VERDICT

Should I use Gephi?

The Open Graph Viz Platform - gephi.org

Worth it. Buy if you need serious network-graph analysis and can climb a learning curve — it is free and the academic standard. Skip it if you want hosted, collaborative visualization or vendor support.

Confidence

Medium. Based on ~50 public sources: vendor site, GitHub, G2, Reddit, and academic comparisons. User-review volume is small.
