Where Hyperbrowser is strong

  • Entry price of $30/month for 25 concurrent sessions.
  • Free plan with 5,000 credits.
  • Enterprise tier with 1,000+ concurrent sessions and 180+ days retention.
  • Simple credit model for browser hours.

Where Sandboxer differs

  • Hyperbrowser offers browsers, not VMs with root, Docker or KVM.
  • Session length and regions are not on its pricing page.
  • Plans are credit-based; Sandboxer plans set concurrency and return every dollar as machine time.

Pick Hyperbrowser if

  • You need many cheap concurrent browser sessions.
  • You want a low-cost monthly plan with a free tier.
  • Your workload is web automation only.

Pick Sandboxer if

  • You need a full Ubuntu 24.04 VM with root, systemd, Docker and nested KVM rather than a browser only.
  • You want stop/resume that brings running processes back, and sandboxes that cost nothing while stopped.
  • You want coding agents (Claude Code, Codex and others) preinstalled and any port exposed as an HTTPS URL.
