Ajax Animator is primarily written using JavaScript, the Ext JS framework, and HTML5-related technologies such as SVG.

Development started around March 2006, based on the RichDraw JavaScript library, which allowed for in-browser graphics creation.

[3][6] The application was soon rewritten to use the DHTML Suite library from DHTML Goodies, and finally allowed for exporting SWF files through the Freemovie Java library.

Development subsequently moved to Subversion on Google Code to ease production.

Later versions used the author's own VectorEditor library, based on the Raphaël framework.
