No spreadsheet has to track which service owns which port, because portracker discovers every service and port on your servers and keeps the list current from a self-hosted dashboard. Begin with a single port, shown with its owning service, its source (Docker or the host system), and its address, with internal container ports told apart from ports published to the host. Step back and ports gather into services: expandable cards carrying an icon, a health dot, and a port count, in list, grid, or table layouts, where a Why this status popover names the failing component and the rule that fired. Step back again and each server gets its own panel with hostname, OS, CPU, memory, and uptime, plus TrueNAS apps, VMs, and LXC containers once an API key is added. Step back once more and the whole fleet appears, because other portracker instances can be linked as peers, a VM's instance can be nested under its host, and every server can be searched at once. Along the way, rename services, hide the noisy ones, attach notes, act on a selection in bulk, or press Generate port for an unused number before deploying something new. Optional sign-in with a first-run setup wizard, an autoxpose link that shows public URLs and SSL status, light and dark themes, and keyboard shortcuts finish the picture.

Every cable, switch port, VLAN, and rack unit in a homelab or small server room gets a documented place in Rackpad, a self-hosted inventory and operations workspace. Rack elevations show mounted gear, including paired half-width appliances. Switch-panel port maps and aggregate ports show what is patched where. Cables carry type, length, and color, editable in bulk. VLANs, subnets, DHCP scopes, reservations, and zones sit in one Networks workspace, with gateway and DNS protection and a mismatch review for IP assignments. Storage topology follows drives, bays, and pools that span several devices. Wi-Fi controllers, access points, hypervisor hosts, and virtual machines have pages of their own, and Proxmox and Hyper-V hosts can be imported after review. Discovery scans a subnet or any CIDR and stages every finding in an inbox. Per-device checks over ICMP, TCP, HTTP, HTTPS, and SNMP raise alerts by email, Discord, or Telegram. Everything feeds a movable topology map. Markdown runbooks attach to devices, and an audit log records every change. Admin, editor, and viewer roles control access, and OpenID Connect login is optional.

Mapping every physical server, virtual machine, container, and network link across a sprawling homelab into a live interactive canvas, Circuit Breaker gives infrastructure operators real-time topology visualization, IP address management, and rack elevation modeling on a single screen. Operators can switch between hierarchical, concentric, cortex ring, radial, and force-directed graph layouts where animated edges reflect link speeds and color-coded status rings display live hardware health. Automated discovery scans local subnets using nmap, SNMP, and ARP while querying Proxmox VE clusters, TrueNAS storage pools, and UniFi controllers, staging newly detected nodes in a review queue before adding them to the map. For multi-site labs or isolated VLANs, lightweight remote agents connect outbound over Noise-encrypted links after fingerprint approval to report host telemetry and run scoped network scans without opening inbound firewall ports. Rack diagrams let administrators drag servers into U slots with cabling overlays using a built-in catalog covering Dell, HPE, Supermicro, Ubiquiti, MikroTik, Synology, and APC gear alongside live iDRAC, iLO, and UPS metrics. Role-based access control, OIDC single sign-on, TOTP multi-factor authentication, encrypted full-state snapshots, and a SHA-256 hash-chained audit log keep multi-user operations accountable.
