What Keyframe.it is

Keyframe.it Studio provides four browser-based game-art tools: a 2D skeletal animation editor, a pixel-art character tool, a 3D model creator, and an image-to-pixel-art converter. The 2D editor rigs layered art with bones and weighted meshes, animates it on a timeline, and exports Spine bundles, sprite sheets, GIFs, or video. Listed animation tools include inverse kinematics, springs, motion presets, and AI helpers. It reads and writes Spine format and supports Spine runtimes 3.8 and 4.2, plus PixiJS v7 and v8 through their respective runtimes. Sprite Puppeteer can auto-rig a single sprite, work with sprite sheets in up to eight directions, play-test characters, and export for Godot, Unity, GameMaker, or Spine. MeshForge creates textured 3D models from a photo or prompt and supports browser-based 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 require no account.
