OpenToonz

Italian software studio Digital Video created Toonz in 1993, which Studio Ghibli customized to run its feature film animation pipeline. Media company Dwango open-sourced the suite as OpenToonz in 2016 to preserve that traditional workflow for independent creators. Today, the desktop program gives animators a complete hand-drawn 2D production environment with digital ink-and-paint, exposure sheets, and scanning utilities.

Why OpenToonz instead of Adobe After Effects

OpenToonz is engineered for hand-drawn character animation and classical studio pipelines. Artists work directly with raster and vector drawing levels, timing every frame on an exposure sheet or a horizontal timeline. Built-in palette tools separate outlines from color fills, meaning that altering a color swatch updates painted frames across an entire scene instantly. For studios maintaining physical drawing traditions, the integrated GTS utility scans and cleans paper sketches directly into digital levels for inking.

Adobe After Effects approaches animation through motion graphics, transform keyframes, and video compositing layers. While After Effects handles kinetic typography, shape transitions, and camera effects with ease, creating frame-by-frame character movement inside it is cumbersome without third-party plugins. OpenToonz skips motion graphics templates in favor of drawing light tables, onion skinning, and automated vector in-betweening. Animators seeking dedicated hand-drawn character tools find a direct fit in OpenToonz, whereas After Effects remains built for compositing and motion design.

What it does well

• Dynamic color palettes let artists recolor character fills across hundreds of drawings instantly, because swatches link directly to painted areas instead of baking pixels.
• Dual vector and raster levels give illustrators a choice between textured freehand pencil brushes and mathematical vector strokes editable with control points.
• Exposure sheet and horizontal timeline layouts let creators organize frame timing, layer exposures, and camera motion to match their workflow.
• Automated vector in-betweening generates transitional drawings between keyframes, reducing the manual workload needed for smooth movement.
• Dedicated GTS scanner integration cleans up and binarizes physical paper sketches, keeping hand-drawn lines intact for digital coloring.
