NexaVPN

NexaVPN is a production-oriented, self-hosted WireGuard control plane for remote access. It combines:

• A Go backend and PostgreSQL control plane
• A React admin console
• A Tauri desktop client for Windows and macOS
• WireGuard gateway and firewall policy enforcement
• Docker Compose deployment assets

Monorepo Layout

• docs/ architecture, schema, API, and deployment design
• backend/ Go API, migrations, seeds, and domain services
• admin-web/ React + Vite admin UI
• desktop-client/ Tauri desktop client
• deploy/ Docker Compose, reverse proxy, and gateway assets

Phase Status

This repository contains the initial production-minded MVP scaffold:

• Phase 1: architecture, schema, API, enrollment, provisioning, gateway design
• Phase 2: backend scaffold, migrations, auth, CRUD, audit, profile generation
• Phase 3: admin UI scaffold and core pages
• Phase 4: desktop client scaffold, enrollment flow, profile provisioning abstraction
• Phase 5: deployment assets, bootstrap scripts, and hardening notes

Quick Start

1. Copy deploy/.env.example to deploy/.env.
2. Review docs/architecture.md and docs/deployment.md.
3. Start the stack with Docker Compose from deploy/.
4. Open http://localhost.
5. On the admin login screen, choose the bootstrap flow if this is a fresh install.
6. Create the initial admin, then sign in.

Important MVP Notes

• WireGuard remains the tunnel transport. NexaVPN is the control plane around it.
• Client private keys are generated on-device and are not stored server-side.
• Gateway-side enforcement uses nftables generated from issued policy state.
• The desktop client is structured so NexaVPN is the only user-facing VPN app.
• The tunnel layer still uses WireGuard internally, but the intended delivery model is a NexaVPN-bundled tunnel backend, not a separately used WireGuard app.

Desktop Requirements

• Windows x86: package NexaVPN with the bundled Windows x86 tunnel helper
• macOS ARM: package NexaVPN with the bundled macOS ARM tunnel helper

See client-platforms.md for the current platform strategy.

Helper build commands:

cd desktop-client
npm run helper:windows-x86
npm run helper:macos-arm64

Gateway utility scripts:

./deploy/scripts/generate-gateway-keypair.sh
./deploy/scripts/get-admin-token.sh http://localhost admin your-password

Local Test Flow

cd deploy
cp .env.example .env
docker compose up --build

Then:

1. Visit http://localhost
2. Bootstrap the first admin account
3. Create a standard user in the Users page
4. Create a user policy in the Policies page
5. Enroll a device from the NexaVPN desktop app against http://localhost
6. Inspect the generated device profile in the Devices page

Realistic MVP Usage

The current repository can act as a real WireGuard control plane and issue per-device peer state, but these platform pieces are still at MVP level:

• the desktop app now targets an embedded NexaVPN tunnel backend model, and the helper source is in-repo, but final platform builds and signing still need to happen per target OS
• the gateway helper now applies WireGuard and nftables state in-container, but you still need to provide the gateway private key and correct uplink interface settings
• admin debug profiles intentionally use a private-key placeholder because the client private key stays local
