Draw your whole stack on one page.

Your stack works in dev and nobody has tested the rest.

• →Every architecture guide assumes AWS and a $5,000 monthly bill. You need the version that runs on a real budget.
• →Half the AI infrastructure content out there is a Notion template. No code, no config files, nothing you can deploy.
• →It works locally. You have no idea what happens at ten times the traffic, and you will find out on the worst possible day.
• →You can name your services. You cannot name what fails first, which is the only thing that matters at 3am.

Six layers, every fallback, one diagram.

• 01
  The full topology

  Frontend, backend, database, agent layer, payments and monitoring on one page, with the wiring drawn rather than described.
• 02
  Where the agents live

  How Claude Code, OpenClaw and your MCP servers sit inside the stack instead of bolted onto the side of it.
• 03
  The payments decision

  Stripe against Fan Basis as a decision tree keyed to your ops maturity, not to whichever one has better docs.
• 04
  Deploy and watch

  Hetzner, Railway and Hostinger compared on real workloads, plus the Sentry and Resend wiring that tells you before a customer does.
• 05
  What breaks first

  The failure order under load, layer by layer, so you harden the thing that actually goes rather than the thing you read about.

You, if your architecture only exists in your head.

If you are shipping an AI product and the design lives across three browser tabs and a memory, this gives you the written version. Copy the diagram, swap the services you have already committed to, keep the fallbacks.

Why now The agent layer is new enough that most architecture writing predates it entirely. Every diagram from two years ago has a hole where MCP and long-running agents now sit.

The real payoff arrives the first time something breaks and you already know which layer it is. Debugging stops being archaeology and starts being a checklist.
