SSPRO Config Lab vs Duck Connect

SSPRO Config Lab is a local workspace for user-provided proxy/VPN configurations. It does not provide nodes or hosted network service. It helps you preflight subscriptions before installing VPN permission, parse Clash YAML, sing-box JSON, or single-node links, and inspect profiles, policies, nodes, rule tests, DNS/Trace/log diagnostics, and release readiness on device. Lifetime Pro unlocks local advanced workflows and diagnostics only; SSPRO does not provide or sell proxy nodes, VPN servers, hosted network services, traffic, or bandwidth.

DuckConnect turns a configuration you already have into a working connection. Paste the link, pick an endpoint, tap once — 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 — a server list or one endpoint, plain text or base64 — 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: • Modern protocols, including VLESS and REALITY • Compatibility with XTLS-based configurations • Import by link, QR code, or clipboard • Built on the v2ray/xray core • Endpoint list with live response times • Live download and upload speed with a session timer • Automatic refresh, so new endpoints appear on their own • One-tap connection management • 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.
