Configure your confetti using the Party configuration object. This holds all the information on how the confetti will be generated. Almost all properties of a Party object have a default configuration! This makes it super easy to create beautiful and natural looking confetti.

The bare minimum you need is an Emitter to tell how often and how many confetti should spawn, like this:

    emitter = Emitter(duration = 5, TimeUnit.SECONDS).perSecond(30)

But the possibilities are endless! You can fully control how the confetti will be generated and behave by customizing the values of the Party object. An example of a customized Party configuration is this:

    speed = 0f,
    maxSpeed = 30f,
    damping = 0.9f,
    spread = 360,
    colors = listOf(0xfce18a, 0xff726d, 0xf4306d, 0xb48def),
    position = Position.Relative(0.5, 0.3),
    emitter = Emitter(duration = 100, TimeUnit.MILLISECONDS).max(100)

Party options

  • Angle - Int (default: 0): The direction the confetti will shoot. Use any integer between 0-360 or use presets like: Angle.TOP, Angle.RIGHT, Angle.BOTTOM, Angle.LEFT. Angle.RIGHT equates to 0 degrees, and larger values move clockwise from this position.
  • spread - Int (default: 360): How wide the confetti will shoot in the direction of Angle. Use any integer between 0-360. Use 1 to shoot in a straight line and 360 to form a circle
  • speed - Float (default: 30f): The start speed of the confetti at the time of creation.
  • maxSpeed - Float (default: 0f): Set to -1 to disable maxSpeed. A random speed between speed and maxSpeed will be chosen. Using randomness creates a more natural and realistic look to the confetti when animating.)
  • damping - Float (default: 0.9f): The rate at which the speed will decrease right after shooting the confetti
  • size - List<Size> (default: SMALL, MEDIUM, LARGE): The size of the confetti. Use: Size.SMALL, MEDIUM or LARGE for default sizes or create your custom size using a new instance of Size.
  • colors - List<Int> (default: 0xfce18a, 0xff726d, 0xf4306d, 0xb48def): List of colors that will be randomly picked from
  • shapes - List<Shape> (default: Shape.Square, Shape.Circle): Or use a custom shape with Shape.DrawableShape
  • timeToLive - Long (default: 2000): The time in milliseconds a particle will stay alive after that the confetti will disappear.
  • fadeOutEnabled - Boolean (default: true): If true and a confetti disappears because it ran out of time (set with timeToLive) it will slowly fade out. If set to falls it will instantly disappear from the screen.
  • position - Position (default: Position.Relative(0.5, 0.5)): the location where the confetti will spawn from relative to the canvas. Use absolute coordinates with [Position.Absolute] or relative coordinates between 0.0 and 1.0 using [Position.Relative]. Spawn confetti between random locations using [Position.between].
  • delay - Int (default: 0): the amount of milliseconds to wait before the rendering of the confetti starts
  • rotation - Rotation (default: Rotation): enable the 3D rotation of a Confetti. See [Rotation] class for the configuration options. Easily enable or disable it using [Rotation].enabled() or [Rotation].disabled() and control the speed of rotations.
  • emitter - EmitterConfig: Instructions how many and how often a confetti particle should spawn. Use Emitter(duration, timeUnit).max(amount) or Emitter(duration, timeUnit).perSecond(amount) to configure the Emitter.

See Party implementation here


Create a KonfettiView in your compose UI or add one to your xml layout depending on your setup.


    modifier = Modifier.fillMaxSize(),
    parties =,

View-based (xml)

    android:layout_height="match_parent" />
    speed = 0f,
    maxSpeed = 30f,
    damping = 0.9f,
    spread = 360,
    colors = listOf(0xfce18a, 0xff726d, 0xf4306d, 0xb48def),
    emitter = Emitter(duration = 100, TimeUnit.MILLISECONDS).max(100),
    position = Position.Relative(0.5, 0.3)

And that's it! There are endless possibilities to configure the confetti. If you want to learn more on how to implement Konfetti in a java, xml or compose project then see the samples linked at the top of this section

What is the purpose of this library?

To have a lightweight particle system to easily generate confetti particles to celebrate little and big moments. Even though this is a particle system the purpose is not to be a fully fledged particle system. Changes and features are meant to be in line with being a confetti library. A great example is the implementation of custom shapes by @mattprecious here.
