portracker

A self-hosted, real-time port monitoring and discovery tool.

By auto-discovering services on your systems, portracker provides a live, accurate map of your network. It helps eliminate manual tracking in spreadsheets and prevents deployment failures caused by port conflicts.

Key features:

• Automatic Port Discovery: Scans the host system to find and display running services and their ports automatically. No manual data entry is needed.
• Platform-Specific Collectors: Includes specialized collectors for Docker and TrueNAS to gather rich, contextual information from the host.
• Lightweight & Self-Contained: Runs as a single process with an embedded SQLite database. No external database dependencies like PostgreSQL or Redis are required.
• Peer-to-Peer Monitoring: Add other portracker instances as peers to view all your servers, containers, and VMs from a single dashboard.
• Hierarchical Grouping: Organize servers in a parent-child structure, perfect for nesting servers, e.g. a VM's portracker instance under its physical host.
• Enhanced TrueNAS Discovery: Providing an optional TrueNAS API key allows portracker to discover running VMs* and gather enhanced system information like the OS version and uptime.
• Modern & Responsive UI: A clean dashboard with light/dark modes, live filtering, and multiple data layout views (list, grid, table).
