Availability: Free Download
Comparable: After Effects, Sketchup

Blender is a free and open source 3D animation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. Advanced users employ Blender’s API for Python scripting to customize the application and write specialized tools; often these are included in Blender’s future releases. Blender is well suited to individuals and small studios who benefit from its unified pipeline and responsive development process. Examples from many Blender-based projects are available in the showcase.

Blender is cross-platform and runs equally well on Linux, Windows and Macintosh computers. Its interface uses OpenGL to provide a consistent experience. To confirm specific compatibility, the list of supported platformsindicates those regularly tested by the development team.

As a community-driven project under the GNU General Public License (GPL), the public is empowered to make small and large changes to the code base, which leads to new features, responsive bug fixes, and better usability. Blender has no price tag, but you can invest, participate, and help to advance a powerful collaborative tool: Blender is your own 3D software.

Availability: Free Download
Comparable:  Dreamweaver

BlueGriffon takes a straightforward WYSIWYG (What You See Is What You Get) approach to web editing, but also manages to include plenty of more powerful features.  It is based on the rendering engine of Mozilla Firefox.

You could just use it to type text, insert images, tables, audio files, videos and so on. But there’s also an SVG editor, form design tools, some CSS support, an accessibility checker, DOM Explorer, and more.

BlueGriffon is free but does utilize commercial plugins, so you may find that some features link you to a web store to purchase these plugins.

Categories: Productivity & Utility

dialogoAvailability: Free download
Comparable: Visio

Dia is free and open source general-purpose diagramming software, roughly inspired by Microsoft Visio. Dia uses a controlled single document interface (SDI) similar to GIMP and Inkscape.

Dia has a modular design with several shape packages available for different needs: flowchart, network diagrams, circuit diagrams, and more. It does not restrict symbols and connectors from various categories from being placed together.

Dia has special objects to help draw entity-relationship models (obsoleted tedia2sql or newer parsediasql can be used to create the SQL DDL), Unified Modeling Language (UML) diagrams, flowcharts, network diagrams, and simple electrical circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of Scalable Vector Graphics (SVG) to draw the shape.

Dia loads and saves diagrams in a custom XML format which is, by default, gzipped to save space. It can print large diagrams spanning multiple pages and can also be scripted using the Python programming language.

Dia is available for Windows, Mac, and Linux and is available to download at no cost here.

Availability: Free Download
Comparable: Inspiration, yEd Graph Editor

FreeMind is a free, open source mind mapping application written in Java.  It provides extensive export capabilities. It runs on Microsoft Windows, Linux and Mac OS X via the Java Runtime Environment.

As with other mind mapping software packages, FreeMind allows the user to edit a hierarchical set of ideas around a central concept. The non-linear approach assists in brainstorming new outlines and projects as ideas are added around the mind map. As a Java application, FreeMind is portable across multiple platforms and retains the same user interface, causing some amount of variation from the common interface on each platform. Mac users may notice the most difference from their traditional user interface, but  the software’s features should still appeal to the segment of users who accept function over form.
