agent-sandboxKubernetes SIG Apps' Sandbox CRD and controller: stateful singleton pods with stable identity and persistent storage for agent runtimes and RL — templates, claims, warm pools; gVisor/Kata isolation.
Why switchBoth give agents managed sandboxes on Kubernetes. OpenSandbox is a full platform (multi-language SDKs, CLI, MCP, Docker too); agent-sandbox is the minimal upstream CRD you compose yourself.
Full comparison → CubeSandboxHardware-isolated microVM sandboxes for AI agents — sub-60ms boot, <5MB overhead, E2B-compatible API, self-hosted on your own KVM nodes.
Why switchBoth self-hosted sandbox runtimes for agents, split by isolation bet: CubeSandbox is microVM-first (KVM boundary, E2B-compatible API); OpenSandbox is platform-first (Docker/K8s runtimes, SDKs, CLI, MCP) for teams standardizing on existing infra.
Full comparison → ephemora-cellCapability-based WASM sandbox for MCP tools and agent-generated code: wasmtime + WASI with fuel, memory, time and I/O caps per run, sub-ms warm execution and signed (JCS/ES256) execution records.
Why switchopensandbox exposes sandboxes over Docker/K8s via SDKs and MCP; Cell is the in-process WASM alternative when you don't need a whole OS per execution.
Full comparison → computerVirtual filesystem for agents inside a Cloudflare Durable Object — SQLite-authoritative state with pluggable execution: FUSE-mounted containers, isolate shell (just-bash) or isolate JavaScript.
Why switchSandboxed execution for agents: OpenSandbox provisions Docker/K8s runtimes behind a unified API; computer gets the same job done with Durable Objects and Workers isolates.
Full comparison → OpenShellNVIDIA's safe runtime for autonomous agents: kernel-enforced sandboxes with policy on every file, syscall and connection; credentials injected only for approved endpoints.
Why switchBoth give agents isolated sandboxes over Docker/Kubernetes with SDKs and a CLI; OpenSandbox centers on a unified sandbox API, OpenShell on per-agent policy enforcement and credential brokering.
Full comparison → arcboxOpen-source container and VM runtime for macOS in pure Rust: drop-in Docker engine, sub-100ms agent sandboxes (`abctl claude`), full Linux VMs and throwaway macOS guests on one daemon.
Why switchOpenSandbox is a sandbox platform — SDKs, API, MCP — over Docker or Kubernetes; ArcBox is the runtime underneath that class of thing on a Mac, with the sandbox exposed directly through abctl.
Full comparison → axGoogle's declarative runtime for agent workloads on Kubernetes: Task, Workspace and Model manifests run each agent sandboxed on Agent Substrate, with suspend/resume and ax ssh.
Why switchBoth run agent workloads in managed sandboxes on Kubernetes; OpenSandbox is a platform with SDKs, CLI and MCP that also runs on Docker, AX is a declarative orchestrator aimed at cluster-scale fleets.
Full comparison → cuaComputer-use infrastructure for agents: sandboxed Linux, macOS and Windows desktops locally or in the cloud, Cua Driver for native apps (CLI/MCP/SDK), Lume VMs, CUA-S1 models, Cua Bench.
Why switchBoth provide sandboxes for GUI agents; OpenSandbox spans coding, GUI and eval workloads over Docker and Kubernetes, Cua centres on full desktops with input, video and a native-app driver.
