Unchain Proxy Server

Unchain is a lightweight and easy-to-use proxy server designed to bypass network restrictions, censorship, and surveillance effectively.

Key Features

• Protocol Support : Seamlessly handles TCP and UDP (VLESS) packets over WebSocket with TLS/Cloudflare support.

• Build Your Own VPN Business : Provides a robust platform for starting your own VPN services.

• Compatibility : Fully compatible with popular proxy clients like v2rayN or any application supporting the VLESS + WebSocket protocol.

How It Works

Unchain operates as a proxy/VPN server, compatible with popular proxy clients such as v2rayN or any application that supports the VLESS+WebSocket protocol.

It accepts traffic from various client applications, including:

• v2rayN
• v2rayA
• Clash
• v2rayNG
• iOS app Shadowrocket

Unchain processes incoming traffic and securely forwards it to the destination server, ensuring both security and efficiency in communication.

Unchain Architecture

Unchain is a dead simple VLESS over websocket proxy server. The core biz logic is only 200 lines of code.

app_ws_vless.go.

Unchain server uses a simple architecture that is VLESS over WebSocket (WS) + TLS.

Usage

1. Build from Source

To build from source, follow these steps:

1. Clone the repository and navigate to the cmd/node directory:

cd cmd/node

1. Copy the example configuration file and customize it:

cp config.example.standalone.toml config.toml

1. Run the application:

go run main.go

2. Deploying on Your Own Ubuntu Server Using GitHub Actions

You can deploy the application on an Ubuntu server using GitHub Actions.

Here's how:

1. Fork the repository to your GitHub account. 2.

Create an Environment named production in your repository settings. 3.

Add the following SSH connection details to the Environment Secrets:

• EC2_HOST: The SSH host with port (e.g., 1.1.1.1:20).
• EC2_USER: The SSH user (e.g., ubuntu).
• EC2_KEY: Your SSH private key.

1. Add your TOML configuration file content to the Environment Variables:

• CONFIG_TOML: Copy the content of your config.toml file, replace all ** with ', and paste it here.

3. Running the Application

Once the application is running, you will see a VLESS connection schema URL in the standard output.

Copy and paste this URL into your V2rayN client.

Congratulations! You now have your self-hosted proxy server up and running.

4. (Optional) create your own admin app for Auth and Data-traffic

create an RESTful API for chain proxy server push :Register API example code
