tom_doerr · x · 2026-09-21
Portracker is a self-hosted, real-time port monitoring and discovery tool with 2.4k GitHub stars. It scans host systems to automatically find running services and their ports — no manual data entry — replacing spreadsheet tracking and preventing deployment failures from port conflicts. It ships platform-specific collectors for Docker and TrueNAS, and distinguishes internal container ports from published ones.
