Browser Run

Browser Run (formerly Browser Rendering) gives Workers a Puppeteer/Playwright-compatible binding to headless browsers running on Cloudflare’s network. Screenshots, PDF generation, scraping, automated testing of rendered pages — all without owning the miserable job of running a Chrome fleet.

Anyone who has operated headless browsers at scale knows they’re the worst kind of infrastructure: memory-hungry, crash-prone, endlessly needing updates. Outsourcing that for a per-use price is easy to justify, and the binding integration means the browser is right next to your existing Workers logic.

Deducted points for concurrency and session-duration limits that bite at scale, occasional version-drift surprises between the managed browsers and what your scripts expect, and costs that deserve a spreadsheet before you commit a heavy workload. For low-to-moderate volume automation, it’s a clear win.
