Profiling your application is the best way to measure its performance. You can use different profiling tools to understand where there might be any issues with elements of your application including memory usage, CPU performance, GPU performance, and your custom scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like.

See in Glossary.
Unity has several profiling and analysis tools to measure the performance of your application:
| Tool | Description |
|---|---|
| ProfilerA window that helps you to optimize your game. It shows how much time is spent in the various areas of your game. For example, it can report the percentage of time spent rendering, animating, or in your game logic. More info See in Glossary |
Measures the performance of the Unity Editor, your application in Play mode, or connects to a device running your application in development mode. |
| Memory Profiler | Provides in-depth memory performance analysis. |
| Profiling Core package | Provides APIs you can use to add contextual information to Unity Profiler captures. For more information, refer to Adding profiling information to your code. |
| Profile Analyzer | Compares two profiling datasets together to analyze how your changes affect your application’s performance. |
| Frame Debugger | Provides a way to measure the graphical performance of your application. |
| Project Auditor | Creates a report that describes issues about the scripts, assets, and code in your project. |
Alongside the Unity Profiler, use platform-specific profiling tools to ensure your application runs as expected. These tools have the most utility on platforms that can use IL2CPPA Unity-developed scripting back-end which you can use as an alternative to Mono when building projects for some platforms. More info
See in Glossary to produce a C++ version of the project. These native code versions provide transparent call stacks and high-resolution method timings that are unavailable when running under Mono.
The following list provides some examples of available profiling tools. You can also use Unity’s low level native plug-in Profiler API to export profiling data to third-party profiling tools.
