Based on the software "Toonz", developed by Digital Video S.p.A. in Italy, OpenToonz has been customized by Studio Ghibli, and used for the creation of its works for many years. Dwango has launched the OpenToonz project in cooperation with Digital Video and Studio Ghibli. OpenToonz can be used free of charge for both commercial and non-commercial projects.

Synfig Studio is a free and open-source vector-based 2D animation software. It is created by Robert Quattlebaum with additional contributions by Adrian Bentley. Synfig began as the custom animation platform for Voria Studios, and in 2005 was released as free/open source software, under GNU GPL-2.0-or-later

As a true front-end and back-end application, it is possible to design the animation in the front-end, Synfig Studio, and to render it at a later time with the backend, Synfig Tool, on another (potentially faster) computer without a graphical display connected. Incremental and parallel rendering with Synfig Tool is supported by some open source render farm management software, such as RenderChan.

Pencil is a traditional 2D animation software that enables you to create pencil sketches and animated them to create hand-drawn cartoon animations using both bitmap and vector graphics. The program provides several standard drawing tools, including pencil and pen as well as a coloring tool, eraser and a line tool.

You can combine bitmap layers, vector image layers, sound and camera layers and manage each layer`s content from time line display. The finished animation can be exported to X-Sheet, PNG image series or Flash (SWF) animation

Whether you are an animator, modeler, VFX, game developer, 3D Printing, you name it. Blender's got you covered.

Blender's mission is to bring the best 3D technology as tools in the hands of artists, for all platforms, everywhere in the world, free and open source forever.
