🔒 Security Considerations

⚠️ Moltbook Database Exposure (January 2026): A public Moltbook instance exposed user data due to misconfigured database settings. Always use `openclaw doctor` to audit your configuration before deployment.
⚠️ "What Would Elon Do?" Malicious Skill: A skill named "What Would Elon Do?" in ClawHub was found to silently collect user data. Always review skill code before installing, especially from untrusted authors.

Frequently Asked Questions

What is the Claw family?

The Claw family is a collection of open-source AI agent frameworks that share a common philosophy of personal AI ownership. They originated from OpenClaw (formerly Clawd/Moltbot), which went viral in 2025 with its lobster-themed personal assistant.

What's the difference between OpenClaw and the others?

OpenClaw is the full-featured "kitchen sink" framework with multi-channel support, multi-agent routing, and a local-first gateway. PicoClaw and ZeroClaw are focused, lightweight alternatives for specific use cases (embedded devices and production security, respectively).

Can I use ClawHub skills with any Claw framework?

Yes! ClawHub skills are designed to work across the Claw family. While OpenClaw has the most complete integration, PicoClaw and ZeroClaw also support the skill format.

Which framework is best for beginners?

For beginners, we recommend starting with nanobot for simple chat bots or OpenClaw if you want full functionality. OpenClaw has excellent documentation and a large community. PicoClaw and ZeroClaw require more technical familiarity.

Do I need to pay for API usage?

All Claw frameworks are open-source and free. However, they connect to LLM providers (OpenAI, Anthropic, etc.) which have associated costs. Some frameworks support local models for offline use.

Is the Claw family secure?

The Claw family prioritizes security with tool permissions, audit logs, and configuration checking tools. However, like any AI agent framework, you should review skills before installation and use sandboxed environments for code execution. See the Security section above for details on past incidents.
