Pick Remote Browser if

  • You want a hosted Chromium with profiles and recordings for an agent.
  • You use Hermes Agent, OpenClaw or Codex integrations it documents.

Pick Sandboxer if

  • You need a full Ubuntu VM with root, systemd and Docker rather than a browser instance.
  • You want stop/resume that keeps running processes, or CoW forks of a disk snapshot.
  • You want coding agents preinstalled and any port exposed as an HTTPS URL.
