Before you choose
Compare free and paid access
Look for tools with free plans in this directory. Graphviz is open source, while Graphistry and Kumu use freemium models. Kumu shows paid access starting at $9 per month and offers a 14-day trial.
Review the features included at no cost before selecting a paid tier. A free trial can help you assess fit before a subscription.
Choose a deployment that fits your workflow
This collection includes browser-based software and tools for Windows, Linux, and macOS. Look for products that expose an API or allow self-hosted deployment.
Choose a local desktop tool when files must stay on a computer. Choose web or self-hosted software when access and deployment control matter.
Evaluate the graph data model
Compare how a tool represents nodes, links, attributes, and relationships. The graph data model affects how you import data and build views.
Confirm that the model matches the structure of your project before you commit to a tool.
Look for filtering and team work
Interactive filtering helps narrow a graph while you explore it. Team collaboration supports shared work around the same visual analysis.
Compare these fields with your review process, especially when several people need to inspect or change a graph.
Review scripting and export
Scripting or API support can connect graph views to other software and repeat tasks. Export formats determine how you share diagrams or move results into another tool.
Check the formats you need and whether the tool exposes the operations your workflow requires.
