## What it is
Synfig Studio is a free and open-source 2D animation application for creating film-quality animation from vector and bitmap artwork. It uses automatic tweening instead of frame-by-frame drawing, with layers, filters, and a bone system for cutout animation.

## Use cases
- create 2d animated films with vector artwork
- tween vector shapes without drawing frame by frame
- cutout character animation with a bone system
- animate bitmap artwork with skeleton distortion
- free alternative to proprietary 2d animation software

## When to choose
- you need film-quality 2D animation without frame-by-frame drawing
- you work with vector or bitmap artwork and want automatic inbetweening
- you need cutout/puppet animation with bones on Windows, Linux, or macOS
- you want a free GPL-licensed animation studio

## When to avoid
- you need frame-by-frame raster animation tools like those in traditional animation suites
- you need 3D animation
- you need a lightweight web-based animation tool
- you require deep integration with proprietary animation pipelines

## Facets
- artifact type: application
- maturity: active
- function: animation, graphics, image-processing
- domain: graphics, media, cross-platform
- platform: windows, cpp
- tags: 2d-animation, vector-graphics, tweening, cutout-animation, gtkmm, open-source, linux, macos, desktop
