What Keyframe.it is

Keyframe.it Studio brings four browser-based tools for game art together: a 2D skeletal animation editor, a pixel-art character tool, a 3D model creator, and an image-to-pixel-art converter. In the 2D editor, users rig layered art with bones and weighted meshes, animate it on a timeline, and export Spine bundles, sprite sheets, GIFs, or video. Listed features include inverse kinematics, springs, motion presets, and AI helpers. The editor reads and writes Spine format, supports Spine runtimes, and provides PixiJS targets.

Sprite Puppeteer can auto-rig a sprite, load sprite sheets in up to eight directions, play-test characters, and export for Godot, Unity, GameMaker, or Spine. MeshForge creates a textured model from a photo or prompt, then supports browser rigging, animation, and sprite-sheet rendering. Model generation uses the user's fal.ai API key and costs about $0.10 per model; rigging, exports, and sprite packs are free. PixelForge converts drawings, photos, renders, GIFs, and sprite sheets into pixel art, with PNG, GIF, and sprite-sheet exports. The tools are free and need no account, but projects are saved in the current browser on the current computer.
