NanoClaw

NanoClaw is a lightweight personal AI assistant that runs as a single Node.js process, designed to provide users with a simple yet powerful way to interact with Claude through WhatsApp. Unlike many complex AI tools that rely on microservices, message queues, or heavy infrastructure, NanoClaw operates with just five core files and one process, making it extremely easy to set up and maintain. The system is built on the Claude Agent SDK, allowing it to leverage Claude’s reasoning and tool-use capabilities in a self-contained environment. One of the key features of NanoClaw is its container-based isolation for security. Each agent runs inside a Linux container with filesystem isolation, meaning that only explicitly mounted directories are accessible to the agent. Bash commands executed by Claude are safely contained within these containers, never affecting the host system. This design allows users to delegate tasks like file management, script execution, or data processing to the assistant without risking their local environment. NanoClaw integrates directly with WhatsApp, enabling users to chat with Claude through a familiar messaging interface. Users can send text messages, request information, ask Claude to perform actions, or even trigger scheduled tasks. The assistant supports per-group memory, meaning conversations and context are stored separately for each WhatsApp group or chat, allowing Claude to maintain coherent and personalized interactions across different contexts. Scheduled tasks can be configured to run automatically at specified times, such as daily reports, reminders, or data fetches, all handled by the same process without additional cron jobs. The tool is production-ready (current version v0.4.2) and has gained over 6,700 GitHub stars, indicating active
