+Experimental features that are not yet stable.
+
+### `experimental.nativeSqlite`
+
+As of Node.js v22.5.0, the `node:sqlite` module is available natively in Node.js.
+This allows Nuxt Content to use SQLite as a database without the need for an external package.
+
+```ts [nuxt.config.ts]
+export default defineNuxtConfig({
+  content: {
+    experimental: { nativeSqlite: true },
+  },
+});
+```
+
+::prose-note
+This feature is only available in Node.js v22.5.0 and above. Enabling this feature in older version will not do anything.
