openpilot is developed and tested on **Ubuntu 20.04**, which is the primary development target aside from the [supported embdedded hardware](https://github.com/commaai/openpilot#supported-hardware). We also have a CI test to verify that openpilot builds on macOS, but the tools are untested. For the best experience, stick to Ubuntu 20.04, otherwise openpilot and the tools should work with minimal to no modifications on macOS and other Linux systems.
Test openpilots performance in a simulated environment. The [CARLA simulator](https://github.com/carla-simulator/carla) allows you to set a variety of features like:
* Performance improvements: the tools have been developed on high-performance workstations (12+ logical cores with 32+ GB of RAM), so they are not optimized for running efficiently. For example, `ui.py` might not be able to run real-time on most PCs.
* More tools: anything that you think might be helpful to others.
