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
