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. Hardware-matched. "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 experimentation.

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.…
