Source: https://doc.babylonjs.com/lite/02-feature-comparison # Feature Comparison — Babylon Lite vs Babylon.js This page maps the feature gap between **Babylon Lite** and **Babylon.js (BJS)**, category by category. It is the honest, detailed view of what Lite supports today, what is partially supported, and what it intentionally won't support — so you can decide whether Lite fits your project. > **Babylon Lite is not a replacement for Babylon.js.** The two engines move forward side by side. Lite optimizes for the smallest bundle and the highest performance on WebGPU; Babylon.js optimizes for the broadest, most mature feature set with WebGL **and** WebGPU support. Closing the gap below is our top priority — features land in Babylon.lite as isolated, tree-shakable modules, so the engine grows without bloating your bundle. ## Legend | Symbol | Meaning | | ------ | ------------------------------------------------- | | ✅ | Supported | | ⚡ | Partial — a subset is implemented; see notes | | — | Not yet available | | 🚫 | Won't support — out of scope by design | | ★ | Lite advantage — area where Lite leads Babylon.js | --- <!-- AUTOGEN:feature-comparison START — generated from lab/lite/docs/feature-comparison.html by scripts/gen-feature-comparison.ts.

These are the most likely candidates to fully finish next. - **— on Lite** means the feature isn't available yet. If your project depends on one of these, Babylon.js is the right option today — and let us know, because your feedback will help shape the Lite roadmap. - **🚫 on Lite** means the feature is intentionally out of scope (e.g. WebGL, the classic `InstancedMesh` API). These reflect deliberate design trade-offs that buy Lite its size and speed; use the noted alternative (e.g. thin instances). This table tracks the current state and will be updated regularly as the gaps close between Babylon.lite and Babylon.js. ## Next steps - 🚀 **[Getting Started](https://doc.babylonjs.com/lite/01-getting-started)** — install Lite, learn the mental model, and render your first scene. - 🛝 **[Lite Playground](https://doc.babylonjs.com/lite/04-playground)** — try covered features live in your browser, no setup required. - 🔁 **[Porting Guide](https://doc.babylonjs.com/lite/03-porting-guide)** — translate a Babylon.js scene to Babylon Lite, side by side. - 🧱 **[Architecture docs](https://doc.babylonjs.com/lite/architecture/00-overview)** — deep dives into the engine internals. - 🏠 **[Welcome](https://doc.babylonjs.com/lite)** — the big-picture introduction and "which engine should I use?" decision tree.
