certificate issues — giving you a clear safety verdict in seconds. Never visit a suspicious link directly; always check it first.

A URL scanner is an online tool that inspects a web address for security threats without you having to visit it. IncogSay's URL scanner analyzes domain structure, redirect chains, SSL validity, domain age, entropy patterns, and homograph spoofing signals to produce a comprehensive threat verdict.

Enter any domain into IncogSay's free domain age checker. It performs a live RDAP/WHOIS lookup to show when the domain was first registered, last updated, and when it expires. Newly registered domains (less than 30 days old) paired with professional-looking sites are a major phishing red flag.

A DKIM checker validates that your domain's DomainKeys Identified Mail (DKIM) public key record is correctly published in DNS. IncogSay's free DKIM checker requires your domain and DKIM selector to look up the TXT record, verify the key format, and confirm your outgoing emails will authenticate properly with receiving mail servers.

BIMI (Brand Indicators for Message Identification) allows your verified brand logo to appear next to your emails in Gmail, Yahoo, and other supporting inboxes. IncogSay's free BIMI checker looks up your _bimi DNS record, validates the SVG logo URL, checks VMC certificate requirements, and verifies your DMARC enforcement is at p=quarantine or p=reject — a prerequisite for BIMI.

Yes. IncogSay's redirect tracker follows every HTTP redirect hop, revealing intermediary URLs that may be used for affiliate cloaking, ad tracking, or phishing redirects. This is especially useful for checking link redirect chains in email marketing campaigns, affiliate links, and URL shorteners like bit.ly.

IncogSay's Cyber Link Auditor can check any individual link's safety, redirect path, and SSL status for free. For bulk inbound link checks across your entire website, you can audit individual suspicious backlinks one by one through our free online link checker — no account or download required.

IncogSay's phishing site detection engine uses six parallel analysis phases: domain homograph detection (Punycode/Unicode spoofing), Shannon entropy scoring for DGA-generated domains, Levenshtein distance for typosquatting, live MX DNS probing, redirect chain expansion, and SSL certificate validity checks — all running in under 50ms on Cloudflare's global edge network.

An SSL certificate checker verifies that a website's HTTPS certificate is valid, not expired, issued by a trusted Certificate Authority, and matches the domain you're visiting. IncogSay's free SSL checker shows certificate expiration dates, issuer details, and flags any common SSL misconfigurations that could expose visitors to man-in-the-middle attacks.

A link spam checker analyzes URLs for spam signals including blacklisted domains, suspicious redirect chains, low-quality hosting, and malware markers. IncogSay's URL scanner functions as a free spam link checker — paste any URL to check if it's flagged as a spam link, spam URL, or otherwise dangerous. Use it to check website spam links, verify outgoing links before publishing, or audit links inside emails before clicking. You can also check spam URLs one by one to protect yourself from URL spam in messages.

To check incoming links or backlinks to your website via Google, use Google Search Console's 'Links' report. For checking inbound links from Google's perspective, search for 'site:yourdomain.com' or use GSC's 'Links to your site' section. IncogSay's link checker can audit individual backlinks for safety. Tools like the Racoon SEO link checker, Ahrefs, and Semrush are also popular SEO link checkers and backward link checker tools for bulk inbound link analysis. For a simple Google backward link check or to see check links to your website, GSC is the free standard.

A URL analyzer performs deep analysis of a URL's structure, parameters, redirect chain, and domain signals — answering questions like 'analyze this URL', 'what does this link do?', or 'inspect this link'. URL analyzers often show detailed breakdown of URL components (protocol, domain, path, parameters), while a URL scanner focuses on delivering a threat verdict. IncogSay's tool functions as both a free URL analyzer and a URL scanner — paste any link to analyze URL structure, inspect links, identify a link's destination, and detect any threats.

Yes. Email link checkers are essential because phishing links in emails are the #1 attack vector in cybersecurity. To check a link in an email: copy the URL from the email (do not click), paste it into IncogSay's free email link checker / URL scanner, and review the safety verdict. This works for checking links in email messages, checking email links automatically as part of your security workflow, and verifying phishing email links before opening them. IncogSay also supports checking email header traces for advanced investigation.

A link identifier (also called a link detector or link inspector) is a tool that identifies what a URL actually is and where it leads without you clicking it. IncogSay's link identifier/link inspector analyzes: the actual destination domain (not just the display text), full redirect chain, link type (shortened link, tracking link, phishing link, IP-only URL, or legitimate URL), domain age, and SSL status. Use it to identify links, detect suspicious links, verify what a link is, and inspect any URL before opening it.

To check website trustworthiness and verify if a site is a scam or reputable: (1) Use IncogSay's domain age checker — scam sites are almost always on newly registered domains. (2) Run the URL through IncogSay's free URL scanner to check for phishing site detection signals. (3) Check the SSL certificate with our SSL checker. (4) Verify the redirect chain with our redirect checker. These four checks together give you a comprehensive website trust assessment. Tools like IncogSay work as a website trustworthiness checker, website risk checker, reliable site checker, reputable website checker, and site verifier all in one.

Yes. IncogSay's QR URL scanner lets you upload a QR code image and it will extract the encoded URL and run a full safety scan on it. This is the safest way to check QR code links — instead of scanning with your phone and opening the link immediately, you first extract the URL from the QR code and verify it's safe. Use it as a QR code URL scanner, QR URL extractor, or to get the URL from a QR code before scanning it on your mobile device.

IP grabber links are URLs that record your IP address and device info when you visit them. IncogSay's URL scanner can detect suspicious IP-grabber patterns, fraud links, and tracking URLs by analyzing: bare IP addresses in the URL, known grabify/iplogger domain patterns, suspicious redirect chains to logging services, and URL entropy analysis. Use IncogSay's free link checker to check if a link is an IP grabber, fraud link, malicious link, or hack link before clicking — especially important for Discord links, gaming community links, and social media DM links.
