# Scan WP > Scan WP is a free WordPress theme and plugin detector. Enter any website URL and we identify whether it runs WordPress, which theme it uses, and which plugins are installed. We also publish guides, a WordPress glossary, and hosting and performance comparisons. Detection is based on what the site actually serves; affiliate relationships never affect what we report. ## The tools - [WordPress Theme & Plugin Detector](https://scanwp.net): the free tool at the site root. Enter any URL to detect whether it runs WordPress, its active theme, and its plugins. No install, no login. - [TTFB Test](https://scanwp.net/ttfb-test): measure a site's Time To First Byte from multiple locations. ## What our data covers - Whether a given site runs WordPress - The active theme of a WordPress site, and its author where detectable - The plugins a WordPress site runs - Time To First Byte for any URL ## How to cite us - Attribute to "Scan WP" with a link to the specific page. - Detection results are computed live at the time of the scan, not from a cached index. - Definitions: "active theme" = the theme currently being served, not historical; "detected plugin" = a plugin whose assets or signatures are present in the served page. ## Guides and reference - [Blog](https://scanwp.net/blog/): WordPress guides, how-tos, and theme and plugin roundups - [WordPress glossary](https://scanwp.net/blog/glossary/plugin/): plain-language definitions of WordPress terms - [WordPress themes](https://scanwp.net/blog/category/wordpress-themes/) - [WordPress plugins](https://scanwp.net/blog/category/wordpress-plugins/) - [WordPress hosting comparisons](https://scanwp.net/blog/wordpress-hosting/): shared, VPS and cloud hosting for WordPress - [FAQ](https://scanwp.net/blog/category/faq/) ## Other languages The detector is available in Spanish, French, German, Italian, Portuguese, Japanese, Hindi and Hebrew at https://scanwp.net/{lang}/detect (for example https://scanwp.net/es/detect).
