Description
Charios is a browser-native 2D character animation tool that lets creators animate a game character within minutes. You drop layered PNGs onto a fixed-skeleton rig, snap them to bones, and start animating without any download, compilation, or configuration, since Charios runs as a web app.

It supports retargeting humanoid motion capture: you can drag in any humanoid .bvh from sources like CMU, Truebones, or Rokoko, or a humanoid .fbx, and the retargeter normalizes bone lengths automatically and extrapolates hand and foot bones when the source rig does not expose them. Additional features include body-shape proportional editing and a 9-cell animation-check grid for previewing motion. Finished work can be exported as a GIF or Unity prefab, with a JSON skeleton available and Godot import on the roadmap.
Charios is free forever for up to three active projects with every editor feature unlocked. Paid plans remove the project cap, raise upload limits, and add PNG-sequence and JSON export, with a Studio tier for teams. The editor is desktop-first for precise rigging input, while dashboards and previews work on any device.
