Websites Built with Yii
We have not detected websites built with Yii yet. Our detection engine continuously scans new websites. Once sites using this technology are discovered they will appear here automatically.
About Yii
Yii is a PHP framework for web applications and admin back ends. Detection relies on the assets and CSRF field its default setup publishes. A Yii site is also reported as PHP.
- yii.js and yii.activeForm.js under /assets/<hash>/
- CSRF field `YII_CSRF_TOKEN`, `_csrf-frontend` or `_csrf-backend`
- Matching cookies
- Not detectable when no Yii front-end assets are loaded
How We Detect Yii
Our scanner identifies Yii usage through the following signals:
- Script URLs or inline script content matching "/assets/[0-9a-f]{6,}/yii(.[a-z]+)?.js", "yii.(activeForm|validation).js" (high-confidence tier)
- HTML structure patterns such as "name=["'](YII_CSRF_TOKEN|_csrf-(frontend|backend))["']" (medium-confidence tier)
- Cookies named like "YII_CSRF_TOKEN", "_csrf-(frontend|backend)" (medium-confidence tier)
- Signal weights for Yii: 85 points per high-tier match, 55 per medium, 25 per low — a site needs 60+ points before Yii is reported.
