Gliffy

Gliffy is a powerful yet intuitive diagramming tool developed by Perforce that enables individuals and teams to create professional visual communication assets quickly and efficiently. Through its drag-and-drop interface, users can build a wide variety of diagrams — including flowcharts, UML diagrams, entity-relationship diagrams, network diagrams, cloud architecture diagrams, org charts, mind maps, and swimlane diagrams — either using pre-built templates or by writing diagram-as-code with Mermaid.js. The platform is best known for its deep integration with Atlassian products, making it the most popular diagramming app in the Atlassian Ecosystem with over 18 million users diagramming directly within Confluence and Jira, though it also operates as a standalone tool called Gliffy Online for teams outside the Atlassian environment. It is particularly well-suited for software engineers, IT professionals, business analysts, and project managers across organizations of all sizes — from small businesses to large enterprises — in industries such as technology, financial services, and information security. Gliffy solves the challenge of translating complex technical concepts and project plans into clear, collaborative visuals that keep cross-functional teams aligned, supporting use cases like software documentation, process mapping, cloud infrastructure visualization, database design, UX wireframing, and real-time collaborative brainstorming sessions.
