Website Technology Inspector

Investigate any URL to reveal the technologies powering it. Detects web servers (Nginx, Apache, IIS), CMS platforms (WordPress, Shopify, Squarespace, Drupal), CDN and proxy services (Cloudflare, Fastly, Akamai), frontend frameworks (React, Vue, Next.js), analytics tools, and hosting provider via ASN lookup. Uses a self-hosted fingerprint database with no external API dependencies.
