I realize this is an older discussion, but I’m posting this note for anyone who stumbles upon this topic for the first time...

I’m developing the plugin called TLabWebview, a 3D web browser plugin released as open-source software on GitHub, where all features are available for free. It only supports Android platforms, for the VR device, such as the Meta Quest series. However, it works with multiple browser engines (WebView and GeckoView), supports multi-instance functionality, and can render to various targets, including Texture2D and CompositionLayers.

The documentation and API may not be as detailed as those of paid alternatives, but I’m actively enhancing them based on input from users.

I’m optimistic about the plugin’s efficiency since it captures the web browser frame as a byte array and transfers it directly to Unity without any pixel format adjustments (this is a reliable choice for the plugin’s rendering mode). When you opt for HardwareBuffer as the rendering mode, Texture2D and the web browser frame are aligned using HardwareBuffer, making it more efficient than transferring frame pixel data via the CPU.
