meridian-vpn 3.8.3

Censorship-resistant VLESS+Reality proxy server management

Meridian

Deploy a censorship-resistant proxy server in one command.
Invisible to DPI, active probing, and TLS fingerprinting.

What is this

Meridian deploys a private, undetectable VPN server in minutes. Share secure internet access with family and friends — they scan a QR code and connect. When your IP gets blocked, spin up a new server and be back online in minutes. No technical knowledge required on the client side.

Whether you're the "tech friend" setting up VPN for people you care about, a power user managing multiple servers, or an NGO providing access in a censored region — Meridian handles the complexity so you can focus on staying connected.

See SECURITY.md for the threat model and what Meridian protects against (and what it doesn't).

Why Meridian?

	Meridian	Raw 3x-ui	Marzban	Hiddify Manager
Install	One command	Manual Docker + config	Docker + CLI	Script + web UI
Client handoff	QR + hosted page	Manual URL sharing	Panel-only	Panel-only
Architecture	HAProxy+Caddy+Xray (hardened)	Xray only	Xray+Nginx	Xray+Nginx
Relay support	Built-in L4 relay	Manual	No	Manual
Rebuild workflow	deploy NEW_IP	Start over	Reconfigure	Reconfigure

Meridian is an orchestrator — it configures Docker, Xray, HAProxy, Caddy, firewall, BBR, and TLS certificates automatically. You focus on deploying and sharing access, not debugging configs.

Install

Works on macOS and Linux. Windows users: use WSL.

curl -sSf https://getmeridian.org/install.sh | bash

Or install directly from PyPI:

uv tool install meridian-vpn    # recommended
pipx install meridian-vpn       # alternative

Quick start

meridian deploy                       # interactive wizard
meridian deploy 1.2.3.4               # deploy to server
meridian deploy local                 # deploy on this server (no SSH needed)
meridian deploy 1.2.3.4 --domain d.io # with CDN fallback

After setup, your server is a fully functional proxy. Share access:

meridian client add alice            # generate keys for a friend
meridian client list                 # see all clients
meridian client remove alice         # revoke access

Each client gets a connection page hosted on the server with QR codes, one-tap deep links, and live usage stats. Share the URL directly — no file transfer needed.

How it works

Meridian deploys VLESS+Reality — a protocol that makes your server indistinguishable from a legitimate website:

Censorship method	How Meridian beats it
Deep Packet Inspection	Traffic is byte-for-byte identical to normal HTTPS. No proxy signatures.
Active probing	Censors connecting to your server get a real TLS certificate from microsoft.com. Only clients with your private key reach the proxy.
TLS fingerprinting	uTLS impersonates Chrome's exact Client Hello, matching billions of real devices.
IP blocking	Domain mode routes through Cloudflare CDN as a fallback — no direct IP exposure.

Architecture

Standalone mode — HAProxy on port 443 routes Reality traffic to Xray. Caddy provides auto-TLS (Let's Encrypt IP certificate) for hosted connection pages, panel access, and XHTTP transport. No domain needed.

Domain mode — Same architecture, plus Caddy handles VLESS+WSS through Cloudflare CDN as a fallback when the server IP is blocked.

Relay mode — A lightweight TCP forwarder (Realm) on a domestic server forwards port 443 to the exit server abroad. All protocols work through the relay with end-to-end encryption.

What you need

• A VPS (Debian/Ubuntu) with root SSH key access — $5/month from any provider
• Recommended: Finland, Netherlands, Sweden, Germany (low latency, not flagged)
• Optional: a domain pointed to the server (for CDN fallback via Cloudflare)

Common scenarios

My IP got blocked — The most common scenario in censored regions. Get a new VPS, run meridian deploy NEW_IP, then re-add clients with meridian client add. If you're in domain mode, update the DNS A record to point at the new IP and re-run deploy. If you're not using domain mode yet, consider switching (--domain) to get a CDN fallback through Cloudflare — when the IP is blocked, the WSS/CDN link still works.

Sharing with family — After meridian client add alice, you get a shareable URL hosted on the server. Send the link by email, iMessage, or any messenger. They open it on their phone, install the app (one tap), scan the QR code, and connect. No file transfer needed.

First-time VPS setup — Rent a VPS from any provider (DigitalOcean, Hetzner, Vultr — $4–6/month). Choose Debian 12 or Ubuntu 22.04+. Make sure you have SSH key access (not just password). Then run meridian deploy YOUR_SERVER_IP.

Troubleshooting

Not connecting? Run meridian test to check if the server is reachable, or use the web-based ping tool.
