## What it is
Microsandbox is a local-first microVM runtime and library for running untrusted workloads (AI agents, user code, plugins, CI jobs) inside fast, hardware-isolated lightweight VMs. It offers Docker-like OCI image workflows, sub-100ms startup, multi-language SDKs (TypeScript, Rust, Python, Go, Ruby), an MCP server, and optional hosted cloud execution.

## Use cases
- run untrusted AI agent code in an isolated sandbox
- execute user-submitted code safely on my server
- sandbox CI jobs and package installs
- run scrapers and automation in isolated microVMs
- give coding agents a sandboxed execution environment via MCP
- spin up ephemeral dev environments from application code
- run docker images with hardware-level isolation locally

## When to choose
- you need stronger isolation than containers for untrusted or AI-generated code
- you want Docker-like OCI workflows with VM-level security boundaries
- you need fast, programmatically spawned sandboxes with no daemon
- you want agents to self-manage sandboxes via MCP or skills

## When to avoid
- you only need lightweight process-level sandboxing and KVM/WHP virtualization is unavailable
- you need orchestration at scale across a cluster rather than local-first sandboxes
- your workloads are fully trusted and plain containers suffice

## Facets
- artifact type: library
