Zeroboot is an open-source sandboxing service that spawns sub-millisecond KVM virtual machines for AI agent code execution by forking Firecracker snapshots via copy-on-write memory mapping. It exposes an HTTP API and Python/TypeScript SDKs, and can be self-hosted on any Linux host with KVM or used via a managed API.

Use cases

• run untrusted AI-generated code in isolated VMs
• spawn thousands of sandboxes with millisecond latency
• execute Python or JavaScript snippets server-side for agents
• self-host a code execution sandbox on a Linux box with KVM
• replace E2B or Daytona with a faster, cheaper sandbox
• give LLM agents a safe compute environment with hardware isolation

When to choose

• you need hardware-enforced VM isolation for untrusted agent code
• spawn latency and per-sandbox memory footprint are critical
• you want an open-source, self-hostable alternative to E2B or microsandbox
• you run Linux hosts with KVM support

When to avoid

• you need a production-hardened, battle-tested sandbox today
• your hosts lack KVM or you run on macOS/Windows
• you need non-Linux guest runtimes beyond the preloaded templates
• you require long-lived persistent sandboxes rather than short-lived forks
