Temporal AI and Greywall solve entirely different problems — one is a durable execution platform for orchestrating resilient server-side workflows, the other a lightweight sandbox for securing local AI coding agents. If you need crash-proof, long-running orchestration with retries and human-in-the-loop, Temporal is the clear choice. If you're a developer running Claude Code or similar CLI agents and want to prevent them from reading your .env files or reaching unknown networks, Greywall's free, zero-config sandbox is exactly what you need.

One-line install via Homebrew, curl, Go install, or build from source
Works with any local CLI agent with no agent-specific configuration
Linux and macOS support with graceful degradation on older kernels
Durable execution captures Workflow state at every step with no checkpointing or recovery code
Native SDKs for Go, Java, Python, TypeScript, .NET, PHP, Ruby, and Rust
Activities retry automatically with backoff, four timeout classes, and heartbeating
Signals, Queries, and Updates read and mutate running Workflows mid-flight
Workflow Streams for real-time interactivity with running executions
Durable AI agents via OpenAI Agents SDK and Google ADK running LLM and tool calls as Activities
Serverless Workers host durable AI agents on Amazon Bedrock AgentCore
Serverless Workers on AWS Lambda (public preview) and GCP Cloud Run (pre-release)
Standalone Activities as a durable job-queue pattern, GA across six SDKs (2026-09-15)
Native Task Queue priority and fair distribution without a custom queueing layer
Durable Timers sleep for months; cron Schedules support backfill and Continue-As-New
Saga pattern via compensating transactions that read like try/catch
Worker Versioning pins Workflows to a version so deploys don't corrupt in-flight runs
Cloud UI Strict Session Mode enforces 15-min inactivity timeout and 12-hour max session (GA 2026-09-18)
Replay tests validate against real histories; time-skipping tests fast-forward long timers in CI

What real users say: Greywall vs Temporal AI

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

Greywall

17 mentions across 2 sources · 78% positive (averaged across 2 sources)

Hacker News, GitHub

What users praise

  • • Kernel-level sandboxing provides stronger isolation than container or VM approaches.
  • • Deny-by-default policy prevents agents from accessing sensitive files like .env and SSH keys.
  • • Live activity feed shows every read, write, and network request in real time.
  • • Supports any CLI agent without modifications, including Claude Code, Codex, and Cursor.

What frustrates them

  • • Very early-stage with only ~250 GitHub stars and 22 open issues.
  • • A user reported it could be forkbombed by a compromised package, raising reliability doubts.
  • • Limited community presence outside Hacker News and GitHub makes support uncertain.
  • • No official documentation or tutorials beyond the GitHub repo and website.

Temporal AI

No verifiable community signal. We scanned public discussion on Oct 14, 2026 and found posts matching the name “Temporal AI”, but could not establish that they are about this product rather than something else sharing its name. Rather than publish a score built on the wrong subject, we publish none.

Who should pick which

  • Solo founder using Claude Code
    Pick: Greywall

    Greywall's free, kernel-enforced sandbox prevents accidental leakage of API keys and .env files without any container overhead or agent-specific config.

  • Engineering team building AI agent pipelines
    Pick: Temporal AI

    Temporal provides durable execution with automatic retries, state persistence, and human-in-the-loop, essential for reliable multi-step AI workflows.

  • Platform engineer evaluating security for agent tools
    Pick: Greywall

    Greywall offers fine-grained filesystem and network sandboxing with real-time activity feed, ideal for enforcing boundaries without disrupting developer workflow.

  • Fintech team implementing Saga transactions
    Pick: Temporal AI

    Temporal's native support for compensating transactions (Saga pattern) and automatic retries makes it the go-to for financial systems requiring rollback on failure.

  • Open-source contributor managing multiple agents
    Pick: Greywall

    Greywall integrates with any CLI agent (Aider, Goose, etc.) and its learning mode auto-generates permission templates, streamlining security for diverse tools.

Frequently Asked Questions

Greywall vs Temporal AI: which should you choose?

Temporal AI and Greywall solve entirely different problems — one is a durable execution platform for orchestrating resilient server-side workflows, the other a lightweight sandbox for securing local AI coding agents. If you need crash-proof, long-running orchestration with retries and human-in-the-loop, Temporal is the clear choice. If you're a developer running Claude Code or similar CLI agents and want to prevent them from reading your .env files or reaching unknown networks, Greywall's free, zero-config sandbox is exactly what you need.

Can I use Temporal to sandbox local coding agents?

No — Temporal is a server-side orchestration platform, not a local sandbox. For sandboxing coding agents, use Greywall.

Can Greywall orchestrate multi-step workflows?

No — Greywall is purely a security sandbox; it doesn't provide workflow orchestration or state persistence. Use Temporal for that.

Is Greywall a container or virtual machine?

No — it's a kernel-enforced sandbox using macOS Endpoint Security or Linux eBPF/Landlock/Seccomp, lighter than containers.

Does Temporal support human-in-the-loop workflows?

Yes — via signals and pause/resume, Temporal allows workflows to wait for human input before proceeding.

Is Greywall agent-specific?

No — it works transparently under any CLI agent (Claude Code, Codex, Cursor, Aider, etc.) without agent-specific configuration.

Can I run Temporal locally for free?

Yes — the open-source Temporal Server is free to self-host; only Temporal Cloud has usage-based billing.

Does Greywall block network calls?

Yes — it uses a TUN + SOCKS5 proxy to allow/deny network access per-rule.

Which is better for a solo developer?

Depends on the task: use Greywall to secure local coding agents; use Temporal for building resilient backend workflows (but it may be overkill for simple tasks).
