Effekseer

Effekseer is a free, open-source tool for making particle effects for games and movies. It is best suited to creators who need effects they can carry across multiple engines and graphics APIs. Its broad runtime reach is compelling, but using effects in a game means downloading a separate runtime package.

Overview

Effects can be exported as 2D animations or 3D effects, so Effekseer can serve projects with different output needs. The tool and runtime use the MIT license, while texture and effect data are CC-0. User-contributed sample effects are free to use and edit in games or movies, and almost all are distributed under CC-0.

On Windows, the editor runs from its Tool directory without changing the registry or other system settings. That makes it easy to keep the editor self-contained, but it does not bundle the runtime needed to play effects in a game.

Key features

Version 1.80 adds collision settings, repeated UVs for tracks and ribbons, movement-aligned rotation, continuous and trigger-based spawning, external-model emission sources, and directional billboarding. These controls give effect authors more ways to shape particle motion, emission, and trails, making the tool a stronger fit for effects that need more than simple bursts.

Direct loading of gltf, glb, obj, geo, and bgeo models supports model-based sources without requiring a separate conversion step in the stated workflow. Version 1.80 also introduces GPU-based particle simulation and a CPU/GPU profiler, but both are preview features that may not work in every environment. They are promising additions, not capabilities to rely on for every production setup.

Pricing

Effekseer costs nothing and is free and open-source. The free plan includes particle effects and runtime export, with no paid tier or seat limit stated. The main practical cost is setup rather than subscription: game playback requires separate runtime, Unity, or DX library packages.

Platforms

The editor is available for Android, iOS, Linux, macOS, web, and Windows. Included runtimes support DirectX, OpenGL, Unity, UnrealEngine4, and Cocos2d-x, with effects available on Windows, Mac OS X, Linux, iOS, Android, and Emscripten. Programmer libraries support DirectX 9/11/12, OpenGL, Metal, and Vulkan; official downloads also include plugins or libraries for Unity, UnrealEngine, GodotEngine, RPGMakerMZ, WebGL, DXLibrary, and Cocos2d-x. This is an unusually broad set of integration paths, though users should expect to select and download the package that matches their target.

Who it's for

Effekseer suits game and movie creators who need to author particle effects and want the option to target multiple engines or graphics APIs. Its open licensing and reusable sample effects also suit projects that value freely usable assets. It is a less direct fit for someone seeking an all-in-one editor-and-runtime installation or a tool focused on character animation rather than particles.

Pros and cons

• Pros: Free and open-source, with MIT-licensed tool and runtime and CC-0 texture and effect data, making reuse and integration flexible.
• Pros: Broad runtime, API, and plugin support gives developers several routes to bring effects into game projects.
• Pros: Version 1.80's model loading and particle controls support more varied effect workflows.
• Cons: Separate runtime packages add a setup step before effects can play in a game.
• Cons: GPU simulation and profiling are preview features and may not be available in all environments.

Alternatives

For a broader set of animation tools, browse 2D Game Animation Software. Choose Rive instead if you want a freemium editor with a free plan for 3 collaborative files and 1 project. LibreSprite is another free, open-source option for readers comparing animation software.

SkelForm is a free, open-source 2D skeletal animator, so consider it when skeletal animation is the priority. SpineBones offers a free plan with a 300-frame timeline, playback up to 120 FPS, and WebM, PNG sequence, and sprite sheet exports. Spriter has a free version for PNG and spritesheet animation with basic animation features.

Live2D Cubism is another option with a free plan and trial. Keyframe.it is a free web-based alternative, while Phluxel is a freemium option for Windows.

Verdict

Choose Effekseer if you need a free, open-source particle-effect tool with broad runtime and graphics API support. Its main advantage is the range of ways to take effects into projects; look elsewhere if you need a bundled playback runtime or a dedicated skeletal-animation workflow.
