See [Gradle platform architecture](platforms.md) for a list of the platforms and more details.

### Gradle runtimes

Gradle is also made up of several different processes that work together to "run the build", such as the Gradle daemon and the `gradlew` command.

Each process, or "runtime", applies different constraints to the code that runs in that process.
