WebGL 2
-------
WebGL version
-------------
Until the *OpenGL ES 3* renderer is removed from Godot in favor of *Vulkan*,
HTML5 export uses *WebGL 2* when the *GLES3* option is selected.
Depending on your choice of renderer, Godot can target WebGL 1.0 (*GLES2*) or
WebGL 2.0 (*GLES3*).
.. warning:: Using WebGL 2 is not recommended due to its expected removal
from Godot without replacement.
WebGL 1.0 is the recommended option if you want your project to be supported
on all browsers with the best performance.
WebGL 2 is not supported in all browsers. **Firefox** and
**Chromium** (Chrome, Opera) are the most popular supported browsers,
**Safari** and **Edge** do not work. On **iOS**, all browsers are based on
WebKit (i.e. Safari), so they will also not work.
Godot's GLES3 renderer targets high end devices, and the performance using
WebGL 2.0 can be subpar. Some features are also not supported in WebGL 2.0
specifically.
Godot's WebGL 2 renderer has issues with 3D and is no longer maintained.
Additionally, while most browsers support WebGL 2.0, this is not yet the case
for **Safari**. WebGL 2.0 support is coming in Safari 15 for macOS, and is not
available yet for any **iOS** browser (all WebKit-based like Safari).
See `Can I use WebGL 2.0 <https://caniuse.com/webgl2>`__ for details.
