## What it is
Scanopy is a self-hostable network discovery and documentation tool that scans networks on a schedule and automatically generates live topology diagrams (L2 physical, L3 logical, workloads, and applications). Built in Rust with a Svelte UI, it replaces manually drawn network diagrams with continuously updated maps exportable as SVG, Mermaid, PNG, and Confluence.

## Use cases
- automatically generate network diagrams that stay up to date
- document my homelab network topology without drawing it manually
- discover devices, switch ports, and connections via SNMP and LLDP
- map Docker and Podman containers into network documentation
- validate network segmentation for security and compliance audits
- produce per-client network documentation as an MSP
- export network maps as SVG or Mermaid for wikis and Confluence

## When to choose
- you want living network documentation derived from actual infrastructure instead of stale Visio or draw.io files
- you run a homelab, IT team, or MSP that needs current topology maps without manual effort
- you need discovery across SNMP, LLDP, UniFi, Instant On, Docker, and Podman environments
- you want self-hosted network documentation with flat pricing and no per-device fees

## When to avoid
- you need full IT asset lifecycle management, procurement tracking, or compliance workflow tooling
- you need a bundled network monitoring and alerting platform rather than documentation
- you require a manual diagramming canvas where you place every element by hand
- you need Visio SmartShape export or deep enterprise automation runbooks
