NanoClaw

Security-focused OpenClaw alternative — container isolation, minimal surface

NanoClaw is a lightweight, open-source AI assistant designed as a security-focused alternative to OpenClaw. It addresses concerns about OpenClaw's complexity and attack surface by using a single Node.js process with just 5 core files (vs OpenClaw's 52+ modules and 45+ dependencies). Agents run in isolated Linux containers (Docker or Apple Container) with filesystem isolation—rather than directly on your machine with unrestricted host access.

NanoClaw is lightweight enough to run on a Raspberry Pi and uses the official Claude Agent SDK. The trade-off: it's Claude-focused only (no multi-LLM support) with a minimal plugin ecosystem compared to OpenClaw's 100+ community skills. This site does not endorse or maintain NanoClaw; we include it for discovery. See the NanoClaw GitHub repository for the project.

Key Features

  • WhatsApp integration — Control via WhatsApp with per-group isolated contexts and memory files
  • Container isolation — Agents run in Docker or Apple Container; sandboxed filesystem access
  • Scheduled tasks — Recurring jobs that run Claude and message results back
  • Agent swarms — Multiple collaborative agents for complex tasks
  • Web access — Built-in search and content fetching via Claude Agent SDK
  • AI-native setup — Claude Code handles configuration and troubleshooting

When to Choose NanoClaw

  • You want stronger security defaults—container isolation vs unrestricted host access
  • You prefer a minimal, auditable codebase—5 core files vs OpenClaw's large surface
  • You're okay with Claude only—no OpenAI, Ollama, or multi-provider routing
  • You don't need OpenClaw's full skill ecosystem (ClawHub, browser automation, etc.)

Choose OpenClaw when you need the full platform: hundreds of skills, 15+ channels, browser tools, multi-LLM support, and the largest community.

NanoClaw vs OpenClaw

  • Architecture — NanoClaw: single Node.js process, 5 files. OpenClaw: 52+ modules, 45+ dependencies.
  • Security — NanoClaw: agents in isolated containers. OpenClaw: agents run on host with configurable sandboxing.
  • LLM support — NanoClaw: Claude only. OpenClaw: Anthropic, OpenAI, Ollama, Gemini, and many more.
  • Skills — NanoClaw: minimal plugins. OpenClaw: ClawHub with 100+ community skills.
