NullClaw: Ultra-Lightweight 678KB AI Assistant with OpenClaw Migration Support
NullClaw: 678KB Ultra-Lightweight AI Assistant
Overview
NullClaw is a fully autonomous AI assistant infrastructure written in Zig. The most impressive part: the entire runtime is just 678KB - smaller than most images you send on Slack.
Why NullClaw?
Most AI assistants are bloated multi-gigabyte binaries that require complex dependencies and can't run on low-end hardware. NullClaw takes the opposite approach and delivers a complete AI assistant as a single static binary with zero runtime dependencies.
Core Features
Architecture Advantages
- Built with Zig's vtable-driven architecture
- Every extension point is explicit and swappable
- Boots in milliseconds
- Runs on $5 boards
Functionality
- Multi-channel support: Telegram, Discord, Signal, WeChat
- Multi-provider: OpenRouter, Ollama, Groq, local models
- Gateway runtime: with heartbeat and scheduler
- Memory migration: from OpenClaw
- Interactive onboarding wizard
Deployment Benefits
Size and dependencies directly determine where you can deploy. A 678KB binary with zero dependencies runs on:
- Edge devices
- Old phones
- Cheap boards
- Containers
These are scenarios that multi-GB alternatives can't touch.
Open Source
NullClaw is 100% open source.
Relationship with OpenClaw
NullClaw supports memory migration from OpenClaw, meaning if you're already using OpenClaw, you can seamlessly migrate to this more lightweight solution.
