+title: "Run more headless browsers concurrently with Browser Run"
+description: Scale browser automation with more concurrent browsers, faster launches, and higher Quick Actions request throughput by default.

+
+[Browser Run](/browser-run/) lets you automate headless browsers on Cloudflare's global network. Run full browser sessions for interactive workflows, or use [Quick Actions](/browser-run/quick-actions/) for one-request tasks such as screenshots, PDFs, and capturing page content.
+
+If you are on the [Workers Paid plan](/workers/platform/pricing/), your default [limits](/browser-run/limits/#workers-paid) are now higher:
+
+| Limit                           | Previous | New     |
+| ------------------------------- | -------- | ------- |
+| Concurrent browsers             | 120      | **200** |
+| New browser instances / second  | 1        | **3**   |
+| Quick Actions requests / second | 10       | **30**  |
+
+You can now run hundreds of browser sessions in parallel, launch new browsers faster, and process three times as many [Quick Actions](/browser-run/quick-actions/) per second. These published limits are defaults, not maximums. If your workload needs more more concurrent browsers, [request higher limits](https://forms.gle/CdueDKvb26mTaepa9).

 [^1]: Browsers close upon task completion or sixty seconds of inactivity (if you do not [extend your browser timeout](#can-i-increase-the-browser-timeout)). Therefore, in practice, many workflows do not require a high number of concurrent browsers.
