Cloudflare Radar URL Scanner review
A free URL scanner with detailed reports, but no file or computer scanning.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Cloudflare Radar URL Scanner analyzes submitted URLs and creates reports for people investigating webpage security and behavior. It is available on the web and through an API, and suits users who want to inspect a page’s verdicts, infrastructure, redirects, and diagnostics without installing an antivirus scanner. Reports can be publicly shareable, while API submissions can set report visibility to unlisted.
The scanner’s depth is in webpage inspection. Reports can include malicious-content verdicts and phishing information alongside redirect history, contacted IP addresses, ASNs, domains, certificates, cookies, page requests, console output, performance timings, and detected technologies. Search can locate scans by URL, domain, IP address, ASN, filename, or resource hash. This makes it useful for investigating a suspicious link or understanding what a website loads and contacts. It is not a file scanner or an on-demand computer antivirus scanner, so users who need to scan downloads or a device should choose a product with those capabilities instead.
Radar API is documented as free, and the product is described as free. API use requires a URL Scanner-specific API token. Its cloud deployment and web access make it a focused option for URL investigations, while the API supports custom scans and unlisted reports. Choose it when detailed URL reports and search across scan results are the priority; do not treat it as a substitute for file or endpoint protection. Its narrow scope is a defining boundary, not a replacement for broader malware analysis.
