Duck Connect vs Zetta Link

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. 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 The account keeps only what it needs to work: your sign-in email or ID, your subscription status and an install identifier, so the account stays after you reinstall the app.

Zetta routes your iPhone's traffic through the proxy servers in your subscription, following the rules you set. SUBSCRIPTIONS • Paste a subscription URL and Zetta parses the server list. • Keep several subscriptions and switch between them with a tap. • Each subscription can refresh on its own schedule. ROUTING • Rule mode sends mainland China domains and IPs direct and everything else through the server. Global mode sends everything through the server. • Add your own rules: domain, domain suffix, keyword, IP range. • Type a domain to see which rule it would hit before you connect. CONNECTION • Live upload and download speed, connection time, and the last 60 seconds as a chart. • Test server latency before connecting. • A widget on the Home Screen and Lock Screen shows the connection state. • Siri and Shortcuts: "Turn on Zetta", "Zetta connect to Tokyo 01". PRIVACY • No account and no sign-up. Subscription URLs stay on your device. • Zetta has no servers of its own and sends nothing anywhere except to the servers in your subscription. Zetta needs a subscription from a proxy provider. It does not include one.
