Building a Production Multi-Agent System on a $13/month VPS with CrewAI and Gemini
Original: Day 1 — I'm Homeless. I Just Shipped an Autonomous Multi-Agent System.
Short summary
Developer deployed a production multi-agent system with CEO, researcher, writer, and auditor roles using CrewAI and Gemini on a $13/month VPS. Architecture uses config-driven YAML (never code edits) with all changes git-tracked for safety and auditability. CEO agent analyzes KPIs nightly and approves/rejects worker proposals based on hard metrics, not hallucinations.
- •Built multi-agent system on $13/month bootstrap budget using CrewAI and free Gemini tier
- •Config-driven architecture (YAML) prevents agents from modifying executable code—all changes are git commits
- •CEO agent governs worker proposals using actual KPI data, not intuition or hallucinations
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
