I Built a 24/7 AI Agent System on a $6/Month VPS — Here's the Stack

The Setup

Running a fully autonomous AI agent on Hetzner VPS (€3.9/mo).

Stack:

• OpenClaw agent framework (open source, MIT)
• DeepSeek V4 Pro via NVIDIA NIM API (1.6T MoE, 1M context)
• Playwright + Python for browser automation
• Docker container for isolation

What it does autonomously:

• Posts content to Twitter/X every 5 minutes
• Publishes Dev.to articles every 30 minutes
• Manages Gumroad digital product store
• Sends targeted promotions

Why DeepSeek V4 Pro?

Released April 24, 2026:

• 1M token context (real, tested)
• $1.74/1M input vs Claude $3
• Think/Non-Think dual modes
• MIT license

5x cheaper than Claude Sonnet 4.6 for typical agent workloads.

The Result

89 AI productivity guides packaged and selling on autopilot.
