Comparison Table
SmartDraw
SMBDiagramming software with network design templates, device libraries, and automated formatting.
SmartDraw’s template and style constraints generate uniform network diagram structure without custom layout rules.
SmartDraw is a network diagram drawing tool built around structured diagram templates and strong export paths for common office formats. It supports drag-and-drop network symbols, orthogonal connector behavior, and diagram layouts that keep large topologies readable.
SmartDraw also integrates with Microsoft Office workflows through diagram export and supports file exchange workflows used in documentation pipelines. For network planning artifacts, it works best as a manual topology drawing and layout environment rather than an auto-discovery or live sync system.
- +Template-driven diagram creation keeps complex network drawings consistent
- +Orthogonal routing and auto-alignment reduce connector chaos in dense layouts
- +Strong export compatibility for documentation workflows
- +Large stencil and icon libraries for standard network symbols
- –No built-in network auto-discovery or LLDP or SNMP polling
- –Live topology sync and diagram updates from telemetry are not a native workflow
- –Limited support for infrastructure-as-code graph ingestion workflows
- –Extensibility depends on external assets rather than an API-first model

Best for: Fits when teams need consistent, template-based network diagrams for documentation and reviews.
Gliffy
SMBBrowser-based diagramming tool with network shapes and integrations for Confluence and Jira.
Embedded Confluence and Jira diagrams retain page and issue context, comments, and workspace-controlled access.
Gliffy combines a drag-and-drop editor with shape libraries for routers, switches, servers, cloud services, and office layouts. Templates, layers, hyperlinks, comments, and revision controls support architecture reviews and infrastructure documentation. PNG, SVG, and PDF exports make diagrams usable in runbooks, presentations, and handoff documents.
The Atlassian connection reduces context switching for teams that manage infrastructure work in Confluence and Jira. Gliffy does not provide native device discovery, live telemetry ingestion, or broad automation for generating diagrams from network data. An IT team planning a migration in Confluence gets strong documentation workflow coverage, but a network operations center needs separate monitoring and mapping tools.
- +Native Confluence and Jira embedding keeps diagrams beside requirements and incidents.
- +Shape libraries cover routers, switches, servers, cloud services, and office layouts.
- +Layers, connectors, hyperlinks, and reusable templates support structured diagram editing.
- +PNG, SVG, and PDF exports support operational documentation and presentations.
- –No native device discovery from live network telemetry.
- –Automation and public API coverage are narrower than Lucidchart's integration model.
- –Complex diagrams can require manual connector placement and layout adjustment.
- –Atlassian-centered workflows provide less flexibility for teams outside Confluence and Jira.

Miro also integrates with external data sources and workflows through its automation features and API surface, which helps keep diagrams aligned with changing environments. It is less specialized for device-level network discovery and protocol-driven topology building than dedicated network topology mapper tools.
- +Infinite canvas and grouping keep large topology maps navigable
- +Linking shapes and connectors supports logical flow diagrams and overlays
- +Automation via templates and workflows reduces repeated manual diagram steps
- +Integrations and API enable programmatic diagram updates
- –No built-in auto-discovery via SNMP polling or LLDP neighbor discovery
- –Orthogonal routing and hierarchical topology layout are limited versus diagram specialists
- –Network data imports like route tables and BGP peer mapping require manual modeling

How to Choose the Right Network Diagram Drawing Software
We see big differences in how network diagram drawing software handles import/export, layout behavior, and how accurately it preserves relationships. Pick based on the labels that affect day-to-day edits: file interoperability, routing and connections, and collaboration workflow.
Diagram import and export formats
Why it matters
Diagram import and export formats determine whether you can move drawings between teams and tools without redrawing everything. When exports are reliable, you also keep change history outside the editor.
How to check
Ask to import a sample diagram from the most common format you use today, then verify node positions and link endpoints. Export to at least two common targets and check whether labels, grouping, and connections survive.
Connection routing stays attached
Why it matters
Connection routing stays attached prevents diagrams from breaking when you rearrange devices or sites. For network diagram drawing, link correctness matters more than visual neatness.
How to check
In a demo, drag a node after connections are created and confirm the link endpoints track the node, not the old coordinates. Turn on any auto routing, then manually move several nodes to see if links stay consistent.
Layout controls for readability
Why it matters
Layout controls for readability let us maintain clarity as diagrams grow and change. Good controls keep diagrams comparable across revisions.
How to check
Create a small topology, then run each available layout option and inspect label overlap and link crossings. Ask whether you can lock positions for specific groups before running layout again.
Data-driven device and link editing
Why it matters
Data-driven device and link editing reduces hand-maintenance when you update names, ports, or attributes. It also supports repeatable updates across multiple diagrams.
How to check
Check whether you can edit devices and links through a table/panel and see updates reflected on the canvas. Test by changing a device name and confirm every connected label updates as expected.
Collaboration and version history
Why it matters
Collaboration and version history help us review changes without losing context. It matters when multiple analysts edit diagrams or when you need auditability of edits.
How to check
Create edits as two users (or two sessions) and verify conflict behavior and who-wrote-what history. Export or view prior revisions to confirm changes are distinguishable.
API and automation for diagram updates
Why it matters
API and automation for diagram updates lets us keep diagrams aligned with external sources and repeat workflows. When integration depth is real, we can standardize diagram production.
How to check
Ask what endpoints or scripting hooks exist to read/write diagrams, and whether they support diagram elements and relationships. During the demo, propose a small batch update (rename a set, move a group) and watch for repeatable results.
Red flags
- Exports break labels or detach links after re-import
- Dragging nodes causes connections to drift or reroute unpredictably
- Collaboration history is missing or hard to reconcile between revisions
Fit by situation
- If you regularly reuse diagrams across tools, prioritize Diagram import and export formats.
- If you expect frequent edits to topology layout, prioritize Connection routing stays attached.
- If you need repeatable updates across many diagrams, prioritize API and automation for diagram updates.
