Analytics for Unity, Godot and Unreal web exports

Unity, Godot and Unreal web exports compile to WebAssembly and render into a <canvas>, so there’s no JavaScript scene for an analytics tool to read. Uptimizr handles this in two tiers: a JavaScript tier that works immediately with no engine changes, and a bridged tier that adds world-space data through a small shim you copy into your project.

What each tier captures

Section titled “What each tier captures”
Tier Engine code? What you get
JS-only None Pointer and click heatmaps, FPS and long frames, opt-in JS errors
Bridged A small copy-in shim Camera pose and view-direction heatmaps, world-space picks, scene proxy, replay

Start with the JS-only tier. It tells you whether people engage with the export and how it performs, and you can add the bridge later if you need to know what they looked at.

Support by engine

Section titled “Support by engine”
Engine Package Status Bridged tier
Unity WebGL @uptimizr/unity Beta Preview, using a .jslib plugin and a small MonoBehaviour
Godot 4 (web) @uptimizr/godot Beta Available through a copy-in shim
Unreal (web) @uptimizr/unreal Alpha Best-effort, for experimental or community web exports

Unreal needs extra care: Epic has no official UE5 HTML5 or WebAssembly target, and Pixel Streaming runs on a server, so there’s no client-side scene to read. The JS-only tier works with any Unreal canvas, while the bridged tier targets community and experimental Emscripten exports. See the Unreal page for the toolchains involved.

Add the JS-only tier

Section titled “Add the JS-only tier”

Start the connector on the page that hosts your export, before the export boots. This Unity example looks the same for trackGodot and trackUnreal:

Terminal window
npm install @uptimizr/unity
import { trackUnity } from "@uptimizr/unity";


const { client, bridge } = trackUnity({
  projectId: "your-project",
  endpoint: "https://collect.example.com",
  canvas: () => document.querySelector("#unity-canvas"),
});

Data starts flowing straight away. The endpoint is a collector you run yourself.

Add the bridged tier

Section titled “Add the bridged tier”

The bridge is a copy-in asset, not a package, and it does no coordinate maths. It sends your engine’s own world-space values to the connector, which normalizes them. For Unity:

  1. Copy Uptimizr.jslib to Assets/Plugins/WebGL/ in your project.
  2. Copy UptimizrUnityBridge.cs under Assets/ and add the component to a GameObject.
  3. Make sure trackUnity(...) runs on the host page before the export starts.

See the setup for Unity, Godot and Unreal.

Other WebAssembly engines

Section titled “Other WebAssembly engines”

If your engine renders to a <canvas> from WebAssembly, you can use the shared @uptimizr/web-export foundation directly. You supply the engine’s native coordinate frame and get both tiers.
