Sanbox, Aether, and Code Airlock launch MicroVM isolation platforms for coding agents

Sanbox, Aether, and Code Airlock have launched orchestration platforms providing isolated microVM execution, persistent filesystems, and resumable state for Claude Code and Codex agents. Sanbox offers per-second metering and parallel runs with snapshot resumption; Aether adds Slack and Linear integrations with scheduled automations; Code Airlock wraps Docker sandboxes to let agents work unattended while committing results as reviewable git commits. All three record tool calls, model activity, and agent session metadata for auditability.
