Pick an application. We build the rest.

What about the other 15?

You can still have them. Those 15 need a license key from their maker, or a runtime we will not hand a shared tenant, so ordering one raises a job with us instead of running a script. We set it up on your site and tell you when it is live. There is no charge for it: the application is free, you are already paying for the site it goes on.

What if something goes wrong halfway?

Every step that succeeded is undone in reverse order, and the ones that were skipped because they were already done are left alone. The site is put back the way it was. If you are installing over a directory that already has something in it, the panel stops, tells you what it found, and takes a full copy of files and database before it goes anywhere near it.

Do I get a real login, or a half-finished setup?

A real one. The install creates the administrator account, the database and its own user with a generated password, and the certificate, and it hands you the address to sign in at. Nothing here asks you to finish it off in a wizard afterwards.
