About

Duck Connect

Features
Read full description

DuckConnect turns a configuration you already have into a working connection. Paste the link, pick an endpoint, tap once โ€” protocol handling and routing are the app's job, not yours. Works with any provider. The app ships no servers and no access of its own: point it at a subscription link or a single configuration and it reads whatever comes back โ€” a server list or one endpoint, plain text or base64 โ€” applying the routing rules exactly as they were written. The app itself is free and contains no in-app purchases. What you connect through is entirely up to you. Key features: โ€ข Modern protocols, including VLESS and REALITY โ€ข Compatibility with XTLS-based configurations โ€ข Import by link, QR code, or clipboard โ€ข Built on the v2ray/xray core โ€ข Endpoint list with live response times โ€ข Live download and upload speed with a session timer โ€ข Automatic refresh, so new endpoints appear on their own โ€ข One-tap connection management โ€ข Light and dark themes No accounts and no sign-up. Configurations are stored on the device only; the app collects no personal data and contains no ads, analytics or tracking SDKs.
