View guide →Open Cowork: a desktop AI agent app with one-click Claude Code, MCP tools, skills, and VM sandboxing.
open-cowork is an open-source ai agents project by OpenCoworkAI (OpenCoworkAI/open-cowork on GitHub). It has 2,195 GitHub stars and 310 forks, is released under the MIT license, and was last updated on GitHub on 6 October 2026.
Decide which workspace folder the agent may work in, and which model provider you will connect.
Install the app via Homebrew on macOS, the downloadable installer, or build it from source.
Open Settings, paste your API key, and set the provider base URL and model name exactly as the provider table specifies.
Select a workspace folder and give the agent a task, such as summarising a spreadsheet into a presentation, and watch its work in the trace panel.
Pre-built Windows and macOS installers need no environment setup, and the chat interface supports drag-and-drop files and images.
Works with Claude, OpenAI-compatible APIs, and providers such as GLM, MiniMax, and Kimi, including through OpenRouter, with flexible base-URL configuration.
Commands run in WSL2 on Windows or a Lima VM on macOS when available, with a path-guard fallback that confines file operations to the chosen workspace.
Bundled skills generate and process PPTX, DOCX, XLSX, and PDF files, and users can create custom skills.
Connects to browsers, Notion, and other desktop apps through MCP, and can operate desktop GUIs directly via computer use.
Feishu (Lark) and Slack integration let you direct the agent remotely, while the trace panel shows reasoning and tool calls in real time.
End users can skip this and use the Homebrew cask or installer instead.

Yes, the app is MIT-licensed and free. You pay only your chosen model provider for API usage.
Yes: the agent is powered by your own API key from a supported provider such as Anthropic, OpenRouter, Zhipu (GLM), MiniMax, or Kimi.
Claude Cowork is Anthropic's closed product; Open Cowork is an open-source implementation that adds GUI operation and remote control alongside MCP and skills support, per its own comparison table.
Install via Homebrew (brew install --cask open-cowork after tapping OpenCoworkAI/tap) or the release installer, add your API key in Settings, choose a workspace, and prompt.
