Effekseer

Effekseer is a free, open-source program for making particle effects for games and movies. It can export work as 2D animations or 3D effects. Version 1.80.7 is listed as available, with additions in version 1.80 including collision settings, new ways to repeat track and ribbon textures, movement-aligned rotation, continuous or triggered spawning, external-model emission sources, and directional billboarding. The tool can load gltf, glb, obj, geo, and bgeo models. Included runtimes support DirectX, OpenGL, Unity, UnrealEngine4, and Cocos2d-x; downloads also offer plugins or libraries for Unity, UnrealEngine, GodotEngine, RPGMakerMZ, WebGL, DXLibrary, and Cocos2d-x. Programmer libraries support DirectX 9/11/12, OpenGL, Metal, and Vulkan. GPU particle simulation and CPU/GPU profiling are preview features and may not work in every environment. The tool and runtime use the MIT license, while texture and effect data use CC-0. Playing effects in a game requires separate runtime or library packages.

Effekseer combines effect authoring with export options and developer libraries for several platforms and engines. Note that playing the effects requires separate runtime or library packages, and GPU simulation and profiling may not be available in every environment.

Effekseer suits game and movie creators who need to build and export particle effects. It may also fit developers working with its listed runtimes, libraries, and integrations.

Effekseer is a free, open-source editor for particle effects in games and movies. It is best for creators who want to author effects and carry them into different engines or graphics APIs. Its broad export and runtime support is a strong draw, though game playback takes additional setup.

Overview

Effects can be exported as 2D animations or 3D effects, giving teams options for different project pipelines. 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, with almost all distributed under CC-0.

On Windows, the editor runs from its Tool directory without modifying the registry or other system settings. That portable arrangement keeps the editor self-contained; it does not, however, include the separate runtime packages 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 let authors shape particle behavior, emission, and trails with more precision, particularly for effects that go beyond simple bursts.

Direct loading of gltf, glb, obj, geo, and bgeo models supports model-based emission workflows. The same release adds GPU-based particle simulation and a CPU/GPU profiler, but both are preview features and may not be available in every environment. They are promising options rather than dependable requirements for a production pipeline.

Effekseer pairs its editor with runtimes and integrations for multiple engines and graphics APIs, including Unity, Unreal Engine, Godot Engine, RPGMakerMZ, WebGL, DXLibrary, and Cocos2d-x. That breadth is useful for developers supporting varied targets, but the separate runtime, Unity, or DX library downloads add an integration step before effects can play in a game.

Pricing

Effekseer costs nothing. The free, open-source plan includes particle effects and runtime export, with no paid tier or usage cap stated. It is a straightforward fit for individual creators and teams that want to avoid a software license fee; the tradeoff is that they must handle runtime setup themselves.

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. This range makes Effekseer relevant to cross-platform projects, while the specific engine or API still determines which package a developer needs.

Who it's for

Effekseer suits game and movie creators who need particle effects in 2D or 3D and developers who value open licensing and multiple runtime targets. It is less suitable for someone seeking an all-in-one editor-and-playback package, since runtime downloads are separate, or for a pipeline that depends on GPU simulation or profiling being universally available.

Pros and cons

Pros

• Free and open source: The MIT-licensed tool and runtime, plus CC-0 texture and effect data, make reuse straightforward.
• Broad integration reach: Engine plugins and programmer libraries cover a wide selection of engines and graphics APIs.
• Useful authoring controls: Version 1.80 adds collision, emission, rotation, trail, and billboarding options, as well as direct support for several model formats.
• Portable Windows editor: Running from the Tool directory without registry changes keeps the application separate from system settings.

Cons

• Playback needs extra downloads: Users must add separate runtime, Unity, or DX library packages to play effects in a game.
• Preview features are conditional: GPU simulation and CPU/GPU profiling may not work in every environment, so they cannot be assumed in a required workflow.

Alternatives

2D Game Animation Software is a broader category to browse when you want to compare tools beyond particle-effect authoring.

Rive is worth considering if collaborative animation work is central: its free plan includes three collaborative files and one project, and it runs across desktop, mobile, and web platforms.

LibreSprite is a free, open-source alternative for creators who want a GPLv2 tool across desktop and Android platforms.

Live2D Cubism, LoongBones, SpriteBrew, Spritelove, Spriter, and Keyframe.it are other options in the animation and sprite-tool space.

Verdict

Choose Effekseer if you need a no-cost, openly licensed particle-effects tool with exports and runtimes aimed at multiple engines and graphics APIs. Its breadth is the main reason to pick it; look elsewhere if you need playback bundled into the editor or require GPU simulation and profiling to work consistently across environments.
