Features that matter when the network is the bottleneck

Yuanhang is engineered for everyday cross-border use — global node coverage, smart traffic shaping, multi-platform clients, and a privacy-respecting architecture.

Most network accelerators are written for people on stable broadband. Yuanhang is written for the opposite — people who actually need the network to work when conditions are bad. Cellular signal flapping. Hotel Wi-Fi behind three layers of NAT. A long flight followed by a 4G dongle.

The features below aren’t a marketing checklist. Each one solves a real problem we hit during day-to-day cross-border use.

Global node coverage

Yuanhang routes through a curated global network. Nodes are deployed in multiple regions across Asia, North America, and Europe, with a clear preference for regions that have direct peering with major content networks. The point isn’t sheer node count — it’s having the right node nearby when you need it.

For each user session, Yuanhang automatically selects the lowest-latency available path based on real-time measurements. If a node degrades, traffic moves to the next best one without manual intervention.

Smart traffic shaping

Not every request needs to take the same route. Yuanhang’s clients include adaptive traffic shaping that distinguishes between latency-sensitive traffic (video calls, real-time apps) and bulk transfer (file downloads, app updates). Latency-sensitive flows get prioritized routes; bulk transfers get bandwidth-optimized ones.

The result: fewer audio drops on calls, fewer stalled video frames, and a network that feels predictable rather than mysterious.

Cross-platform clients

Yuanhang ships native clients for Android, with Windows, macOS, and Linux versions in active development. A single account works across all your devices. Configuration syncs automatically — set up once, connect from anywhere.

Mobile clients are built with battery and data sensitivity in mind. We pause polling when the app is backgrounded, batch network operations, and minimize wake locks. On a typical day of use, Yuanhang’s foreground impact is comparable to any messaging app.

Privacy-respecting architecture

We do not log browsing activity. We do not track which sites you visit, what data you transfer, or how long you stay connected. The infrastructure is designed so that the operational team — and any external party who might compel disclosure — has no useful records to hand over.

Authentication is per-device. Tokens rotate automatically. If a device is lost or stolen, the session can be revoked from any other signed-in device.

Lightweight by default

The Android APK is under 25 MB. The runtime memory footprint is minimal. We do not ship analytics SDKs that phone home from the client. We do not bundle third-party advertising libraries. The binary that lands on your device is just the network client.

Built for the long session

Most VPN apps assume short, deliberate connections. Yuanhang assumes you keep it on for hours. The persistent-connection codepath is optimized for low idle wakelocks, graceful handover between Wi-Fi and cellular, and automatic reconnection if a network event disrupts the tunnel.

You shouldn’t have to think about whether the network is on. It just is.
