Hardware-level isolation, pause/resume, K8s deploy path, volume plugins, and template aliases. Aimed at concurrent agent workloads, not a single toy container.","theCatch":"Vs E2B, Daytona, and Cloudflare Sandbox: this is a self-hosted RustVMM/KVM sandbox control plane, not a hosted sandbox SaaS, a workspace platform, or an edge isolate runtime. GitHub license detect shows NOASSERTION even though LICENSE is Apache-2.0 — verify the tree before compliance sign-off (a detection caveat). Linux + KVM on x86_64 (ARM64 maturing); ops weight is real.","verdict":"Apache KVM sandbox when you need dense, E2B-shaped isolation on your own Linux hosts; confirm license text and hardware before betting the fleet.","addedAt":"2026-09-24","featured":false,"domain":"AI Agents","subSpecialty":"Orchestration","subcategory":"Orchestration","tags":["api","self-host","permissive","license-unclear","sandbox","active"],"capabilities":["sandbox","kvm","agents"],"surfaces":["API","Self-host"],"ecosystem":["Rust","Multi-platform"],"licenseModel":"Apache-2.0","githubStars":12976,"starsPerWeek":472,"access":"free","archived":false,"repo":{"createdAt":"2026-04-10","pushedAt":"2026-10-19","license":"NOASSERTION","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/cubesandbox","html":"/gems/cubesandbox","markdown":"/gems/cubesandbox.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
