Use Node.js inspector API to sample CPU/memory of a Gatsby build


npm i gatsby-plugin-inspector


Add the plugin to your gatsby-config.js file and enable one or both the CPU and memory profiling:

module.exports = {
  plugins: [
      resolve: `gatsby-plugin-inspector`,
      options: {
        cpu: true,
        heap: true,

This should only be enabled for testing as it slows down development and builds by 5-10%.
