## Increased Browser Rendering limits!

[Workers](https://developers.cloudflare.com/workers/) [Browser Run](https://developers.cloudflare.com/browser-run/)

[Browser Rendering](https://developers.cloudflare.com/browser-run/) now supports 10 concurrent browser instances per account *and* 10 new instances per minute, up from the previous limits of 2.

This allows you to launch more browser tasks from [Cloudflare Workers](https://developers.cloudflare.com/workers).

To manage concurrent browser sessions, you can use [Queues](https://developers.cloudflare.com/queues/) or [Workflows](https://developers.cloudflare.com/workflows/):

*index.jsjs*

```js
export default {
	async queue(batch, env) {
		for (const message of batch.messages) {
			const browser = await puppeteer.launch(env.BROWSER);
			const page = await browser.newPage();

			try {
				await page.goto(message.url, {
					waitUntil: message.waitUntil,
				});
				// Process page...
			} finally {
				await browser.close();
			}
		}
	},
};
```

*index.tsts*

```ts
interface QueueMessage {
	url: string;
	waitUntil: number;
}

export interface Env {
	BROWSER_QUEUE: Queue<QueueMessage>;
	BROWSER: Fetcher;
}

export default {
	async queue(batch: MessageBatch<QueueMessage>, env: Env): Promise<void> {
		for (const message of batch.messages) {
			const browser = await puppeteer.launch(env.BROWSER);
			const page = await browser.newPage();

			try {
				await page.goto(message.url, {
					waitUntil: message.waitUntil,
				});
				// Process page...
			} finally {
				await browser.close();
			}
		}
	},
};
```
