# multiCompiler

- **Type:** `boolean | { group?: string }`
- **Default:** `true`

`RsdoctorRspackPlugin` automatically detects compilers created during the same startup, creates isolated analysis data for each compiler, and adds a compiler selector to the report. Rsbuild `environments` use their environment names, such as `web` and `node`.

The default compiler keeps the existing `.rsdoctor` output path. Additional compilers are written to `.rsdoctor/compilers/<compilerName>`.

Set this option to `false` when the same process creates unrelated compilers together. You can also explicitly group plugin instances:

```ts
new RsdoctorRspackPlugin({
  multiCompiler: { group: 'ssr' },
});
```
