Black Fox Config Builder

Black Fox Config Builder is a lightweight, high-performance management tool designed for 3X-UI panel administrators. It streamlines client creation, config generation, and subscription handling directly from your Android device—eliminating the need to navigate the web panel interface manually.

Please Note: This application is an administrative client and does not embed a local VPN core. It connects directly to your remote 3X-UI panel to manage accounts and credentials.

Key Features:

• Fast & Secure Connection: Authenticate seamlessly to your 3X-UI panel. Sensitive credentials and cookies are safely encrypted using hardware-backed Android Secure Storage.

• Single Client Issuance: Easily create clients with custom or auto-generated names, flexible traffic quotas (GB), custom expiry periods (days), and targeted inbounds.

• Bulk Config Generator: Generate dozens of client configurations in batch mode with customizable remark patterns within seconds.

• Instant QR Code & Links: Display high-resolution QR codes for immediate device scanning, with one-tap copying for direct connection links and subscription URLs.

• Local Records & Management: Maintain a structured history of all created configurations, filter records, copy credentials, or delete clients directly from the remote panel.

• Export & Sharing: Export generated configs in multiple formats (TXT, CSV, JSON, Subscription links) for hassle-free customer delivery.

• Native Core Performance: Powered by an optimized Go network engine for lightning-fast API transactions and minimal battery consumption.
