Free Noise Texture Generator for Games: FastNoise Lite
Browser based live preview of an open source noise texture generator. Create Perlin, Simplex, or Voronoi noise textures for use in games. Export PNG files without coding!
I often work with folks who want to create small games with AI agents. Inevitably, they will ask me about textures. More specifically, how to create noise textures for things like terrain, stone walls, water, clouds, etc. It’s too time consuming to search for a quality free noise texture and manually creating them in Photoshop is not very vibey.
Enter FastNoise Lite, an open source noise generator library with a twist. There is also a browser based preview tool that doesn’t require installation! Play around with the sliders and then export a PNG.

It includes Perlin, Simplex, Cellular (Voronoi), Value and many other types of noise that mimic natural materials. All of these textures (stone, grass, water waves, cloud layers) begin with noise. With this browser based preview tool, you can visually create and manipulate the noise before you even start coding!
How to generate seamless noise textures in the browser
You can check out the preview tool here: auburn.github.io/FastNoiseLite. Once you load it up, you should see some realtime generated noise. You can change the noise type, frequency, octaves, and lacunarity by moving the sliders. The preview image will update automatically. If you see something you like, click the Export button to save the image as a PNG. This is all you need to do if you don’t know how to code. Just generate some noise, drop it onto your agent, and tell it where to use it.
How to use FastNoise Lite in a JavaScript project
For those of you who have AI agents creating web games or other procedurally generated content, you can install FastNoise Lite via npm. Once installed, your agent can easily create noise arrays within your project. This is great for terrain height maps, dynamic backgrounds, random dungeons, or any other visual effect that requires some organic variation.
npm install fastnoise-lite
Your agent can then easily create an array of noise values. Here is some sample code that you can copy and paste directly into your chat window and ask your agent to modify it based on your project’s requirements (grid size, noise type, etc):
What noise types does FastNoise Lite include
- 1Perlin noise — the classic organic look used for terrain and cloud layers
- 2OpenSimplex2 — smoother than Perlin with fewer directional artifacts
- 3Cellular (Voronoi) — cell-based patterns that look like stone, cracked earth, or biological textures
- 4Value noise — blocky gradient noise for stylized or retro visual styles
- 5Fractal layering for all types: FBm, Ridged, PingPong — adds natural detail on top
FastNoise Lite includes a native GML package (FastNoiseLite.yymps) that you can import directly into Game Maker Studio as a local package. Once imported the scripts are immediately available in any object or room, no extra setup.
A free, browser-based noise texture generator with live preview and PNG export — no account, no install, no waiting. If your agent writes JavaScript you also get an npm package that handles procedural generation directly in the project. Either way your game stops looking like it uses placeholder assets.
