I Built Infrastructure for 20 AI Agents That Run Themselves — For €4.57/Month

Five months ago, I couldn't get one AI agent to finish a build without breaking. Today, I have 20 autonomous agents running cron jobs, self-improving, and catching each other's bugs — all on a €4.57/month VPS.

Here's what I built, what broke along the way, and why I'm not charging for any of it yet.

What's Actually Running

• workswithagents.dev — A knowledge API that agents query for facts, skills, and known bugs. Think "Stack Overflow but agents are the users."
• workswithagents.io — A blueprint registry of verified LLM configurations. "This Qwen model on this M4 Mac gets 22 tokens/sec — verified."
• workswithagents.com — The education side. Teaching the methodology that emerged from all this.
• bastiongateway.com — Operations infrastructure. License server, heartbeat monitoring, agent proxy.

All five domains live. All three APIs healthy. Total monthly cost: €3.99 for a Hetzner CX23 + €0.58 for IPv4. Less than a coffee subscription.

The 10 Patterns

I didn't plan to build a methodology. I was just trying to make agents work. Over 5 months of breaking and fixing, patterns emerged:

1. Boot — First session setup. Without it, every agent starts blind.
2. Skills — Reusable knowledge. I now have 153 skills. No re-explaining.
3. Memory — Durable facts across sessions. Never re-answer the same questions.
4. Decision Protocols — When the agent decides vs when it asks. Hours saved.
5. Tool Composition — The right tool for each job. Delegating coding to subagents burns tokens.
6. Orchestration — Parallel specialist agents. 3x throughput on multi-stream tasks.
7. Pipelines — Agents that run while you sleep. Cron jobs, builds, monitoring.
8. Resilience — Never-stop loops. 11 consecutive builds. Zero human intervention.
9. Verify — Trust but verify. Every change gets checked before it ships.
10. Compounding — Agents that get better. Each solved problem becomes a skill.

What's NOT Ready

Thing	Status
5 domains live	Done
3 APIs serving real data	Done
153 skills queryable	Done
10-pattern methodology	Done
Courses	Content written, not launched
Paying customers	Zero

I'm not selling anything until the methodology is proven with real users. This is pre-revenue, pre-launch, pre-everything commercial. I'm shipping infrastructure, not promises.

The Bigger Play

Everyone's building agents. I'm building infrastructure FOR agents. Agents need shared knowledge. They need verified configurations. They need to know what breaks and how to fix it. They need to hand off work without losing context.

These are the picks and shovels of the agent gold rush. And most people haven't realised the gold rush needs picks and shovels yet.
