Comparison Table
EdrawMax
SMBMulti-platform diagramming software with dedicated network diagram templates and thousands of vendor equipment symbols.
Visio stencil compatibility for importing device shapes and keeping icon semantics consistent across diagram projects.
EdrawMax is a diagramming tool built around stencils, so network device icons and connection styles can be reused across logical network diagrams and physical network diagrams. The workspace supports automatic layout algorithms for aligning nodes and routing links, which reduces manual spacing for subnet and dependency views. It also supports Visio stencil compatibility and export to common image formats, which helps when network diagrams must match existing documentation conventions.
A key tradeoff is that EdrawMax does not provide native network topology auto-discovery workflows like LLDP neighbor discovery or SNMP polling for inventory synchronization. EdrawMax fits best for teams that already have topology information and need repeatable diagram templates, fast edits, and consistent export to drive network documentation automation.
- +Stencil-driven device libraries support consistent network icon usage
- +Automatic layout reduces spacing work for larger topology diagrams
- +Exports to PDF, PNG, and SVG support documentation and reviews
- +Visio stencil compatibility helps reuse existing diagram assets
- –No native SNMP polling or LLDP neighbor discovery for inventory sync
- –Network change tracking depends on manual diagram updates
- –Automation and API surface are limited for topology ingestion
- –Hybrid or cloud topology mapping still requires manual structuring

Network change tracking ties topology revisions to observed discovery changes so diagram drift can be reviewed over time.
Domotz maps wired and wireless networks into visual topology views by combining device reachability and discovery signals into a diagram-style network inventory. It focuses on automated documentation workflows such as network change tracking, topology views, and configuration backup references that keep diagrams aligned with the live environment.
Domotz also supports integration-oriented reporting and exports that help teams publish network documentation outputs for audits and operational handoffs. Network diagrams are treated as an outcome of monitoring and discovery rather than a drawing-only artifact.
- +Automates topology updates from discovery and monitoring signals instead of manual redrawing
- +Supports network change tracking to highlight topology drift over time
- +Exports documentation outputs for operational sharing and recordkeeping
- +Provides multi-vendor device coverage in a single topology view
- –Diagram editing is secondary to discovery, so layout control can feel limited
- –LLDP and SNMP coverage depends on network configuration and switch settings
- –Complex logical diagram grouping takes more operational discipline to stay consistent
- –Visio-style stencil workflows are constrained compared with dedicated diagram tools

- +Strong stencil and template workflow for consistent network documentation
- +Reliable exports to PDF, PNG, and SVG for downstream publishing
- +Repeatable diagram construction via VBA macros for recurring layouts
- +Better Microsoft file interoperability than many diagram tools
- –No built-in topology auto-discovery for network devices

How to Choose the Right Network Diagramming Software
We separate options by how they handle discovery and diagram fidelity, how much editing control you get after data import, and how well they keep diagrams consistent over time with updates. Focus on automation depth in network diagrams, not just visual styling—especially for integration and data handling.
Discovery data import sources
Why it matters
Discovery data import sources determine whether diagrams start from your real network details or from manual entry. When this is weak, you spend more time fixing gaps than documenting changes.
How to check
Ask for a sample workflow that imports device/connection data into a diagram. In the demo, bring a small exported dataset (or connect to a source if supported) and confirm what appears: nodes, links, and ports.
Auto layout with edit control
Why it matters
Auto layout with edit control matters because network diagrams need both readability and precision. If layout fights your edits, ongoing documentation becomes slow and inconsistent.
How to check
Create or import a diagram, then manually move a few nodes and labels. Re-run layout or refresh and verify whether your custom positions and labels stay, or whether the tool reorders everything.
Physical vs logical diagram modeling
Why it matters
Physical vs logical diagram modeling affects how accurately the tool represents what you’re documenting. If the model can’t switch views cleanly, teams end up maintaining multiple versions manually.
How to check
In the demo, build one diagram that uses device-to-device relationships and another that focuses on different grouping logic. Check whether the same underlying elements can be viewed differently without breaking links and annotations.
Update behavior on refresh
Why it matters
Update behavior on refresh tells you whether new data merges cleanly or overwrites your work. For network documentation, this determines how painful it is to keep diagrams current.
How to check
Make edits (rename a label, add a note, drag one node) then run a refresh from the same dataset with one change. Confirm what is preserved, what is overwritten, and whether the tool highlights differences.
Export formats and fidelity
Why it matters
Export formats and fidelity decide whether your diagrams survive handoff to other documentation workflows. Poor fidelity leads to unreadable images or missing labels and legends.
How to check
Export the same diagram to the formats offered and open the outputs. Verify that link labels, device names, grouping, and styling (colors/line types) remain readable and consistent.
Roles, permissions, audit trails
Why it matters
Roles, permissions, audit trails matter when multiple people edit diagrams tied to operational knowledge. Without them, it’s hard to track what changed and who caused it.
How to check
Ask how the tool supports at least two roles (viewer vs editor). Then check whether it keeps an audit trail of edits like label changes, node moves, and import refreshes.
Red flags
- Refresh overwrites your manual edits without preserving positions or labels
- Export drops legends or link labels, making diagrams harder to read
- Permissions are limited to single-user or lacks any audit trail of changes
Fit by situation
- If we rely on imported network data and need diagrams to start accurately, prioritize discovery data import sources.
- If we frequently rearrange diagrams for clarity between updates, prioritize auto layout with edit control.
- If we must keep diagrams current without losing annotations, prioritize update behavior on refresh.
