Ephemeral Sandbox is open-source agent-sandbox infrastructure for teams running multiple coding agents safely against one codebase. Instead of giving every agent access to the same writable checkout, it creates a private copy-on-write workspace session for each agent over a shared, immutable LayerStack. Commands run inside a holder-owned Linux namespace, so the session's filesystem and process boundary persist across operations. When work is ready, Ephemeral Sandbox compares the session with the latest shared head, resolves changes path by path, and publishes one atomic layer, or publishes nothing if the change set cannot be accepted.
Operators can inspect commands, file activity, resource use, and line provenance through dedicated CLI, MCP, and observability interfaces. The system is designed for local and Docker-backed multi-agent workflows that need parallel execution with isolation, auditability, and a defined promotion path.

No known CVEs for Ephemeral Sandbox.
Coverage is best-effort and depends on a winget package mapping to an NVD CPE entry. Absence here is not a guarantee of safety.
