Synfig Studio
An open-source 2D animation package with bones, deformation, keyframes, vector layers, and procedural parameters.
Why it’s here
Tweening reduces frame-by-frame drawing for cutscenes, character parts, moving backgrounds, and promo prototypes.
Best fit
Art, animation, audio, levels, and narrative turn mechanics into a believable world.
Before you commit
Its interface and render pipeline take adjustment; engine delivery usually requires baked frames, video, or custom data.
