Product shape

Route, inspect, and change network behavior in one place.

Link1 keeps the pieces you usually manage separately in the same place: routing rules, provider updates, proxy groups, DNS, TUN, HTTP handling, and the runtime state needed to debug them. It is designed for always-on desktops, servers, and router-class hardware.

Policy routing

Match by process, domain, IP range, rule provider, inbound context, and fallback order.

Protocol adapters

Bring Shadowsocks, VMess, VLESS, Trojan, Hysteria2, TUIC, WireGuard, Tailscale, OpenVPN, AnyTLS, and more into one routing model.

Local network control

Manage HTTP/Mixed entry, system proxy, DNS nameservers, fake-IP behavior, and TUN routing.

Flow diagnostics

Follow active connections from device and process to matched rule, policy chain, and exit node.

Performance core

Built for high-throughput routing with tight memory budgets on always-on devices.

HTTP engine

Use mock, rewrite, route, JSON/JQ transform, script hooks, capture, and MITM when explicitly configured.

Interface preview

Built around the daily routing loop.

Select policy groups, compare node health, inspect active flows, test rules, and read runtime logs without leaving the app.

Proxy group workspace showing selected routes, latency, protocol labels, and node health. — **Policy groups and exits** Compare groups, latency, protocol labels, provider source, and fallback state before switching.

Connection inspector showing active hosts, matched rules, selected policy, and traffic rate. — **Connection trace** Review device, process, target, rule, policy chain, traffic rate, and exit together.

Runtime log viewer showing grouped logs, components, events, and merged details. — **Runtime logs** Keep component events readable while preserving details, repeats, context, and ordering.

Coming soon

A new network workbench is taking shape.

Link1 is coming soon. We are preparing a focused release for users who want more control over routing, diagnostics, and local network behavior.
