There are two established players in diagramming apps for Confluence Server.
While Gliffy is the oldest diagramming app in the Atlassian environment, draw.io has been the highest rated Confluence app in the Atlassian Marketplace since 2013.
You can make diagramming faster and easier by customizing the draw.io interface in Confluence server instances. Save a lot of time, frustration and effort by customizing the draw.io interface to provide you with the shapes, fonts, colors and more that you consistently need, by default. → Learn more about this Feature.
Visio import and export
Gliffy comes with an import function for Visio files. But with draw.io you can also export your draw.io diagrams to Visio (.vsdx - .vsd and .vsx on Cloud and on Server after Configuration) files so they can be opened in Microsoft's diagramming tool.
Lower license costs
draw.io has significantly cheaper license costs. You can save up to 50% of your costs immediately! Please check our pricing overview to get detailed information.
Strong support & innovation
draw.io has a personal and fast support that is fully backed by the founders. The product releases new versions every 14 days. draw.io is an open source technology stack for building diagramming applications and it comes with a free web app.
Import diagrams via drag & drop
You can simply import various diagram formats via drag & drop (XML, Gliffy, VSDX), as well as importing images (JPG, PNG, SVG, GIF).
Gliffy mass import
Do you have multiple Gliffy diagrams in your Confluence instance that need to be converted into native draw.io diagrams? Visit our Gliffy Mass Import portal (Confluence Server only) to see how you can import all your Gliffy diagrams into draw.io with just one click!
With draw.io, your diagram data is only stored on in your browser and where you have chosen to save your diagram - in your Confluence or Jira instance on your own server or in the Atlassian Cloud.
Because no third party stores or accesses your diagram data, you can confidently include draw.io in your secure tool stack and gain certifications under the data protection ISO standards.
Revision history of all changes
All changes made to a page or a draw.io diagram within a page are logged in the Confluence version history (must have for ISO 9001). You can quickly and easily access all changes via Confluence's page history.
Automatic layout function
This function lets you quickly build up collections of diagram elements. A number of commonly used arrangements are available (horizontal and vertical flow, horizontal and vertical tree, organic and circle). Watch this video to understand how it works.
Many use cases
The ways in which diagrams are used in Confluence are endless. draw.io provides you with graphic components for many use cases and diagram types.
