"These don't look like just rough diagrams or Mermaid sketches. The visuals are clean and modern."
- VirtualizationHowto
"A tool that creates a network diagram on its own and keeps it up to date - I think we've all dreamed of that. [Translated]"
- IT-Connect
"It's the network scan + Docker detection combo that makes it useful, because most tools do one or the other but never both. [Translated]"
- Korben
"Built with Rust, Svelte, and TypeScript, it offers a modern alternative to stale manual diagrams like Visio files."
- Marius Hosting
"A very useful tool for corporate network administrators. The larger the network, the less effort it takes to create a diagram and the more ports can be found that are unintentionally open. [Translated]"

Up and running in three simple steps
Deploy a scanner
Install a lightweight daemon on any network. It auto-discovers hosts, services, and subnets.
Topology builds itself
As the scan runs, a full network topology generates automatically - no manual drawing.
Stays up to date on a schedule
Topology regenerates automatically. No manual re-scans, no stale docs.
Everything you need to map your network
Share, export, embed
Send live view links, export diagrams, or embed maps anywhere.
See every service at a glance
The topology shows 230+ detected services - Docker, PostgreSQL, nginx, and more - right in the visualization.
Version history
Create branches, lock versions, and compare network state over time.
Less Visio Lucidchart wrangling, more clarity
Onboard faster
New hires and new clients see the whole picture on day one - no digging through outdated wikis.
Impress your customers
Transform documentation into a live client portal with zero manual updates.
Streamline audits
Hand auditors a live network map instead of outdated spreadsheets.

Feedback from r/selfhosted and r/homelab
"It really helped me catch a couple things that were suboptimal, and be like 'why is that there', and tidy a couple things up."
u/reinhart_menken"This is sick. I just tried it out on my network and discovery's doing its thing."
u/discoshanktank"You're literally doing the thing I've dreamed of for ages."
u/blitz9826"So many features, wasn't expecting a lot more than a simple scanner and a UI."
u/Medium_Chemist_4032Flat-rate pricing. No per-device fees. Scale without surprises.
Your network diagram is minutes away
Scanopy is an automated network discovery and diagramming tool for IT teams and MSPs. A single daemon discovers hosts, maps Layer 2 and Layer 3 connections, and fingerprints 230+ services per host using SNMP, LLDP, CDP, and ARP. No per-device agents, no credentials, no manual drawing. Scans repeat on a schedule so diagrams stay current as devices come and go. Unlike monitoring platforms (Auvik, PRTG, Domotz) that bolt on mapping as a side feature, or manual tools (Visio, Lucidchart, draw.io), Scanopy is purpose-built for network documentation. Export as SVG, PNG, Mermaid, or Confluence markup, or embed maps via iframe. The Community Edition is free and open-source (AGPL-3.0). Cloud plans start at $11.99/month billed yearly with flat pricing and no per-device fees. Learn more about how automated network documentation works or read about our security practices.
