Why people look for alternatives to E2B

The complaints that come up most often in public discussion — reviews, forums and community threads. Not our opinion, and not the vendor's marketing.

  • Cost can add up for high-volume or long-running sandboxes.
  • Sandbox resource limits may constrain heavy agent tasks.
  • Limited community presence outside Hacker News.
  • Pricing structure less transparent than some competitors.

In fairness: users also consistently praise quick sandbox spin-up in seconds via sdks or cli, and strong isolation with full linux vms per sandbox. A complaint list is not a verdict — see the full picture on the E2B page.
