tako-vm 0.3.0

File system and python execution for your agents. Job queues and Docker isolation built-in. Used by teams deploying in enterprise.

English | 日本語

A secure file system for your agents to execute code. Every job runs in its own isolated Docker container, with an ephemeral workspace, optional gVisor sandboxing, job queues, retries, and execution history included.

Where this is headed: durable, per-agent workspaces that persist and rehydrate across runs, a serverless filesystem for agents. Today each container is single-use; persistent workspaces are on the roadmap. gVisor remains the sole isolation boundary.

# Install (requires Docker + Python 3.10+)
pip install "tako-vm[server]"
tako-vm setup                   # pull the executor Docker image
tako-vm server                  # start server (auto-starts PostgreSQL via Docker)

# Execute code
curl -X POST http://localhost:8000/execute \
  -H "Content-Type: application/json" \
  -d '{"code": "print(1 + 1)"}'

Why Tako VM?

Sandbox solutions like e2b, daytona and microsandbox give you isolated code execution, but that's it. You still need to build:

Tako VM is the complete package:

• Job queue + workers - Async execution with worker pool, no Redis/Celery setup
• Execution history - Every job persisted with stdout, stderr, timing, artifacts
• Replay to debug - Rerun past jobs with exact same code and inputs
• Docker isolation - Each job in its own container with seccomp filtering
• Network isolation - No network by default, optional allowlist per job type
• Self-hosted - Your machine, offline-capable, zero per-execution cost

CLI

tako-vm setup                     # Pull executor image and verify Docker
tako-vm server                    # Start the API server
tako-vm server --port 9000        # Custom port
tako-vm dev up                    # Start local PostgreSQL for development
tako-vm dev up --with-server      # Start PostgreSQL + API server
tako-vm dev status                # Check local PostgreSQL status
tako-vm dev down                  # Stop local PostgreSQL
tako-vm config                    # Show current configuration
tako-vm config --json             # Output as JSON
tako-vm validate                  # Validate current config
tako-vm validate my.yaml          # Validate specific file
tako-vm status                    # Check server health
tako-vm version                   # Show version
tako-vm --config my.yaml server   # Use specific config file

Security

Tako VM runs untrusted, often AI-generated, code, so isolation is the core of the project. It uses layered defenses: gVisor (userspace kernel), per-job ephemeral Docker containers, a default-deny seccomp profile, network isolation (--network=none by default), capability dropping, non-root execution, and enforced resource and input limits.

security_mode: strict with container_runtime: runsc is the default: Tako VM refuses to start a job rather than run it without the gVisor userspace-kernel boundary. Set security_mode: permissive to allow a fallback to standard Docker (runc) on hosts without gVisor, e.g. local development or CI; that fallback removes the userspace-kernel boundary, so do not use it for untrusted code.

See SECURITY.md for the threat model and hardening guidance, and docs/deployment/security.md for full details.
