Scanopy is a network discovery and documentation platform that scans your environment to identify hosts, services, and how they connect. It generates interactive topology diagrams that stay up to date through scheduled and distributed discovery.

Key Features

  • Automatic discovery of hosts, subnets, and service relationships
  • Interactive topology visualization with customization for clear network diagrams
  • 200+ built-in service definitions to identify common infrastructure and applications
  • Distributed scanning using deployable daemons across network segments and VLANs
  • Docker-aware discovery to map containerized services
  • Multi-user organization management with role-based permissions
  • Change tracking and versioning to compare network state over time
  • Export and sharing options for diagrams and live views

Use Cases

  • Homelab and multi-VLAN network documentation without manual diagram maintenance
  • IT and DevOps inventory and dependency mapping across servers and container stacks
  • Audit, compliance, and exposure reviews by visualizing reachable services and misconfigurations

Limitations and Considerations

  • Some features and collaboration workflows may be oriented toward organizational use (multi-user, roles), which can add complexity for very small setups

Scanopy is well-suited for teams and individuals who want continuously updated network diagrams and documentation generated from real discovery data. It reduces ongoing documentation effort while improving visibility into network topology and exposed services.

PortNote

PortNote

Self-hosted port inventory to document which services use which ports across servers and VMs, helping prevent conflicts and keep infrastructure organized.

PortNote is a self-hosted web application for tracking and documenting which network ports are in use across your servers and virtual machines. It centralizes port assignments and related notes so you can avoid conflicts and keep a clear overview of your infrastructure.

Key Features

  • Web UI to add servers/VMs and record port usage per system
  • Central dashboard view of your port landscape
  • Create and document port assignments to prevent collisions
  • Random port generator to help pick unused ports
  • Authentication via configurable login credentials

Use Cases

  • Maintain an internal registry of ports used by homelab or production services
  • Plan migrations and deployments without accidentally reusing ports
  • Audit and document service exposure and port allocations across hosts

Limitations and Considerations

  • Requires a PostgreSQL database backend
  • Designed for manual documentation rather than automatic network scanning

PortNote helps replace spreadsheets with a structured, searchable inventory of port assignments. It is a practical tool for teams and individuals who want clearer operational visibility and fewer port-related surprises.
