Cloudflare-Bypass

Note: For devices running Android API level 30 or lower, it is recommended to specify a custom userAgent in the WebView settings to prevent being blocked by outdated browser warnings.

Cloudflare-Bypass is an Android library designed to seamlessly bypass Cloudflare's anti-bot protection using a custom WebViewClient. This library allows developers to load websites protected by Cloudflare's challenge without needing manual user intervention.
