Sandboxer vs Browser Use (cloud)

Browser Use cloud is a pay-as-you-go hosted browser service for AI agents, listed at $0.02 per browser hour plus proxy bandwidth. Sandboxer is a different category: each sandbox is a full Ubuntu VM with root, Docker and nested KVM, not a browser instance. Pick Browser Use for web automation; pick Sandboxer when the agent needs a whole machine.

Where Browser Use (cloud) is strong

  • Very low listed browser rate of $0.02 per hour.
  • No subscription; credits never expire and new users get $1 free.
  • Concurrency scales with total paid, from 10 sessions up to 1,000.
  • Open-source library available for self-running agents.

Where Sandboxer differs

  • Browser Use provides browsers, not Linux machines with root, Docker or KVM.
  • Residential proxies are on by default and billed per GB on top of browser time.
  • Sandboxer sessions can run with no time limit on a paid plan; Browser Use's maximum session length is not stated on its pricing page.

Pick Browser Use (cloud) if

  • You are automating websites with an agent and want the cheapest browser hour.
  • You want pay-as-you-go credits with no monthly plan.
  • You want to use the open-source Browser Use library with a hosted backend.

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.
