# Toolchain Images

> Available remote build images and installed tools

A toolchain image is the runner setup for a build: the OS plus Xcode or the
Android SDK. Pin one when your build needs a specific version.

## Selecting an image

If you don't pick one, the platform's current default is used. Pin an image in
config or per invocation:

```yaml theme={null}
build:
  platforms:
    ios:
      image: ios-macos-26-xcode-26.2
```

```bash theme={null}
revyl build --remote --platform ios --image ios-macos-26-xcode-26.2
```

Image precedence is `--image`, then the config `image` field, then the platform
default. The special value `latest` uses the platform default.

PR preview builds accept the same keys via the `image` field in the
[GitHub integration](/integrations/github) config.

## Need a different toolchain?

If your build needs an Xcode, JDK, NDK, or SDK version that isn't listed,
contact [support@revyl.ai](mailto:support@revyl.ai). New toolchain images are
published as additional keys.
