If you’re leaving Gliffy for automatic network mapping, don’t assume another general diagramming app will discover your network: the published material does not confirm that any pick here does. For a low-cost diagramming alternative, draw.io has a free plan and flexible storage; one Reddit commenter also reported getting useful work done with its free version, while noting it wasn’t automatic. For technical diagrams, text-first graphs, or broader business workflows, compare the options below against what your team actually needs.
01Why people leave Gliffy
You need automatic network mapping
A small organization in a Reddit thread said Gliffy through Confluence had disappointed them while they looked for automatic network diagrams. Manual diagramming and network discovery are different needs.
You want free-first diagramming
A commenter on a network-diagram thread said draw.io let them get a surprising amount done for free, but stressed that it was not automatic.
Your workflow is more specialized
Gliffy is positioned for Confluence teams; alternatives here target text-defined graphs, technical systems, data-driven diagrams, or broader business diagramming.
02The alternatives, ranked by fit
- Best free-first option
draw.iodraw.ioChoose draw.io if you want a capable diagramming option with a free plan and flexible storage. It is also aimed at Confluence or Jira teams, so it is a relevant alternative for teams already using Atlassian tools. One Reddit commenter reported getting useful work done for free, but said it was not automatic—so don’t pick it as a network-discovery tool.
Trade-off: The available information does not establish automatic network mapping.

$5/mofree plan - Best for collaboration
LucidchartLucidchartLucidchart fits teams mapping processes and systems, building org charts from imported data, or linking diagrams to spreadsheets. That makes it a broader collaboration-oriented alternative if your work extends beyond the Confluence use case Gliffy is best known for. The pricing page lists a free plan and a starting price of $9.
Trade-off: Pricing transparency and free-plan limits are drawbacks.

$9/mofree plan - Best for business diagrams
SmartDrawSmartDrawSmartDraw is worth comparing if your team makes varied business diagrams, scaled floor plans, or diagrams automated from data. Those use cases are more specific than simply replacing one diagram editor with another. The listed starting price is $10.95; check the annual commitment and plan limits before switching.
Trade-off: Check the annual commitment and limits before choosing a plan.

$10.95/mo - Best for technical teams
EraserEraserEraser is aimed at technical teams mapping complex systems, standardizing diagrams with templates, and developers using AI coding agents. Consider it if your diagrams are part of technical documentation rather than mainly Confluence-based work. It has a free plan and starts at $42, but the listed seat minimums and AI-credit limits matter.
Trade-off: Seat minimums and AI-credit limits can affect the price.
7.0/10from
$42/mofree plan - Best for Mermaid users
Mermaid ChartMermaid ChartMermaid Chart suits teams that want live co-editing, visual editing for Mermaid diagrams, or workflows involving Claude, VS Code, or Cursor. It is a more specialized choice than a general-purpose diagramming replacement. The listed starting price is $10 with a free plan, but check the annual-only paid plans and conflicting Basic diagram cap.
Trade-off: Paid plans are annual-only; the Basic diagram cap is conflicting.
7.2/10from
$10/mofree plan - Best for text-defined graphs
GraphvizGraphvizGraphviz is a fit for developers who describe graphs in text and need dependency or network diagrams, or output for SVGs and documents. It offers a different working style from a visual editor, so it may suit teams comfortable defining diagrams in text. Pricing details are not published on the vendor's site.
Trade-off: Setup help and pricing details are thin.

Questions people ask
Is draw.io a good Gliffy alternative?
It is a strong option if free-first diagramming or flexible storage is your priority. Our comparison lists a free plan and Confluence or Jira teams among its best-fit users. A Reddit commenter also said they got useful work done for free, while noting draw.io was not automatic.
Does Gliffy automatically generate network diagrams?
The published information does not establish that Gliffy automatically generates network diagrams. A Reddit thread from a small organization seeking that capability said Gliffy had disappointed them. The thread also highlights an important distinction: drawing a network manually is not the same as discovering and mapping it automatically.
Which Gliffy alternative automatically maps a network?
The published information does not confirm automatic network discovery for any alternative here. SmartDraw is listed for automating diagrams from data, and Graphviz for text-defined network diagrams, but neither description confirms automatic topology discovery. Verify that capability directly before switching if it is your main requirement.
