Rigby2D

By GameSlash

Open-source 2D skeletal animation with MCP-assisted rigging, animation editing and game-runtime exports.

Use cases

Rig layered 2D characters, animate them and export for game runtimes. The built-in MCP server lets a compatible AI assistant inspect projects, validate exports and help edit bones and animation keys.

Getting started

Open the browser editor or download the desktop app from the official site. Import artwork you have rights to use, set up and inspect the rig, then export and test it in your target engine. For AI assistance, follow the MCP setup guide and restrict access to the project folders you intend to share.

Limits and evidence

An animation tool, not a complete game generator. Browser and desktop capabilities differ; check the relevant runtime guide. Code is MIT OR Apache-2.0, while NILA and Rigbytron demo content has a separate restrictive licence. Documentation checked November 2, 2026; no independent end-to-end project test.
