Key Features
  • • Managed Chrome sessions accessible over CDP, Playwright, Puppeteer
  • • Automatic Cloudflare / hCaptcha solving
  • • Residential proxy rotation with per-country targeting
  • • Hardware-level security isolation
  • • Sub-150ms sandbox startup
  • • Multi-language runtime support

Kernel - Pros & Cons

Pros

  • ✓Eliminates the six-month infra project of running a production headless-Chrome pool
  • ✓Works with existing Playwright / Puppeteer code — no SDK lock-in
  • ✓Captcha + residential proxy handling meaningfully improves scraping success rates
  • ✓Replay UI is a huge productivity win for debugging agent trajectories
  • ✓Free hobby tier makes prototyping cheap

Cons

  • ✗Usage-based pricing scales with browser-minutes — long-running research agents can get expensive fast
  • ✗Managed service (no self-host) — regulated customers may need to wait for VPC deploy
  • ✗Newer than Browserbase and Steel; smaller community for Stack Overflow-style questions
  • ✗Captcha solving still probabilistic — some highly protected targets will fail

E2B - Pros & Cons

Pros

  • ✓Strong isolation via Firecracker — safe enough for fully LLM-generated code
  • ✓150ms cold-start is fast enough for interactive chat-style agents
  • ✓Drop-in ChatGPT-style Code Interpreter SDK with persistent Jupyter kernels
  • ✓Desktop sandbox makes browser-use and computer-use agents practical
  • ✓Production-proven (Perplexity, Hugging Face) and well-instrumented

Cons

  • ✗Per-hour pricing can balloon for long-running autonomous agents
  • ✗Pro tier only includes 20 hours/mo — most teams burn through it
  • ✗Smaller per-sandbox resource limits than running on your own GPU box
  • ✗No GPU access on standard sandboxes (use Modal or RunPod for that)
