# WebUI (Web Browser)

MSquared supports adding web browsers directly into your experiences. This documentation covers:

* The example content.
* How you can implement browsers in your own project.
* Limitations and expectations.

### Performance and Limitations

* We **strongly recommend** to only use one browser at a time. Using multiple browsers may cause undefined behaviour and problems, as well as performance issues.
* There are optimisations to make the browser run quickly, able to play content at 60FPS without latency. These are currently only supported for Windows, with plans to support Mac in future.
* The browser supports transparency on Windows and Mac, but not for mobile. Keep this in mind if you're planning a long-term project where mobile support might be considered.
* It's important to remember the browser runs locally, so any networked state will need to be carefully considered and implemented.
