About Us

Bone3 Skeletal Animation (bone3.com) is a team focused on 2D skeletal animation. We built a cloud-based animation editor that runs entirely in your browser—no expensive desktop software, no complicated local setup required.

Ready in your browser: A cloud-native editor with no installation. Projects and assets live in the cloud, so you can pick up your work from any device.

From PSD artwork to animation in one click: Our unique PSD auto-assembly recognizes body parts by layer names, builds bone chains, applies weight binding and IK constraints automatically, and five default animations—idle, walk, run, jump, and attack—turning artwork into animation in minutes.

Two-way compatibility with the Spine ecosystem: Import and export Spine JSON / SKEL data with atlases. Migrate existing assets smoothly and ship results straight to mainstream game runtimes.

Export GIF / MP4 right in the browser: No local rendering environment needed—export animated GIFs and videos with one click, ready to share or publish.

Bilingual interface: Available in English and Simplified Chinese, with more languages to come for creators worldwide.

Bones &: Full support for bones, slots, plain images, mesh images, paths, and point attachments, with rotate / translate / scale / shear transforms.

Skinning & binding: Bone weight binding and per-vertex mesh weight editing for fine, controlled deformation.

** system**: IK, physics, path, and transform constraints for natural, complex motion.

Animation authoring: Parallel multi-track editing, auto keyframing, batch keyframe operations, easing presets with custom Bézier curves, keyframe event callbacks with audio binding previews, and side-by-side management of multiple animations.

Asset management: Quick skin grouping, batch image replacement across groups, outline and deform tools, and drag-to-reorder draw order.

Cloud & export: Cloud storage, one project duplication and reuse, instant skin/image swap previews; export to Spine JSON / SKEL with atlases, animated GIF, and MP4 video.

Game development: Idle, locomotion, and attack animations for mobile and indie games ready to integrate with mainstream game runtimes.

Advertising & operations: User-acquisition creatives, store-page animations, and campaign motion graphics with fast GIF / MP4 delivery.

Web & UI motion: Interactive product-page animations, loading and onboarding effects.

Artwork-to-animation pipelines: Import layered PSD files and auto-bind them—a zero-friction workflow between illustrators and animators.

Teaching & prototyping: The free tier covers the editor's full core workflow—ideal for classroom demos, technical, and rapid prototyping.

The free tier lets you experience the editor's complete core workflow; subscriptions unlock unlimited exports, binary SKEL data, and larger cloud storage. We aim to serve indie developers, small studios, and everyone who loves 2D animation—with a low barrier to entry.
