Four rules, and the software that keeps them.
A bothy works because everyone who uses one follows the same four unwritten rules. They turned out to be a decent specification for software.
A bothy is an unlocked shelter in the hills.
No booking, no front desk, no one charging you. You walk in, you work, you leave it better than you found it. The door is open to whoever's in the crew that day.
That's the whole idea, applied to software. Not luxury — the essentials, always there and always open.

Stocked for whoever comes next
You arrive at a bothy and there is firewood by the stove, candles on the shelf and a book by the door, because the last person left them. Nobody was asked to. It is just how the place works.
Bothy is built the same way. The daily log, the notes on a ticket, the runbook someone wrote once — a crew spread across time zones runs on what the last person left behind.
The door is open.
Thirty days free for a team, free forever for one person. If it does not replace at least three things you pay for, do not keep it.
