## What it is
Gondolin is a TypeScript library and CLI that runs untrusted AI-agent code inside fast local Linux micro-VMs (QEMU by default, optional libkrun backend). Network egress and filesystem access are controlled programmatically from the host, with secrets injected only for allowed destinations to prevent exfiltration.

## Use cases
- sandbox AI agent generated code before running it
- run curl commands with secrets the guest can never see
- restrict which hosts a sandboxed process can reach
- snapshot and resume isolated dev sessions
- give agents a disposable Linux environment with controlled filesystem access
- prevent credential exfiltration from untrusted code

## When to choose
- you run LLM-generated code locally and need egress and secret protection
- you want programmable network/filesystem policy in JavaScript
- you need fast-booting micro-VMs on macOS or Linux without cloud sandboxes

## When to avoid
- you need production-grade, audited isolation guarantees
- you are not on macOS or Linux
- you need Windows sandboxing or GPU workloads inside the VM
