Unity’s WebGL/HTML5 export was designed to bring existing games to the browser, not to build web‑native experiences. The result is long build times, massive downloads and missing features like dynamic shadows. Even an empty Unity project can exceed 25 MB. Wonderland Engine takes the opposite approach: it was designed for the browser from day one. Our WebAssembly runtime is roughly 1 MB, builds take seconds and features like real‑time shadows and physics run smoothly. For quick ports of a simple scene Unity might suffice; if you care about web performance and iteration speed, Wonderland Engine is the right tool.
What makes Wonderland Engine better for web?
Fast iteration
Unity’s build-and-run cycle for WebGL often takes 15 minutes or more, even for small projects. Wonderland Engine builds in under a second, so you can test changes instantly.
Small runtime
Empty Unity projects can exceed 25 MB and require decompressing huge JavaScript/wasm bundles. Wonderland Engine’s runtime is about 1 MB and only downloads the code you need.
Performance on the web
Many of Unity’s features don’t work with WebGL export and apps suffer from lower frame rates. Wonderland Engine is optimized for WebGL/WebXR from the start, supporting dynamic lighting and high frame rates.
Web‑native ecosystem
Wonderland Engine integrates with npm and web tooling and outputs plain HTML files; Unity projects remain tied to proprietary tooling and are difficult to integrate with modern web frameworks.
