LoongBones
What it is
LoongBones is a 2D skeletal animation solution with a browser-based editor and a runtime player. The HTML5-and-canvas editor requires no installation and is used to create, modify, and export animation data, images, frame sequences, and other digital assets. Its documented tools include mesh deformation, bone binding, inverse kinematics, collision, and mesh curve deformers. The editor can import PSD files, images, texture atlases, LoongBones projects and data, and supported Spine files, including Spine 3.8.75 data with atlas files. It exports animation formats, images, sprite sheets, and GIFs; plugins support additional import and export formats. The runtime plays animation data on Egret, Cocos, PixiJS, Unity, and Unreal, and is free to download from GitHub under the MIT License. LoongBones also says it supports AI-generated animation and has integrated DeepSeek. A seven-day free experience includes 100M of storage and up to 10 projects. Membership costs CN¥19.90 a month or CN¥199.90 a year. The terms state that membership is a virtual product and does not support refunds after taking effect.
