NanoClaw

What it is

NanoClaw is a lightweight, AI-native personal assistant framework designed as a secure, containerized alternative to OpenClaw. It runs on the Claude Agent SDK and prioritizes codebase simplicity and OS-level isolation.

What problem it solves

It addresses the security risks and code complexity of heavy agent frameworks by providing a minimalist, container-first assistant that evolves through self-modification and composable skills.

Where it fits in the stack

Development & Ops / Personal Assistant. It is a lightweight agent framework for individuals and developers.

Typical use cases

  • Secure, sandboxed AI assistance for personal local tasks
  • Building custom multi-channel agents (WhatsApp, Telegram, etc.)
  • Prototyping agent swarms in a low-complexity environment

Strengths

  • Security-First: Native container isolation; agents run in ephemeral Linux containers by default.
  • Minimalist: Small codebase, easy to understand and fork.
  • Self-Modifying: Can evolve its own features through code transformations via the Anthropic Agent Skills protocol.
  • High Efficiency: Optimized layer templates can reduce token costs by up to 40% compared to unoptimized RAG patterns.

Limitations

  • Claude-Centric: Primary optimization is for Claude models; other models may require custom adapter work.
  • Self-Modification Risk: Requires comfort with an assistant that writes its own logic (can be disabled via NC_READONLY_MODE=true).
  • Resource Minimums: Requires at least 4GB RAM and Docker 24+ for the isolation layer to function correctly.

When to use it

  • When you want a personal AI assistant that can be fully understood and customized (low code complexity).
  • When you require strong security via Linux container isolation (Apple Container or Docker).
  • If you prefer a "skills over features" model where the assistant evolves through code transformations rather than configuration.

When not to use it

  • If you require a managed service or a complex, multi-user enterprise framework.
  • If you are not comfortable with an assistant that modifies its own source code to add features.

Key Features

  • Container Isolation: Agents run in sandboxed Linux containers, seeing only explicitly mounted directories.
  • Skills-Based Architecture: Uses Anthropic Agent Skills to add capabilities (e.g., /add-whatsapp, /add-telegram) by dynamically rewriting the NanoClaw codebase.
  • Multi-Channel: Supports WhatsApp, Telegram, Discord, Slack, Gmail, and more.
  • Agent Swarms: First personal assistant to support collaborative teams of agents.
  • Small Footprint: Designed to be small enough for a single developer to understand the entire codebase.

Getting started

Requirements

  • macOS or Linux
  • Node.js 22+ (Baseline as of May 2026)
  • Claude Code
  • Docker 24+ (or Apple Container on macOS)
  • 4GB+ RAM

Installation

# Clone the repository
git clone https://github.com/qwibitai/nanoclaw.git
cd nanoclaw

# Use Claude Code for guided setup
claude /setup

Verifying Isolation

To ensure your agent is correctly sandboxed, run the following command within the NanoClaw environment: 

nanoclaw exec "echo 'hello' > /root/secret.txt && ls /root"
Then verify that a new container cannot see that file.
