Browser Run: Browser Rendering renamed with higher limits and new observability features
Key Points
- Browser Rendering renamed to Browser Run
- 4× concurrency increase for Workers Paid
- Live View, human-in-the-loop, session recordings
Summary
Cloudflare renamed "Browser Rendering" to "Browser Run" and shipped a dashboard redesign, higher Workers Paid limits, and new observability and agent features. Browser Run runs full browser sessions on Cloudflare's network, driven by code or AI, with recording/replay, crawling, debugging, and human intervention.
Key Points
- Rename: Browser Rendering → Browser Run (branding only; APIs and functionality continue to work).
- Increased limits for Workers Paid plans:
- Concurrent browsers per account: 30 → 120
- New browser instances: 30 per minute → 1 per second
- REST API rate limits: 3 → 10 requests per second
- All rate limits are now expressed and enforced as per-second values.
- Dashboard: single "Runs" view shows every request (sessions, screenshots, PDFs, crawls), with filtering by endpoint, URL, status, duration, and expandable rows for details.
- New features useful for engineers:
- Live View: observe agent/browser activity in real time for faster debugging.
- Human in the Loop: allow manual intervention when automation needs help.
- Session Recordings: record and replay full sessions for troubleshooting and testing.
- WebMCP: structured website tools for AI agents to discover and call directly, reducing brittle screenshot-and-parse loops.
- No action required to receive higher limits; plan capacity accordingly if you relied on previous limits.
Practical notes
- Update internal docs and alerts to reference "Browser Run" where applicable.
- Review automation and retry logic against the new per-second rate limits and increased concurrency.
- Use Live View and Session Recordings to speed debugging and root-cause analysis.
