I ditched OpenClaw and built a more secure AI agent (Blink and Mac Mini)

7 hours ago

OpenClaw gained popularity as a personal AI assistant but faced security issues due to default public internet exposure.
Security concerns with OpenClaw included accidental exposure of shell, browser automation tools, and API keys.
The author built a secure personal AI agent using Blink (agent platform) and Tailscale (security layer) on a Mac Mini.
Blink provides isolated containers for each agent, ensuring separation of tasks and credentials.
Tailscale ensures the system is invisible to the public internet, requiring cryptographic authentication for access.
The setup includes specialized agents for business and personal tasks, improving response quality and security.
Blink supports multi-channel messaging (Telegram, SMS, WhatsApp) with lightweight adapters for each platform.
Cost-effective with minimal ongoing expenses: ~$19/month for Mac Mini, ~$1.50 for electricity, and $5-15 for AI model usage.
Key security features: no public internet exposure, isolated containers, cryptographic authentication, and granular permissions.
The entire system was built in two weeks using open-source tools, emphasizing security from the start.
