Tako VM
Serverless file systems for agents
Last checked:
What is Tako VM?
Tako VM is a secure Python execution sandbox designed for AI agents to run untrusted, often AI-generated code in isolated gVisor containers. It provides built-in job queuing, execution history, retries, and replay capabilities, eliminating the need to build these systems manually.

Tako VM pros
- Built-in job queue, execution history, and retry logic (no Redis/Celery setup required)
- Strong isolation via gVisor userspace kernel with seccomp filtering and default-deny network
- Replay and debugging capabilities to rerun past jobs with identical inputs
- Self-hosted with zero per-execution cost and offline capability; integrates with LangChain and OpenAI tool-calling
Tako VM cons
- Requires Docker and gVisor setup; not a serverless solution
- Limited to Python code execution
- Self-hosted deployment adds operational overhead compared to managed alternatives
Frequently asked questions about Tako VM
How is Tako VM different from other sandbox tools like e2b?
Sandbox-only tools provide isolation but require you to build job queuing, execution history, retries, and replay yourself. Tako VM includes all of these built-in, plus idempotency support.
What security measures does Tako VM use?
Each job runs in its own ephemeral Docker container behind gVisor's userspace kernel with seccomp filtering, dropped capabilities, non-root user, and no network access by default. Production deployments can enable strict mode to fail rather than fallback to standard runc.
Can I integrate Tako VM with AI agents?
Yes. Tako VM provides agent integration guides for LangChain and OpenAI tool-calling, allowing agents to safely execute code via the REST API or Python SDK.
