Nixre

Sovereign, minimalist, and ultra-fast code collaboration forge.
Official site: nixre.dev • Live Instance: git.nayhein.com

Nixre is a modern open-source Git forge UI that combines the clean, typography-driven aesthetic of Radicle and Linear with a Gitness backend (Spaces, Repositories, Pull Requests).

✨ Features

• 🎨 Minimalist Radicle-Inspired UI: Booton typography, JetBrains Mono code rendering, flat layout (decard), dark/light theme.
• 🔑 Passkeys (device convenience, not a login backend): registered passkeys can re-confirm an already active session (e.g. before a sensitive settings change). Gitness has no WebAuthn API, so a passkey alone cannot start a brand-new session — sign in with a password (or token) first.
• 🛡️ 100% Sovereign & Unbranded: Zero commercial upsell remarks, enterprise tracking, or proprietary vendor locks.
• 🔒 Registration Page Toggle (client-side only): the Admin Console can hide the sign-up page in a given browser. This is a UI convenience, not access control — the /api/v1/register endpoint is unaffected. To actually close an instance to new signups, set GITNESS_USER_SIGNUP_ENABLED=false on the backend and restart it.
• ⚡ Git Smart HTTP & SSH: Clone/push over HTTPS (/git/<space>/<repo>.git) or SSH (port 3022).
• 🔄 Pull Requests: create PRs between branches, view a unified diff per changed file, and merge with one click.
• 📁 Spaces & Organizations: Multi-tenant workspace organization for projects and teams.

Not implemented yet: Issues, CI/CD pipeline UI (Gitness itself supports CI; this UI doesn't expose it), inline PR review comments.

🌐 Self-Hosting Guide (Custom Subdomain + Sunrise Connect Box 3)

This section documents how to expose Nixre on a custom subdomain (e.g. git.yourdomain.com) behind a Sunrise Connect Box 3 (or standard ISP modem/router) with automatic Let's Encrypt SSL certificates using Caddy.

1. DNS Configuration

At your domain registrar (Namecheap, Cloudflare, GoDaddy, Porkbun):

• Add an A Record:
  • Type: A
  • Name / Host: git (for git.yourdomain.com)
  • Value: Your Public IPv4 address (find via curl ifconfig.me)
  • TTL: Automatic or 300s

2. Sunrise Connect Box 3 Port Forwarding Setup

1. Open your browser and navigate to http://192.168.1.1 (the Sunrise Connect Box 3 admin portal).
2. Log in using the settings password on the sticker under your modem.
3. In the left sidebar, navigate to Advanced settings $\rightarrow$ Security $\rightarrow$ Port forwarding.
4. Click Add rule and configure two forwarding rules for your server's local IP (e.g. 192.168.1.114):

Rule 1: HTTP / ACME SSL Validation

• Local IP: 192.168.1.114
• Local Start/End Port: 80 - 80
• External Start/End Port: 80 - 80
• Protocol: TCP (or Both)
• Enabled: On

Rule 2: HTTPS / Secure Web & Git Traffic

• Local IP: 192.168.1.114
• Local Start/End Port: 443 - 443
• External Start/End Port: 443 - 443
• Protocol: TCP (or Both)
• Enabled: On

5. Click Apply changes.

Note on Sunrise DS-Lite: If the "Port forwarding" option is missing from your Connect Box 3 dashboard, your connection is in IPv6 DS-Lite mode. Call Sunrise Support (0800 707 707) and request to "switch my Connect Box 3 to a public IPv4 Dual-Stack profile". It is free and takes ~10 minutes.

3. Caddy Reverse Proxy Configuration

In your Caddyfile:

git.yourdomain.com {
    handle /api/* {
        reverse_proxy 127.0.0.1:3001
    }
    handle /git/* {
        reverse_proxy 127.0.0.1:3001
    }
    handle {
        root * /opt/nixre/ui/dist
        try_files {path} /index.html
        file_server
    }
}

Restart Caddy (sudo systemctl restart caddy). Caddy will automatically complete the ACME HTTP-01 challenge through the Sunrise box and serve your trusted HTTPS certificate.
