When 9 Story took over production from CINAR/Cookie Jar starting with season 16, the show switched to Adobe Flash, but when Oasis Animation took over starting with season 20, it switched to Harmony. Arthur - used traditional animation with digital ink and paint from season 1 to 15.The third product, Harmony Server, is meant to help synchronize the works of large studios by acting as a repository for animation assets and storage. Toon Boom used to have separate programs for storyboarding, animating, entire production pipelines, and children's learning, but have simplified the pipeline in the latest version into just three pieces of software- Harmony for all animation tasks, and Storyboard Pro for storyboarding and concept visualization. Harmony has capabilities that emulate an animator's drafting table, network nodes, built-in automated lip-syncing functions, built-in 3D modeling and intergration, and quality rendering directly from the program.

It has tools for both traditional frame-by-frame animation and 'puppet rig'-style animation. While Flash has been used more frequently for television/movie animation entertainment for years, it was actually built for interactive web design, thus making it a bit of a curve to create content for other areas, and Harmony's software was developed to solve this by tailoring it to the creative cartoon animator's needs instead. Harmony is also fairly affordable for both professionals and amateurs alike. Harmony (previously Toon Boom Studio), along with Adobe Flash, are the go-to software for modern-day 2D digital animators due to their low cost and potential shortcuts that are not offered with traditional ink-and-paint animation. Harmony is a digital animation software package produced by Canadian company Toon Boom Animation, Inc.
