Gliffy 10.x (2025 Edition)
The definitive diagramming tool for the Atlassian ecosystem. The late 2025 update (v10) introduces 'Gliffy AI' for prompt-to-diagram generation, Mermaid-to-Gliffy conversion, and the breakthrough 'Zero Egress' security model for Confluence Cloud. While it offers the deepest Jira/Confluence integration available, its standalone 'Online' version faces stiff competition from AI-native tools like Eraser and the free, open-source power of diagrams.net.
