+
+Durable Objects can now be used with zero commitment on the [Workers Free plan](/workers/platform/pricing/) allowing you to build AI agents with [Agents SDK](/agents/), collaboration tools, and real-time applications like chat or multiplayer games. 
+
+Durable Objects let you build stateful, serverless applications with millions of tiny coordination instances that run your application code alongside (in the same thread!) your durable storage. Each Durable Object can access its own SQLite database through a [Storage API](/durable-objects/best-practices/access-durable-objects-storage/). A Durable Object class is defined in a Worker script encapsulating the Durable Object's behavior when accessed from a Worker. To try the code below, click the button: 
+
+[![Deploy to Cloudflare](https://deploy.workers.cloudflare.com/button)](https://deploy.workers.cloudflare.com/?url=https://github.com/cloudflare/templates/tree/staging/hello-world-do-template)
+
+```js
+import { DurableObject } from "cloudflare:workers";
+
+// Durable Object
+export class MyDurableObject extends DurableObject {
+  ...
+	async sayHello(name) {
+		return `Hello, ${name}!`;
+	}
+}
+
+// Worker
+export default {
+	async fetch(request, env) {
+		// Every unique ID refers to an individual instance of the Durable Object class
+		const id = env.MY_DURABLE_OBJECT.idFromName("foo");
+
+		// A stub is a client used to invoke methods on the Durable Object
+		const stub = env.MY_DURABLE_OBJECT.get(id);
+
+		// Methods on the Durable Object are invoked via the stub
+		const response = await stub.sayHello("world");
+
+		return response;
+	},
+};
+```
+
+Free plan [limits](/durable-objects/platform/pricing/) apply to Durable Objects compute and storage usage. Limits allow developers to build real-world applications, with every Worker request able to call a Durable Object on the free plan.

+title: SQLite in Durable Objects GA with 10GB storage per object
+description: SQLite-backed Durable Objects are generally available.
+products:
+  - durable-objects
+  - workers 
+date: 2025-04-07T06:00:00Z
+---
+
+SQLite in Durable Objects is now generally available (GA) with 10GB SQLite database per Durable Object. Since the [public beta](https://blog.cloudflare.com/sqlite-in-durable-objects/) in September 2024, we've added feature parity and robustness for the SQLite storage backend compared to the preexisting key-value (KV) storage backend for Durable Objects. 
+
+SQLite-backed Durable Objects are recommended for all new Durable Object classes, using `new_sqlite_classes` [Wrangler configuration](/durable-objects/best-practices/access-durable-objects-storage/#create-sqlite-backed-durable-object-class). Only SQLite-backed Durable Objects have access to Storage API's [SQL](/durable-objects/api/storage-api/#sql-api) and [point-in-time recovery](/durable-objects/api/storage-api/#pitr-point-in-time-recovery-api) methods, which provide relational data modeling, SQL querying, and better data management.
+
+```js
+export class MyDurableObject extends DurableObject {
+  sql: SqlStorage
+  constructor(ctx: DurableObjectState, env: Env) {
+    super(ctx, env);
+    this.sql = ctx.storage.sql;
+  }
+
+  async sayHello() {
+    let result = this.sql
+      .exec("SELECT 'Hello, World!' AS greeting")
+      .one();
+    return result.greeting;
+  }
+}
+```
+
+KV-backed Durable Objects remain for backwards compatibility, and a migration path from key-value storage to SQL storage for existing Durable Object classes will be offered in the future.
+
+For more details on SQLite storage, checkout [Zero-latency SQLite storage in every Durable Object blog](https://blog.cloudflare.com/sqlite-in-durable-objects/).
