What Infra Stack does

Objects and connections

Create, connect and label objects. Every connection can carry its own label.

Show and hide layers

Hide layers with one click. Connections through hidden objects can be passed through so dependencies stay visible.

Tags and filters

Tag objects and filter by any or all tags. Non-matches are dimmed or hidden.

Import and export

Import draw.io and diagrams.net files and export them again, layers included. Plus PNG, JSON and a PDF report with object lists.

Stored locally

Diagrams stay in your browser’s storage. There is no account and no server that sees your data.

Light, dark, four languages

German, English, French and Spanish, with light and dark appearance.

Who is Infra Stack for?

Homelab

Keep track of servers, VMs, containers and network, and still know what depends on what after the next rebuild.

Administration

Explain dependencies between hardware, services and applications, e.g. for maintenance windows or disaster recovery plans. Please get in touch for business use.

Training and study

Understand and present the layer model of an IT landscape with real examples.

A lean alternative to Visio and draw.io

Visio and draw.io are general-purpose tools for any kind of diagram. Infra Stack focuses on IT infrastructure: the layer model is built in, objects can be tagged and filtered, and every layer can be viewed on its own. You can import existing draw.io diagrams and export back to draw.io at any time.

Infra Stack FAQ

Is Infra Stack free?

Yes, for private and non-commercial use. Business use requires an arrangement.

Where are my diagrams stored?

In your browser’s local storage. To back up or move to another device, export the diagram as a JSON file.

Can I bring my draw.io diagrams?

Yes. Infra Stack reads .drawio and .xml files from draw.io or diagrams.net and exports to that format as well.

Does Infra Stack replace a CMDB like i-doit?

No. Infra Stack is a visualisation tool. For inventory, licences and contracts a CMDB such as i-doit remains the right tool; Infra Stack shows how things connect.
