 The [Bundle Analyzer](/docs/app/building-your-application/optimizing/bundle-analyzer) can help you investigate large dependencies in your application that may be able to be removed to improve performance and memory usage.
 
+## Run `next build` with `--experimental-debug-memory-usage`
+
+Starting in `14.2.0`, you can run `next build --experimental-debug-memory-usage` to run the build in a mode where Next.js will print out information about memory usage continuously throughout the build, such as heap usage and garbage collection statistics. Heap snapshots will also be taken automatically when memory usage gets close to the configured limit.

+> **Good to know**: This feature is not compatible with the Webpack build worker option which is auto-enabled unless you have custom webpack config.

 You can use an inspector tool to analyze the memory usage of the application.
 
 When running the `next build` or `next dev` command, add `NODE_OPTIONS=--inspect` to the beginning of the command. This will expose the inspector agent on the default port.
