Overview

Electron desktop chat client with a Node/Express backend that runs the Claude Agent SDK, or optionally the Opencode SDK, and streams responses over SSE. It reaches 500+ apps (Gmail, Slack, GitHub, Google Drive) through Composio Tool Router and MCP, and loads custom skills from .claude/skills/. The repo also bundles Secure Clawdbot, a separate messaging bot for WhatsApp, Telegram, Signal and iMessage.

Who it is for: Developers wanting a Claude-based desktop agent wired to work apps

Strengths

  • Tool inputs and outputs are shown in a sidebar during streaming responses
  • Loads custom SKILL.md files from .claude/skills/
  • Opencode SDK provider is available alongside the Claude Agent SDK
  • Includes a messaging bot with memory, browser automation and scheduled reminders

Weaknesses

  • Requires an Anthropic API key and a Composio API key; no local model path described
  • Needs a separate backend started in its own terminal before the app
  • No Docker image or packaged release; setup is clone and run setup.sh
  • Integrations depend on the hosted Composio service

What it needs

  • no GPU
  • Needs Anthropic API key, Composio API key, Opencode API key (optional), Node.js, Electron
  • Models: Claude (Claude Agent SDK), Opencode SDK models
  • port 3001
