The record

Product: Keyframe.it Studio offers four browser tools for game art: 2D skeletal animation, pixel-art characters, 3D model creation, and image-to-pixel-art conversion.
2D animation: Keyframe.it rigs layered character art with bones and weighted meshes, animates it on a timeline, and exports Spine bundles, sprite sheets, GIFs, or video.
Animation features: The 2D editor lists bones, meshes, inverse kinematics, springs, motion presets, and AI helpers.
Formats and runtimes: Keyframe.it reads and writes Spine format and supports Spine runtimes and PixiJS.
Sprite Puppeteer: Sprite Puppeteer can auto-rig a single sprite, load sprite sheets in up to eight directions, play-test characters, and export for Godot, Unity, GameMaker, or Spine.
MeshForge: MeshForge turns a photo or prompt into a textured 3D model, rigs and animates it in the browser, and renders sprite sheets.
MeshForge cost: Mesh generation uses the user's fal.ai API key and costs about $0.10 per model; rigging, exports, and sprite packs are free.
PixelForge: PixelForge converts drawings, photos, renders, GIFs, and sprite sheets into pixel art and exports PNG, GIF, and sprite sheets.
Integrations: The site lists Godot, Unity, GameMaker, Phaser, Spine, PixiJS, fal.ai, Anthropic, and MCP clients among its integrations or connected services.
AI agent API: Each tool exposes a browser scripting API for agents, and MCP clients can connect using the keyframe-mcp package.
Data handling: Keyframe.it, Sprite Puppeteer, and PixelForge work in the browser and save projects in the browser; the site says data leaves the computer for specified AI generation, AI features, or shared links.
Storage limit: Projects are saved in the current browser on the current computer, and clearing the site's browser data deletes saved work.
Supported browsers: The site says current Chrome, Edge, Firefox, and Safari on a computer are supported; editing is easiest on a larger screen with a mouse and keyboard.
Support and learning: The site provides documentation, guides, examples, and FAQs for its four tools.
