Open Claude Cowork Reviews — Discover what people think of this product.

Open Claude Cowork is an open-source desktop chat environment that lets developers build powerful Claude-based agents with deep integrations into their daily workflows. Running on Electron with a Node.js + Express backend, it connects the Claude Agent SDK to Composio’s Tool Router so your agents can operate across more than 500 external services, from Gmail and Slack to GitHub and Google Drive.

With persistent, multi-session conversations, Open Claude Cowork keeps long-running projects organized and context-aware. Real-time streaming responses via SSE provide smooth, token-by-token outputs, while tool call visualization in the sidebar reveals every request and response your agent executes. This makes debugging and refining complex automations far easier.

Key capabilities include:

• Claude Agent SDK integration for multi-turn reasoning with structured tool use
• Composio-powered tool routing to hundreds of third-party APIs
• Persistent chat sessions for ongoing projects and workflows
• Multi-chat workspaces to separate experiments, clients, or repositories
• Todo-style progress tracking so agents can manage task lists alongside conversations

Designed as a native Electron desktop experience for macOS, Windows, and Linux, Open Claude Cowork offers a dark, Claude.ai-inspired interface that feels familiar yet fully customizable. The repository includes a guided setup script that configures Composio, environment variables, and dependencies, helping you go from clone to working AI agent environment in minutes.
