OpenToonz is the most production-minded free 2D tool here. It is based on Toonz from Digital Video in Italy, which Studio Ghibli customized and used in the ink and paint, color design and digital composition stages of almost all of its works, and it is now an open source project launched by Dwango. You get both an xsheet and a timeline, a node tree for compositing effects, raster and vector drawing, anti-aliased lines, and palettes kept separate from paintings so you can paint with provisional colors and change them later. Traditional animators can use GTS, a Ghibli-developed scanning tool for numbered animation sheets, although it runs on Windows only. A plug-in SDK lets developers add effects, and Dwango has released machine learning effects such as style transfer. OpenToonz may be used free of charge for commercial and non-commercial projects. The interface assumes production experience, and parts of the official manuals are in Japanese, which is why Tahoma2D ranks just above it for beginners.

Ambitious hobbyists and students who want a studio-grade 2D pipeline with an xsheet and node effects.
Price
