One Mac mini runs the company.
No platform bill that grows with traffic. A single machine in Tallinn runs every site and service, a standby server outside the home network is ready to take over, and tooling we wrote ourselves keeps both healthy without anyone watching.

The path of a request
What keeps it running
- 0165 KB/supload from home, too slow to serve media
The edge
Nothing at home listens on the open internet. One Cloudflare tunnel carries traffic for 25 hostnames to a web server on the Mac. The Mac's upload through the tunnel is slow, about 65 KB/s, so images, video and fonts never come from it: a small Worker serves them from R2, reads through to the Mac on a miss, rechecks freshness every ten minutes per location and falls back to the Mac on any error.
- 0263 saverage successful deploy
Deploys
A deploy builds with secrets pulled from an encrypted vault (AES-256-GCM), writes into a fresh folder, swaps it in atomically and restarts the service. If several changes arrive at once, the latest wins. A failed install is retried once. The average successful deploy takes 63 seconds.
- 0360 sbetween health checks, every environment
Watching itself
Every environment is health-checked every 60 seconds. Two failures in a row send an alert to a phone, and error rates in the web server logs raise alerts too. Services run under launchd with KeepAlive, so a crash is a restart, not an outage.
- 042 minbetween watchdog runs
Repairing itself
A watchdog runs every two minutes and restarts the web server or the private network if they stop answering, with a ten-minute cooldown so it cannot thrash. A separate check confirms every deploy is still healthy every 15 minutes.
- 05~5task board sweeps a day
Agents on the dross
Routine work goes to automated harnesses. An agent sweeps the task board about five times a day, closing what is verifiably done and flagging what is not. Others keep the books and draft routine replies. Decisions, taste and anything a customer sees stay with a person.
- 060per-request fees
What it costs
No per-request pricing and no fleet to rent. The running costs are a few small subscriptions, one small standby server and the electricity for one Mac mini, so nearly all of what a product earns is margin. It also means a product can stay alive for years without needing to grow to pay its hosting bill.
If the Mac mini goes down
A single machine at home would be a single point of failure, so it has a standby. A rented server outside the home network keeps an up-to-date copy of every public site, forms included. A watchdog on Cloudflare's edge, independent of both machines, checks the sites from outside. If they stay unreachable for 5 minutes, it moves traffic to the standby on its own, and moves it back once the Mac answers again. The same server also runs the heavier work: high-load services, APIs for larger enterprise applications and customer-facing services.
