Release v1.0.5. Install with one `kubectl apply` of the release manifest. Core `Sandbox` CRD handles lifecycle (create, scheduled delete, pause, resume) with persistent storage; extensions add `SandboxTemplate`, `SandboxClaim`, and `SandboxWarmPool` for pre-warmed allocation. Upstream Kubernetes project, not a vendor SaaS. ★~4.2k.","theCatch":"It schedules and manages sandboxes; it does not isolate them. Isolation comes from the RuntimeClass you pair it with — gVisor (see the gvisor gem) or Kata Containers — and without one you just have ordinary pods. Assumes you already run and operate a Kubernetes cluster. Vs e2b (hosted sandbox API with an SDK): Agent Sandbox is the self-hosted orchestration layer on your own cluster, with no hosted control plane.","verdict":"Apache-2.0 sandbox orchestrator for Kubernetes when agent runtimes need stable, warm, stateful pods — pair it with gVisor or Kata for the actual isolation.","addedAt":"2026-10-08","featured":false,"domain":"AI Agents","subSpecialty":"Sandbox","subcategory":"Sandbox","tags":["self-host","permissive","sandbox","kubernetes","active"],"capabilities":["kubernetes","sandbox","crd"],"surfaces":["Self-host","Hosted"],"ecosystem":["Go","Multi-platform"],"licenseModel":"Apache-2.0","githubStars":4307,"starsPerWeek":70,"access":"free","archived":false,"repo":{"createdAt":"2025-08-12","pushedAt":"2026-10-18","license":"Apache-2.0","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/agent-sandbox","html":"/gems/agent-sandbox","markdown":"/gems/agent-sandbox.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
