+### What are the usage limits and pricing tiers for Cloudflare Browser Rendering and how do I estimate my costs?
+
+#### Usage Limits
+
+| Plan     | Concurrent Browsers | New Instances/min | Browser Timeout | REST API Calls/min |
+| :------- | :------------------ | :---------------- | :-------------- | :----------------- |
+| **Free** | 3 per account       | 3 per minute      | 60 s            | 6 per minute       |
+| **Paid** | 10 per account      | 10 per minute     | 60 s            | 60 per minute      |
+
+By default, idle browser sessions close after 60 seconds of inactivity. You can adjust this with the [`keep_alive` option](/browser-rendering/platform/puppeteer/#keep-alive).
+
+#### Pricing
+
+Browser Rendering is currently free up to the limits above until billing begins. Pricing will be announced in advance.
+
+### Does Browser Rendering rotate IP addresses for outbound requests?
+
+No. Browser Rendering requests originate from Cloudflares global network, but you cannot configure per-request IP rotation. All rendering traffic comes from Cloudflare IP ranges and requests include special headers [(`cf-biso-request-id`, `cf-biso-devtools`)](/browser-rendering/reference/automatic-request-headers/) so origin servers can identify them.
