What changed
Cloudflare raised Browser Run Workers Paid defaults to 200 concurrent browsers, 3 new instances per second, and 30 Quick Actions requests per second.

Higher concurrency makes it more practical to run browser automation and agent workloads such as screenshots, PDFs, and interactive sessions at scale on Cloudflare's network without requesting custom quotas.
