Do I need to install a client?

No. YiLink runs in the browser—open a shared link or scan a QR code to connect.

Why is Auto Relay paid?

Relay consumes server bandwidth and infrastructure resources. Concurrent sessions significantly increase costs, so Auto Relay is offered as a paid feature.

Low-latency access to your PC in any browser

YiLink is a WebRTC-based P2P remote desktop and game streaming tool, comparable to Parsec/Moonlight. No client install—open a link or scan a QR code to start.

Download Windows Host Open Web Client

P2P by Default

Video and input travel directly between your devices—no third-party servers in the path.

End-to-end Encryption

SRTP/DTLS secures transport and protects your privacy.

Auto Relay

Automatically falls back to relay servers when direct P2P is blocked by network/NAT.

Get Started in 3 Steps

1. Install the Host

Install YiLink on your Windows host.

2. Share in One Click

Generate a shareable link or QR code.

3. Connect in Browser

Open the link in a browser on your phone/tablet/PC and start controlling instantly.

Core Features

Low-latency Control

Optimized mouse and keyboard input. For games, enable pointer lock for the best experience.

High Quality & High FPS

Stream at high resolution and refresh rate. Tune quality and smoothness based on your network.

Works on Any Device

If your browser supports WebRTC, it works. Also supports installing as a PWA app-like experience.

Share with Friends

Up to 4 clients can connect to the same host—great for watch parties, remote help, and demos.

Fast Connection

No complex network setup. Automatic NAT traversal, with adaptive relay fallback when direct P2P fails.

Browser File Transfer

No extra apps—send files peer-to-peer right in the browser.

Why Web

No client install: easier sharing, lower friction.
Links as entry points: perfect for sharing, embedding, and campaign pages.
More room to grow: next, we’ll introduce User Space for multi-host, vanity names, and richer sharing.

Turn Your PC into a Shareable Space

Upgrade from anonymous links to a recognizable, persistent, and manageable User Space. One space can include multiple hosts and entry points—share it with friends, viewers, or users, or use it as an interactive landing page.

Direct P2P is Free. Auto Relay is Priced by Cost.

YiLink prefers P2P by default. When you’re behind complex NAT or on unstable networks, Auto Relay can improve connection success rate and stability. Because relay consumes bandwidth and infrastructure, it’s offered as a paid feature.

FAQ

What is game streaming? What do I need?

Game streaming sends video from the host to your device in real time and sends your inputs back. You need a Windows PC as the host and a stable network connection.

How low can the latency be? What affects it?

Latency depends on network round-trip time (RTT) and encode/decode time. On LAN it’s often < 5ms; within the same city it’s often < 20ms.

What devices and browsers are supported? Do I need a client?

Works with major browsers like Chrome, Edge, and Safari. No client install needed.

Is my data safe? Can the server see my screen?

In direct mode, video is transmitted peer-to-peer without going through servers. In relay mode, transport is still encrypted and the server cannot decrypt the content.

Can’t connect? What is NAT?

See the Network & NAT Guide.

What is Auto Relay and why is it paid?

Auto Relay uses our servers to relay traffic and traverse complex networks. Bandwidth is expensive, so it’s a paid service.
