SSPRO Config Lab vs Zetta Link

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.

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.
