meridian-vpn 3.1.0

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).

Install

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

curl -sSf https://meridian.msu.rocks/install.sh | bash

Or install directly from PyPI:

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

Quick start

meridian setup                       # interactive wizard
meridian setup 1.2.3.4               # deploy to server
meridian setup 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 an HTML page with QR codes and one-tap deep links. In domain mode, the page is also hosted on the server with live usage stats.

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.

What you need

• A VPS (Debian/Ubuntu) with root SSH key access — $3–5/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)

Commands

Command	Description
meridian setup [IP]	Deploy proxy server (interactive wizard if no IP)
meridian setup IP --xhttp	Deploy with XHTTP transport (enhanced stealth)
meridian client add NAME	Add a named client key
meridian client list	List all clients
meridian client remove NAME	Remove a client key
meridian server list	List managed servers
meridian check [IP]	Pre-flight validation (ports, SNI, ASN, DNS)
meridian scan [IP]	Find optimal SNI targets on server's network
meridian ping [IP]	Test proxy reachability from this device
meridian diagnostics [IP]	Collect info for bug reports
meridian uninstall [IP]	Remove proxy from server
meridian self-update	Update CLI

Architecture

Standalone mode — Xray on port 443. No domain needed.

Domain mode — HAProxy routes by SNI: Reality traffic goes to Xray, everything else to Caddy (auto-TLS). Adds VLESS+WSS through Cloudflare CDN as a fallback.

Client apps

After setup, connect with any of these apps:

Platform	App
iOS	v2RayTun
Android	v2rayNG
Windows	v2rayN
All platforms	Hiddify

Common scenarios

My IP got blocked — The most common scenario in censored regions. Get a new VPS, run meridian setup 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 setup. 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 an HTML file. Send it by email, iMessage, or AirDrop. They open it on their phone, install the app (one tap), scan the QR code, and connect. In domain mode, the page is also hosted at a URL (https://yourdomain/connection) you can share as a link — 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 setup YOUR_SERVER_IP.

Troubleshooting

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