What is Rigby2D?

Rigby2D is a free, open-source 2D skeletal animation editor for games and film.

Rig a character with bones, weighted meshes, IK, physics and clipping, or let AutoRig turn a layered PSD into an editable rig in one step. Animate with a dopesheet, graph editor, onion skin and pose library. Render film with a camera, audio tracks and lip-sync from audio to PNG sequences, WebM with alpha or MP4 at 4K.

Ship the same character to Godot, Unity, Phaser, JavaScript or Rust with free, open-source runtimes: no license fee and no revenue limit. Rigby2D opens Spine (3.8 to 4.3) and DragonBones projects directly, so you can bring your existing characters.

Also: Python scripting and an add-on marketplace, a built-in MCP server for AI assistants, and the full editor in your browser with nothing to install.
