Deploy Wiki.js on Pethost in one click

What happens

1. You sign in to Pethost or make an account, with a passkey, GitHub or Google.
2. No machine yet? You pick a plan, and we prepare one for you. The link waits in your browser until it is ready.
3. New project opens at the app. You fill in what it asks for and click Create project: Email, Admin password.
4. In a minute or two the app is live at its own address with HTTPS. Its secrets are made for it at random, and its data is in the nightly backup.
5. It is a project like any other: its compose.yaml, its .env, its logs and a terminal are in the panel, and your agent can change it, roll it back or restore it.

First steps

Sign in with the email and the admin password you gave: Wiki.js is set up with them before it answers, so nobody else gets its setup page. Pages are created from the home page; users, groups and sign-in providers are under Administration.

What it runs

The template is this compose.yaml and the variables it writes into the project’s .env. Pethost runs the file as it is written.
