Nginx Proxy Manager is a web-based administrative interface for configuring and managing Nginx reverse proxy hosts and server rules within Docker containers. It functions as a containerized network gateway that routes external web traffic to internal services and backend applications.
The system automates the acquisition and renewal of Let's Encrypt SSL certificates to encrypt network traffic without manual command line intervention. It provides a graphical dashboard for defining proxy hosts, access lists, and custom server configurations, removing the need for manual configuration file editing.
Capability areas include proxy host administration and reverse proxy routing, alongside security features such as host access restriction, password protection, and IP-based access lists. The tool also includes administrative user management with audit logs for system changes.
