Comprehensive analysis of Sanbox's strengths and weaknesses based on real user feedback and expert evaluation.
Kernel-level MicroVM isolation is a real boundary, not shared-kernel containerization
Snapshots make agent runs pausable and resumable from the exact state — inspectable mid-run
EU data residency, on-prem, and VPC deployment options cover compliance-sensitive teams
Live structured event stream removes the need to poll for run status
Reusable run templates pin the approved image, model, limits, and egress policy in one place
5 major strengths make Sanbox stand out in the agent-infrastructure category.
Pricing is not published — access requires a signup and likely sales conversation
No MCP support currently — integration is CLI, template, and run-based only
Newer entrant; smaller ecosystem than E2B, Modal, or Daytona in adapters and community examples
Documentation on runner adapter contracts is thin outside the OpenCode reference
CLI-first workflow may feel heavier than one-line SDK calls for quick prototyping
5 areas for improvement that potential users should consider.
