Cube SandboxEmpowering your AI Agents.

Instant, Concurrent, Secure & Lightweight Sandbox for AI Agents.

⚡ Ultra-fast Startup

Resource pooling and snapshot cloning skip all cold-start overhead. Sandbox creation faster than a blink.

Every sandbox runs a dedicated OS kernel in its own MicroVM.

Drop-in replacement for E2B Cloud. Switch by changing one environment variable — zero client code changes.

MB-level per-sandbox overhead enables thousands of instances per server via kernel sharing and Copy-on-Write.

eBPF-based CubeVS enforces strict inter-sandbox isolation and fine-grained egress filtering at the kernel level.

Checkpoint, restore, and fork sandbox states for parallel development and multi-version testing. (Coming soon)
