projectdiscovery/cdncheck — A utility to detect various technology for a given IP address.

Description and use

projectdiscovery/cdncheck is an open‑source command‑line utility that scans a target IP address to identify the CDN, WAF, DNS, and other infrastructure technologies it’s using. It aggregates data from multiple public sources and fingerprinting techniques, providing quick, reliable detection for security researchers and DevOps teams. The tool is lightweight, easy to integrate into automated workflows, and is actively maintained as part of the ProjectDiscovery suite.

Problem

projectdiscovery/cdncheck helps teams reuse service infrastructure instead of rebuilding common backend pieces.

Outcome

Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.

Workflow

• ship API services faster
• reuse backend infrastructure
• standardize service patterns

Evidence
