The Self-Hosted Stack That Runs My Infrastructure

Over the past few weeks, I have written about AutoMaintainer, mago, SuperCLI, SuperInsights, machin, and a2a. Each article described a product or tool in isolation. But the real story is how they work together.

This is the stack that runs Intrane — a fully self-hosted infrastructure that costs less than a SaaS subscription and gives me more capability than any single platform I have used.

The Core Loop

At the center is AutoMaintainer. It runs a verified gate across all my repositories — whenever an issue is filed or a schedule triggers, its multi-agent fleet (powered by a2a) starts working. Agents write code, review each other, run tests, iterate on failures, and land merge-ready PRs. I review and merge. That is the daily workflow.

When a project is too early for the full AutoMaintainer pipeline — an experiment, a one-off script, a bootstrapper MVP — mago takes over. One worker, one repo, €20/month. Same BYOK model, same agent-driven approach, less ceremony.

The Tool Layer

Every engineer on the stack runs SuperCLI. It is the universal entry point for every tool in the ecosystem. sc deploy, sc logs, sc db:backup, sc blog:publish. No context-switching between package managers, no "where is that script?" — just one binary with every tool available.

Tools built with machin — the machine-first language — are the backbone of this layer. machin-auth handles authentication for every internal service. machin-hook relays webhooks during development. machin-terminal is the terminal I use daily. Each is a single static binary with zero dependencies. They deploy in seconds and run on any Linux machine.

The Data Layer

SuperInsights collects analytics from every service. Page views, API calls, error rates, performance — all self-hosted, all raw, all queryable. The data feeds back into AutoMaintainer's decision-making: when error rates spike on a recently deployed change, the fleet knows to roll back before I wake up.

MongoDB and SQLite handle the rest. MongoDB for structured data, SQLite for agent conversations (a2a's message bus) and ephemeral state. No cloud databases, no third-party storage — everything runs on a single $10/month VPS.

What It Costs

• VPS: €10/month — runs everything
• AI tokens: ~€50/month — BYOK, direct provider pricing, no markup
• AutoMaintainer: included in Intrane subscription
• Everything else: open source, self-hosted, €0

Total: ~€60/month for a self-hosted infrastructure that replaces GitHub Actions, Vercel, Google Analytics, Sentry, Auth0, webhook.site, and more. No per-seat pricing, no usage tiers, no surprise bills.

The Philosophy

This stack is not about saving money — though it does. It is about ownership. Your infrastructure should run on your terms. Your data should stay on your servers. Your AI agents should use your keys. Your tools should fit in a single binary.

Every product in this series is open source (MIT). Every tool is self-hostable. Every service is designed to be replaced if something better comes along. No lock-in, no vendor dependency, no "migrate to our platform" pitch.

This is the infrastructure I trust to run my business. It is available for yours too.
