Effekseer vs SpineBones

Effekseer is a free, open-source tool for creating particle effects for games and movies. It exports effects as 2D animations or 3D effects, with runtimes available for Windows, Mac OS X, Linux, iOS, Android, and Emscripten. Included runtimes support DirectX, OpenGL, Unity, UnrealEngine4, and Cocos2d-x; separate downloads also provide plugins or libraries for GodotEngine, RPGMakerMZ, WebGL, DXLibrary, and other listed integrations. Programmer libraries support DirectX 9/11/12, OpenGL, Metal, and Vulkan. The listed available version is 1.80.7. Version 1.80 adds collision settings, UV repetition for tracks and ribbons, movement-aligned rotation, additional spawning options, external-model emission sources, and directional billboarding. It supports direct loading of gltf, glb, obj, geo, and bgeo models. GPU particle simulation and CPU/GPU profiling are preview features that may not be available in all environments. The tool and runtime use the MIT license; texture and effect data use CC-0. Playing effects in a game requires separate runtime or library packages.

SpineBones is a free 2D skeletal animation editor for creating bone rigs, keying motion, and exporting animations. Rigging includes hierarchies, re-parenting, grouping, and inverse kinematics. Its timeline supports keyframe insertion, movement, selection, copying, looping, per-key easing, and audio tracks. Slots accept PNG, JPG, SVG, and WebP artwork, with multiple attachments and frame-by-frame swaps. Attachment meshes can be deformed with keyed vertices, and onion skin shows neighboring poses. SETUP stores the base pose; ANIMATE keys position, rotation, and scale. Exports include WebM video, transparent PNG sequences, sprite sheets with atlas data, and portable .sbn packages; legacy .json projects open too. An MCP bridge supports Claude and other MCP clients for rig elements, keyframes, frame-rate changes, and exports. It runs on macOS 12+ and Windows 10+, with no account, licence key, or trial timer.
