Errand: open-source Grok Bot / Muse-style desktop (Runta)
开源桌面壳：每人一台云电脑，用来对照 Grok Bot。 Open-source desk where each teammate gets a cloud computer beside Grok Bot.
Apache-2.0 桌面壳 Errand（runerrand.dev）：每个队友一台 Runta 云电脑（shell / 浏览器 / 文件）。用来对照 Grok Bot「每席一电脑」，不是官方替代品。 Apache-2.0 desktop shell Errand (runerrand.dev): each teammate gets a Runta cloud computer (shell / browser / files). Listed beside Grok Bot’s per-seat computer — not an official replacement.
Errand 是开源 macOS 桌面客户端，许可证 Apache-2.0（仓库 LICENSE；GitHub license API 于 2026-09-23 仍为 Apache-2.0）。官网写明由 Runta Cloud Agents 驱动：每个队友有自己的对话，以及一台带着文件和工具的云电脑。关掉本地 App 不会删掉队友、对话或文件——App 只是看云端工作区的窗口。作者 Shiqi Mei 的 2026-09-22 长文，以及 HN item 49803044 的标题，把它说成 Grok Bot / Muse 的开源相邻做法。本站按这个口径收录：可复现的相邻栈，不是官方 Grok Bot 或 Muse 的替代品。 Errand is an open-source macOS desktop client under Apache-2.0 (repo LICENSE; the GitHub license API still reported Apache-2.0 on 2026-09-23). The site says it is powered by Runta Cloud Agents: each teammate has a conversation and a cloud computer with files and tools. Closing the local app does not delete teammates, conversations, or files — the app is a window onto the cloud workspace. Shiqi Mei’s 2026-09-22 write-up, and the title of HN item 49803044, frame it as an open-source take on Grok Bot / Muse. This library lists it on that basis: a reproducible adjacent stack, not an official Grok Bot or Muse replacement.
为什么推荐Why we recommend it Apache-2.0（GitHub license API，2026-09-23）。预览裁自长文界面图 conversation-and-computer.webp，3:2 自托管。依赖 Runta；不当官方替代品。 Apache-2.0 (GitHub license API, 2026-09-23). Depends on Runta; not marketed as an official replacement.
已对照 HN item 49803044、仓库 README、官网 FAQ 与作者 2026-09-22 长文。Checked against HN item 49803044, the repo README, the site FAQ, and the author’s 2026-09-22 write-up. Preview is the write-up UI image conversation-and-computer.webp, cropped to 3:2 and self-hosted.
左列是 Errand 在长文、仓库和官网上对得上的事实。右列只说明它为什么被拿来对照 Grok Bot「每席一电脑」，不补写本库没核过的官方操作。 The left column is what the write-up, repo, and site actually say about Errand. The right column only says why it sits next to Grok Bot’s per-seat computer — it does not fill in official behavior this library has not checked.

每个队友一台 Runta runtime：独立的 shell、浏览器和文件系统，跨任务还在。作者写明这台电脑在云上，点按发生在 runtime 里，不在你的笔记本上。 Each teammate gets a Runta runtime: its own shell, browser, and filesystem that stick around between tasks. The write-up says that computer is in the cloud — clicks happen on the runtime, not on your laptop.

同一类问题：一席一台电脑。这里不比较 Grok Bot 的具体实现。 Same class of idea: one computer per seat. This row does not compare Grok Bot’s implementation.

执行在 Runta，Errand 是客户端。退出 App 不会停掉正在跑的任务；再打开时按对话拉回 runs 和产物。官网 FAQ：关掉 App 不会删除队友、对话或文件。 Execution lives on Runta; Errand is the client. Quitting the app does not stop a run in progress; reopening fetches runs and artifacts per conversation. The site FAQ says closing the app does not delete teammates, conversations, or files.
对照 Grok Bot「每席一电脑」 Beside Grok Bot’s per-seat computer
用来对照「交办之后可以离开」。官方 Grok Bot 是否同样离开，以 xAI 文档为准。 Useful as a comparison for handing work off and leaving. Whether official Grok Bot behaves the same way is a question for the xAI docs.

可以从 Errand 打开队友的屏幕。作者写这是连到 runtime 的 VNC，用 noVNC 画在界面里，可以看，也可以接管。2026-09-23 仓库里 src/ui/components/VncDesktop.tsx 为 72 行，与长文一致。 You can open a teammate’s screen from Errand. The author describes a VNC session to the runtime, drawn with noVNC, for watching or taking over. On 2026-09-23, src/ui/components/VncDesktop.tsx in the repo is 72 lines, matching the write-up.
对照 Grok Bot「每席一电脑」 Beside Grok Bot’s per-seat computer
只记录 Errand 怎么看云桌面，不把这套 VNC 说成 Grok Bot 的做法。 This records how Errand shows the cloud desktop. It does not claim Grok Bot uses this VNC path.

作者称桌面大约 4,000 行 TypeScript，因为 runtime、computer-use、agent loop 和持久化已经在 Runta，所以一个人大约一周做出壳。本库没有重数整个仓库的行数。 The author says the desktop app is about 4,000 lines of TypeScript, because the runtime, computer-use, agent loop, and persistence already lived in Runta — so one person shipped the shell in about a week. This library did not re-count the repo.
对照 Grok Bot「每席一电脑」 Beside Grok Bot’s per-seat computer
对照的是「专席电脑 + 可离开」可以落在一层薄客户端上，前提是 runtime 已经存在。不是从零复刻的官方产品。 The comparison is that a per-seat computer you can leave can sit on a thin client when the runtime already exists. It is not a from-scratch official product.
先看 runerrand.dev 上的产品说明。页面里的对话是示例，不连接真实 Agent，也不会把消息发出去。系统要求以 FAQ 当日文字为准：Apple Silicon、macOS 13+、Runta 账号，以及为 Agent 配好的模型。 Start with the product page on runerrand.dev. The conversations on that page are samples: they do not connect to a real agent or send messages out. System requirements follow the FAQ as written that day: Apple Silicon, macOS 13+, a Runta account, and a model configured for the agents.
仓库是 runta-dev/errand，Apache-2.0。README 的 Quick start 是 clone 之后 npm ci、npm run dev（macOS 13+、Apple Silicon、Node.js 22–26）。本地桌面仍连接 Runta Cloud Agents，需要 Runta 账号和模型权限。 The repo is runta-dev/errand, Apache-2.0. The README quick start is clone, then npm ci and npm run dev (macOS 13+, Apple Silicon, Node.js 22–26). The local desktop still connects to Runta Cloud Agents, so you need a Runta account and model access.
HN item 49803044（2026-09-22）的标题把 Errand 称为一周做出的开源 Grok Bot / Muse alternative。Shiqi Mei 的长文解释壳为什么薄、关 App 为什么不停，并附有真实界面截图。 HN item 49803044 (2026-09-22) titles Errand as an open-source Grok Bot / Muse alternative built in a week. Shiqi Mei’s write-up explains why the shell is thin, why quitting the app does not stop the work, and includes real UI screenshots.
