PricingFree (open-source local runtime, no paid tiers)Freemium (Cloud: free tier up to certain actions, then usage-based; self-hosted: open-source free)
Core Use CaseHardware-isolated local sandboxes for untrusted code execution (AI agents, CI/CD)Reliable orchestration of long-running, fault-tolerant workflows (AI agents, microservices)
Deployment ModelLocal (no daemon, no remote service; single-machine)Cloud or self-hosted (distributed, stateful backend)
Isolation LevelHardware-isolated microVM (separate kernel per sandbox)Process-level (workflow workers); no sandboxing per se
State & DurabilityEphemeral sandboxes; state not preserved across sandbox restartsFull state persistence and recovery via event sourcing; survives crashes
Target UsersSecurity-conscious developers running untrusted user code locallyDevOps, platform teams, AI engineers building reliable distributed systems

For teams needing reliable, crash-proof orchestration of long-running workflows with built-in retries and human-in-the-loop, Temporal is the clear choice. Microsandbox excels when you need to run untrusted code in a hardware-isolated local sandbox with minimal overhead. They solve different problems, but if you need both, they can complement each other: use Temporal to orchestrate steps that run in Microsandbox sandboxes.

Who should pick which

  • AI Agent Developer
    Pick: Temporal AI

    Temporal provides durable execution, retries, and visibility for complex agent workflows, while Microsandbox can run isolated code executions—but the orchestration layer needs Temporal's reliability.

  • Platform Engineer (user code isolation)
    Pick: Microsandbox

    Microsandbox's hardware-isolated microVMs are perfect for running untrusted user code locally or in CI with strong security guarantees, no orchestration overhead.

  • DevOps Engineer (CI/CD builds)
    Pick: Microsandbox

    Microsandbox isolates build jobs in separate microVMs without a daemon, ideal for reproducible CI pipelines with low latency and zero cost.

  • Financial Systems Architect (Saga transactions)
    Pick: Temporal AI

    Temporal's built-in Saga pattern support and durable state ensure compensating transactions complete reliably across failures.

  • Startup building AI agents
    Pick: Temporal AI

    Temporal's free tier and integrations with OpenAI and Google ADK make it easy to start building reliable AI agent workflows with minimal cost.

Frequently Asked Questions

Microsandbox vs Temporal AI: which should you choose?

For teams needing reliable, crash-proof orchestration of long-running workflows with built-in retries and human-in-the-loop, Temporal is the clear choice. Microsandbox excels when you need to run untrusted code in a hardware-isolated local sandbox with minimal overhead. They solve different problems, but if you need both, they can complement each other: use Temporal to orchestrate steps that run in Microsandbox sandboxes.

Can I use Temporal to orchestrate Microsandbox sandboxes?

Yes, Temporal's Activities can invoke Microsandbox's CLI or SDK to launch sandboxes, combining durable orchestration with hardware isolation.

Does Microsandbox provide any state persistence?

No, Microsandbox sandboxes are ephemeral. State can be stored externally (e.g., volumes) but there is no built-in workflow recovery like Temporal.

Which tool is better for running untrusted AI agent code?

Microsandbox for isolation (hardware-level), Temporal for orchestration (reliability). Use Microsandbox to sandbox individual code executions and Temporal to orchestrate the overall agent workflow.

Is Microsandbox cloud-managed?

No, Microsandbox is a local runtime only. There is no cloud service; it runs on your machine as a CLI tool or via SDK.

Does Temporal support Windows?

Temporal SDKs support multiple languages (Java, Go, etc.) that run on Windows, but the Temporal server typically runs on Linux. Microsandbox v0.6.0 added Windows host support.

Can I use Temporal for low-latency request-response?

No, Temporal is designed for durable, long-running workflows; it adds overhead that is unsuitable for synchronous, low-latency APIs.

What is the learning curve for each tool?

Temporal requires understanding workflow-as-code, state persistence, and temporal concepts (Tasks, Activities, Workers). Microsandbox is simpler: CLI-based with familiar Docker-like commands.

Which tool has better community support?

Temporal has a large community, many integrations (OpenAI, Slack, etc.), and is used by major companies. Microsandbox is newer and smaller, but active on GitHub.
