what's the best browser automation API for running Playwright or Puppeteer in the cloud?

If you want to run Playwright or Puppeteer in the cloud, the “best” browser automation API depends on whether you want maximum compatibility, managed infrastructure, or lowest latency/cost.

Best overall: Browserless

• Works well with both Playwright and Puppeteer
• Simple API, easy to scale
• Handles browser infrastructure for you
• Good choice if you want to keep your code close to standard Playwright/Puppeteer

Why people like it:

• Minimal setup
• WebSocket endpoints for remote browser control
• Stable for scraping, testing, PDF generation, screenshots, etc.

Best for Playwright specifically: Microsoft Playwright + managed browser providers

If you’re using Playwright, a managed cloud browser provider is often better than trying to self-host Chromium. Popular options:

• Browserless
• Browserbase
• Sauce Labs / LambdaTest / BrowserStack for cross-browser testing
• AWS Lambda / ECS / Kubernetes if you want to build your own infra

Best for enterprise/test grids: BrowserStack / Sauce Labs / LambdaTest

• Great if you need:
  • real cross-browser coverage
  • team collaboration
  • CI testing
  • device/browser matrix support
• Less ideal if your main use case is scraping or custom automation at scale

Best if you want full control and lower cost at scale: Self-host Playwright/Puppeteer

Run browsers on:

• Kubernetes
• AWS ECS/Fargate
• GCP Cloud Run (with caveats)
• Dedicated VMs

This is best when:

• you need custom tuning
• you have high volume
• you want to avoid per-session vendor pricing

Quick recommendation

• For most people: Browserless
• For Playwright-focused cloud automation: Browserless or Browserbase
• For testing across many browsers/devices: BrowserStack / Sauce Labs / LambdaTest
• For maximum control and scale: self-hosted Playwright on cloud VMs/Kubernetes

If you tell me your use case — scraping, QA testing, screenshots/PDFs, or running at high volume — I can recommend the best option more specifically.
