portracker

portracker is a self-hosted, real-time port monitoring and discovery tool that automatically maps running services across systems and containers to eliminate manual tracking and prevent port conflicts. The platform scans host environments to detect active services and their associated ports without requiring manual data entry, producing a live and accurate network view. It includes specialized collectors for platforms such as Docker and TrueNAS to provide deeper contextual insights into containerized and virtualized workloads. The application distinguishes between internal container ports and externally published host ports, giving operators complete visibility into service exposure. Designed to be lightweight, portracker runs as a single process using an embedded SQLite database, avoiding the need for external infrastructure. Overall, it helps DevOps teams maintain reliable deployments by providing continuous, automated port intelligence.
