# Outline VPN — Secure Access Server by Jigsaw (Google)

> An open-source VPN solution designed to make it easy to create and share secure internet access. Built by Jigsaw (a Google subsidiary), Outline uses the Shadowsocks protocol and provides both a server manager app and cross-platform client apps.

## Install

Save as a script file and run:

# Outline VPN — Secure Access Server by Jigsaw (Google)

## Quick Use
```bash
# Install on any Linux server with a single command
sudo bash -c "$(wget -qO- https://raw.githubusercontent.com/Jigsaw-Code/outline-server/master/src/server_manager/install_scripts/install_server.sh)"
# Then open the Outline Manager app and paste the displayed access key
```

## Introduction
Outline is an open-source VPN platform created by Jigsaw, a subsidiary of Google focused on internet freedom. It makes deploying a personal VPN server as simple as running a single install script, then sharing access keys with users via the Outline Manager desktop app.

## What Outline Does
- Deploys a Shadowsocks-based proxy server on any Linux machine or cloud provider with one command
- Provides a desktop Manager app to create, revoke, and monitor access keys without touching the command line
- Offers native client apps for Windows, macOS, Linux, iOS, and Android
- Encrypts traffic using AEAD ciphers making it resistant to deep packet inspection and blocking
- Supports per-key data transfer limits and usage monitoring through the Manager interface

## Architecture Overview
The Outline Server runs inside a Docker container, exposing a Shadowsocks proxy endpoint and an HTTPS management API. The Manager app communicates with this API to provision and revoke access keys. Each key maps to a unique port and cipher configuration on the server. Client apps connect using the standard Shadowsocks protocol, tunneling all device traffic through the encrypted proxy.

## Self-Hosting & Configuration
- Run the install script on any Linux VPS (DigitalOcean, AWS Lightsail, Linode, or bare metal)
- Open the Outline Manager app on your desktop and paste the server API URL generated during install
- Create access keys in the Manager and share them as `ss://` links or QR codes
- Set per-key data limits to manage bandwidth across multiple users
- Update the server by re-running the install script, which pulls the latest Docker image

## Key Features
- One-command server deployment with automatic Docker container setup and TLS configuration
- Shadowsocks protocol resists censorship and deep packet inspection better than standard VPN protocols
- Per-user access keys with individual data caps and usage tracking
- Cross-platform client apps with a consistent, simple interface on all major operating systems
- No user accounts or centralized authentication required, just share an access key

## Comparison with Similar Tools
- **WireGuard** — faster kernel-level protocol; Outline prioritizes censorship resistance via Shadowsocks
- **OpenVPN** — widely supported but complex to configure; Outline automates all server setup
- **Tailscale/Headscale** — mesh networking focus; Outline is designed for simple proxy access to the open internet
- **Algo VPN** — similar ease of deployment using WireGuard/IPSec; Outline adds a graphical Manager app and Shadowsocks for anti-censorship
- **Streisand** — multi-protocol server setup (archived); Outline focuses on a single well-maintained Shadowsocks stack

## FAQ
**Q: Is Outline a full VPN or a proxy?**
A: Outline uses Shadowsocks, which is a SOCKS5 proxy. The client apps route all device traffic through it, providing VPN-like functionality with proxy-level censorship resistance.

**Q: Which cloud providers are supported?**
A: The install script works on any Linux server. The Manager app has one-click setup for DigitalOcean, and manual setup works on AWS, GCP, Linode, Vultr, or any other provider.

**Q: Can I share access with others?**
A: Yes. Create multiple access keys in the Manager app and share them as links or QR codes. Each key can have its own data limit.

**Q: Is it safe to use in countries with internet censorship?**
A: Outline was designed with censorship resistance in mind. Shadowsocks traffic is difficult to distinguish from normal HTTPS traffic, making it harder to block than traditional VPN protocols.
