How to Run Browser Automation at Scale in the Cloud (2026)

This guide describes a queue-and-worker architecture for cloud browser automation, where each job gets its own isolated remote browser driven over CDP with Playwright or Puppeteer, with concurrency capped at the plan limit and browsers always stopped when jobs end. It compares pricing, concurrency limits and session caps across seven providers (Browser Use, Browserbase, Steel, Hyperbrowser, Browserless, Kernel, Anchor), works through a cost example of 1,000 jobs a day, and covers rate limits, retries with backoff, and self-hosting versus managed trade-offs.
