Frequently Asked Questions
Quick answers to common questions. Contact us if you need more detail.
What is Unravlr?
Unravlr is a tool that converts structured Excel input into deterministic draw.io network diagrams. Define your network topology once in a workbook, then generate consistent, professional diagrams without manual layout work.
What output format does it produce?
Unravlr generates .drawio files that open directly in draw.io or diagrams.net. The output includes device nodes, port labels, port channels, media type indicators, and tier-based auto-layout.
Who is it for?
Network engineers, architects, and NOC teams who need to produce repeatable, standardized network diagrams. Particularly useful for teams managing multi-vendor, multi-tier topologies.
How deterministic is the layout?
Given the same input workbook, Unravlr produces the same output every time. Layout is computed from tier structure and port definitions — not from any heuristic that could vary between runs.
Does it work in secure or air-gapped environments?
The frontend is a static export that can be hosted anywhere. The generation backend runs in a Cloudflare Worker. For enterprise deployments, self-hosted Worker options are available — contact us to discuss.
Is there a size limit on topologies?
The evaluation tier supports up to 20 devices per topology. Pro and Enterprise tiers support larger topologies with more devices per tier.
What happens to my data?
Excel files are processed ephemerally in the Worker — no persistent storage. Generated diagrams are returned directly to your browser. See our privacy policy for full details.
