Ranked in these QuestionsQuestion Ranking
Pro Free and open source
Pro Intuitive UI with drag and drop support
For the most part, navigating the editor is pretty intuitive - moving around is done by clicking and dragging the background, clicking on nodes will expand/collapse them, dragging and dropping in files will add them, etc. It also offers shortcuts for power users. For example, ctrl + up/down will rearrange ideas up/down, alt +up/down will zoom in/out, etc.
Pro Lots of export options, including html with folding
Freemind offers many choices when exporting. It allows exporting the project as Java Applet, Flash file, Open Office Writer document, picture (png, jpg), PDF, SVG, multiple variants of (x)html, among other options.
Pro Cross-platform desktop and mobile
Works on Windows, OS X, Linux, iOS and Android.
Pro Good documentation
Pro Fullscreen mode available with a patch
A user-contributed patch is available that adds fullscreen mode to FreeMind.
Pro Can copy entire hierarchy to/from Word with a simple copy/paste action
Freemind allows quickly copying over structure of the mindmap as a bulleted, tab-indented list starting at the node selected. It can also take a bulleted, tab-indented list and create a mindmap from it.
Pro Multi-user support
Pro Supports media files, recognizes URLs and commands
Freemind accepts drag-and-drop for any kind of file, URL or command as part of the mindmap. Files it recognizes, like images, will be displayed. Other files will open in a separate, appropriate application. URLs, links to folders, and executable commands pasted in will be recognized and turned in to clickable links.
Pro Supports node and map encryption
Pro Revision control
Pro Integrates with a good variety of tools
MindManager integrates with MS Office applications (Excel, Outlook, Word, SharePoint), Box.net and many other tools.
Pro Real-time Gantt charts
Data can be represented as a map and as an outline simultaneously.
Con Boring visual appearance
Con Odd UI interaction conventions
Some conventions used to interact with the software are either questionable or simply going against what's commonly accepted. For example, right-click + drag will move around, holding down the right-click will open up the context-menu and left-click in an open space will start a new unconnected node. What this results in is constant accidental opening of context-menu then accidental creation of a new node trying to get out of the context-menu.
