# Claude Code sandbox

16 Hacker News commenters recommended Claude Code sandbox and 18 criticized it, November 2025 to November 2026. It was recommended in 6 of 13 months.

**Verdict:** Sandbox built into Claude Code that cuts down permission prompts for commands. Critics say it gives read access to everything and is disabled by default.
