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 and microsandbox give you isolated code execution—but that’s it. You still need to build:

You build With sandbox-only With Tako VM

Job queue Redis + Celery/Bull Built-in

Execution history Postgres + schema PostgreSQL included

Retry logic Custom code Automatic

Idempotency Deduplication logic idempotency_key

Replay/debugging Custom tooling Rerun/fork API

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
