Story

Anthropic is building its own lightweight sandbox for Claude Code that doesn't require container overhead. Filesystem and network isolation without Docker. Three-tier sandboxing stack now available: Claude Code Sandbox Runtime (lightweight, no containers) → Docker Sandboxes (medium isolation) → full VM (maximum isolation). The competitive dynamic here is interesting — Anthropic doesn't want to depend on Docker for its agent security story. Anthropic Engineering
