Vector 2D animation program built around tweening: you set keyframes and Synfig interpolates shapes, transforms and bone rigs between them, instead of drawing every frame. Useful for cut-out style character animation and animated UI.

Status
active: License spot-checked at the source; the entry carries dated evidence.
Version wording: the site and README say GPL v3, and the repository LICENSE is the GPLv3 text, but the source headers read (for example synfig-studio/src/gui/main.cpp) say "version 2 of the License, or (at your option) any later version". The project-level statement is GPLv3 without an "or later", so this entry keeps the bare GPL-3.0
The GPL covers the program. Animations and rendered frames you make are your own work
Filed in tools/ with krita and pixelorama, the other general 2D art and animation editors; animation/ holds clips and capture tools
