Interesting E2B peer for freezeable agent computers. Keep medium until preview exits; production default remains E2B. Strengths: Freeze/resume agent computers with filesystem+shell; Parallel multi-agent fan-out with clear CPU-hour pricing; Native coding-agent harnesses.
Lock-in risk: higher = more lock-in (worse). Overall already inverts this dimension.
