Introduction
Nginx UI provides a browser-based dashboard for managing Nginx server configurations. It replaces manual file editing with a visual interface that includes syntax highlighting, auto-completion, and built-in certificate management.
What Nginx UI Does
- Provides a visual editor for Nginx configuration files with syntax highlighting
- Automates SSL certificate issuance and renewal via Let's Encrypt
- Shows real-time access and error log streaming in the browser
- Monitors server performance including CPU, memory, disk, and network usage
- Manages multiple Nginx instances from a single dashboard
Architecture Overview
Nginx UI is a single Go binary that serves a Vue 3 frontend. It reads and writes Nginx config files directly on the host filesystem and communicates with the Nginx process for reloads and testing. Certificate management uses the ACME protocol. The application stores its own settings in an SQLite database.
Self-Hosting & Configuration
- Install via the provided shell script, Docker image, or manual binary download
- Default web port is 9000; configurable via the settings file
- Requires read/write access to the Nginx config directory (typically /etc/nginx)
- TLS for the UI itself can be configured in the application settings
- Supports two-factor authentication for admin access
Key Features
- Code editor with Nginx directive auto-completion and validation
