## What it is
NullClaw is an autonomous AI assistant/agent runtime written in Zig, distributed as a tiny static binary (~678 KB, ~1 MB RAM, <2 ms startup) with no external dependencies. It bundles 50+ LLM providers, 19 messaging channels, 35+ tools, pluggable memory engines, sandboxing, MCP support, and a CLI/gateway operator surface.

## Use cases
- run an autonomous AI agent on a cheap ARM board or microcontroller
- self-host a personal AI assistant that works over Telegram, Discord, or Slack
- let an agent refactor code, run tests, and open PRs from the terminal
- route one assistant across OpenAI, Anthropic, Ollama, and local models
- give a chatbot persistent memory across sessions
- run an AI agent with strict sandboxing and allowlists on an edge device

## When to choose
- you need an extremely lightweight, zero-dependency agent runtime for edge or low-resource hardware
- you want a single self-hosted binary that multiplexes many LLM providers and chat channels
- security matters: you need sandboxing, pairing, allowlists, and encrypted secrets by default
- you prefer fast startup and minimal memory footprint over a heavyweight framework

## When to avoid
- you need a rich GUI-first experience out of the box (the NullHub UI layer is still in beta)
- you want to extend the runtime in Python or JavaScript rather than Zig
- you need mature integrations or a large plugin ecosystem beyond the built-in tools and channels
- your team requires long-term enterprise support or a large community around the tool
