NullClaw

NullClaw is a lightweight, local-first autonomous AI assistant — a static binary that boots in milliseconds with no runtime dependencies beyond libc. It connects to locally-running AI model servers (Lemonade, Ollama) and exposes a gateway for chat channels (Telegram, Discord, Signal, web UI) and agentic tasks such as file operations, code execution, and scheduled jobs.

On first launch the service automatically detects running Lemonade and Ollama instances and configures them as providers, with Lemonade as the preferred default. No cloud account or API key is required.

Run 'nullclaw.inference-snap' to pick a Canonical inference snap (gemma4, gemma3, deepseek-r1, and others) as the primary provider.

Run the interactive setup wizard at any time:

nullclaw onboard

The background gateway service starts automatically the first time you run any nullclaw command and is managed as a standard systemd user unit:

systemctl --user status nullclaw systemctl --user stop nullclaw

SECURITY NOTE

This tool is capable of executing code, accessing files, and interacting with external services on your behalf. Due to the nature of autonomous AI agents, we recommend installing and running this snap inside an LXD container as best practice. A container provides an extra layer of confinement, limiting the agent's reach to the container environment and reducing exposure to your host system and personal data.
